    In the post-industrial era, popular cars faster than we imagined, convenient and efficient in bringing the same time, a lot of exhaust emissions, but also adds a lot of pressure to the environment, and as oil prices and caused carbon dioxide emissions of greenhouse highlight the effects of such issues, it is an urgent need to find new energy sources to replace traditional energy sources. Liquid hydrogen, fuel cells are a good choice, but there are high prices, immature technology and so on, ordinary lead-acid battery costs are relatively low, but the weight of heavy, low energy density, short life, there is a potential heavy metal pollution. Chengdu into a “zero discharge” of all-electric bus, received extensive attention, this all-electric bus using the new lithium iron phosphate as its power core, this new generation of green power electric car has many features and advantages.

    High security

    To as motor power, security is the overriding consideration. Despite the general safety of lithium batteries can be basically guaranteed, but there is a fire in extreme conditions, the possibility of explosion. Lithium iron phosphate as the second generation of lithium products, their physical properties, coupled with the battery pack built-in over voltage, under voltage, over current, over charge protection, the non-explosion no fire, is the only absolute safety of lithium ion batteries.

    As a result of high thermal stability of materials and careful process design, battery safety and reliability greatly increased. And improper use of lithium battery explosion phenomenon may occur compared to lithium iron phosphate even throw in the fire will not explode. High temperature stability up to 400-500 ° C, ensuring high security internal battery; will not overcharge, overheating, short circuit, the impact on explosion or combustion. Rigorous safety testing, even in the worst traffic accident would not explode.

    Long life and low cost

    As the battery service life (cyclic performance) and is closely related to the overall use of the cost, and ordinary lithium battery is about 500 times compared to the cycle of life, iron phosphate lithium battery can charge and discharge at room temperature 1500 cycle, the capacity retention rate of 95% more, 50% of the capacity of the cycle of life is to reach more than 2,000 times the battery life of more than 50 continuous miles kilometers, you can use about five years, is 8 times the lead acid batteries, nickel hydrogen batteries 3 times, is lithium cobalt oxide is about 4 times. Plus the cost of their production is itself less than ordinary lithium batteries, electric cars will undoubtedly be able to greatly reduce the use and maintenance costs.

    Discharge performance of lithium iron phosphate also very excellent, smooth power curve, had put strong resistance to the ordinary lithium batteries in less than 3.2V, then discharge is put, may be scrapped as a result. However, in 2.8V lithium iron phosphate release of energy when there is less than 2.5V scrapped problem does not exist.

    Easy to use treatment

    We know that nickel metal hydride, nickel cadmium batteries there is a strong memory effect, have certain common lithium battery memory effect problem and needs to try to “over full release”, the daily use of electric cars will cause inconvenience, and lithium iron phosphate-free this phenomenon, since the discharge is small; no memory effect, no matter in what state the battery can be used with rechargeable with no need to recharge the first had finished, while the outstanding characteristics of the battery fast charge, fast charge with a charger, a half-hour can give a 95 % or so. Treatment after the end of battery life issues, also deserves our attention, lithium iron phosphate does not contain any heavy metals and rare metals, non-toxic, pollution-free, meet the requirements for absolute environmental protection batteries, lead acid batteries there are high levels of lead , after its abandonment, if not handled properly, will constitute a secondary environmental pollution, lithium iron phosphate material in terms of production and use, are non-polluting.

    Overall, lithium iron phosphate as a new generation of lithium battery materials, is absolutely reliable for its safety, long cycle life, stable platform, the advantages of charging and discharging battery by global experts also praised, worthy of a new generation of electric vehicles for the green power of core products, with the electric buses in the practical application of the successful demonstration, it will gradually replace lead-acid batteries, in the current public use of electric bicycle in Chengdu has been widely used.

    2010, the industrialization of new energy vehicles officially launched a large-screen, state support policy from buses, taxis and other public services to expand to larger markets private consumption. This year in June, the private purchase of new energy vehicles subsidy policy introduced the pilot opened the door to private consumption subsidies. The industry believes that the expansion of the private consumer market means that areas of new energy automotive industry embarked on a rapid development of the “right track.”

    In this regard, the capital market is also an implicit benefit the field of new energy vehicles, or likely to benefit companies continue to be a hot market. New energy to the battery vehicle manufacturers, to the upper reaches of battery materials, the focus of the whole industry chain of your company Changba me play, the secondary market was bustling. In the car with the new energy field, the maximum cost share of the battery, can generate the highest value-added is also expected, including the most popular areas of strong lithium.

    Lithium battery will become mainstream

    Compared with conventional cars, new energy automotive industry chain based on the extension and increase the battery, motor, electric control system components. Battery is new energy automotive industry chain of the most core part. New components in new energy vehicles, the battery system costs account for most new, this link is also expected to generate the highest added value. According to estimates, battery electric vehicles in the cost of composition as much as 60%.

    Now as a new energy vehicles for the battery power source mainly lead-acid batteries, nickel hydrogen batteries and lithium ion batteries, widely believed to be the mainstream lithium battery. Lithium-ion batteries are light weight, energy and high specific power, small size, long cycle life, no memory, self-discharge rate, temperature, wide range of applications and many other advantages, but also a large improvement and cost reduction technology space Therefore, the medium and long term, will gradually achieve lithium battery market to replace nickel-hydrogen batteries.

    Lithium take four investment areas

    Judging from the structure of lithium-ion battery consists mainly of four parts: the cathode material, anode material, electrolyte, membrane and auxiliary materials such as ultra-thin copper foil. Which cathode material, electrolyte and membrane is the core of the three materials, directly determine the performance of battery safety, capacity, accounting for the cost of lithium-ion battery more than 70%. The most commonly used cathode material for lithium batteries are mainly lithium cobalt oxide, lithium manganese, nickel, lithium, ternary materials, and lithium iron phosphate.

    By comparison, lithium iron phosphate cathode material is the best it discharge power, low cost (about 180,000 ~ 200,000 yuan / ton), fast charging and long cycle life (over 1000), at high temperature high stability under high heat.

    Mainly graphite anode materials, graphite fiber materials, etc, the production of technical barriers to low, stable supply of upstream and downstream relationship is the key to competition in the industry, competitive landscape is relatively stable. China has a lot of enterprises engaged in production of anode material for lithium. .

    The safety performance of the lithium battery separator has a tremendous effect in the cost of lithium batteries represent about 25% of the composition of the ratio, but the gross profit margin as high as 70%, the power lithium battery in the most profitable part. Diaphragm made public until 2005, but the ratio of foreign and domestic diaphragm thickness, strength, pore overall absorption rate can not be both, and the stability of the general, the major supplier of low-end market.

    Electrolyte lithium battery costs account for about 15%, gross margin of about 40%. At present, production capacity of 1.8 million tons of supply and demand balance, but the new energy future demand for automotive vehicles driving on the electrolyte more.

    In addition, the electrolyte is the main raw material of lithium hexafluorophosphate, accounting for more than 50% of the cost of the electrolyte. As the production of high technical difficulty, electrolyte market is monopolized by the Japanese several enterprises, Chinese enterprises have not fully mastered the production technology, the current trial of lithium hexafluorophosphate listed company is of Jiangsu Guotai and Fluoride.

    1. Liquid Electrolyte
    Selection of electrolyte on the performance of lithium-ion batteries are very large, it must be good chemical stability, especially in high potentials and high temperature environment less prone to decomposition, with a high ionic conductivity (> 10 – 3 s / cm), and on the anode and cathode materials must be inert and can not invade them rot. As the lithium-ion battery charge and discharge potential and the anode material containing a high chemical reactivity of lithium, the electrolyte must not contain water with organic compounds. However, the ionic conductivity of organic matter are not good, so soluble in organic solvents by adding salt to increase the conductivity of ionic conductivity. Current lithium ion batteries are mainly used liquid electrolyte, the anhydrous organic solvent such as EC (ethyl carbonate), PC (propylenecarbonate), DMC (dimethyl carbonate), DEC (diethyl carbonate), the majority of mixed solvents, such as EC2DMC and PC2DMC . Conductive salt with L iClO4, LiPF6, LiBF6, LiA sF6 and LiOSO2CF3, the order of their conductivity LiAsF6> LiPF6> LiClO4> LiBF6> LiOSO 2CF3. LiClO4 due to oxidation of high explosive and so prone to security issues, generally confined to experimental studies; LiAsF6 easy to purify high ionic conductivity and good stability, but contain toxic As, limited use; LiBF6 Chemistry and good thermal stability and conductivity is not high, LiO SO2CF3 poor electrical conductivity and corrosion of the electrodes have, less use; Although LiPF6 will decompose, but with higher ionic conductivity, so far the basic lithium-ion battery is to use LiPF6. Current commercial lithium-ion battery electrolyte used in the majority of use LiPF6 the EC2DMC, it has a high ionic conductivity and good electrochemical stability.

    2. Solid Electrolyte
    Directly with lithium metal as anode materials with high reversible capacity, its theoretical capacity of up to 3862mAh · g-1, is a graphite material 10 times, lower prices, is seen as a new generation of lithium-ion batteries the most attractive anode material, but will produce lithium dendrite. Using solid electrolyte ionic conductivity as the lithium can inhibit the growth of dendrites, making it possible anode materials for lithium. In addition, use of solid electrolyte leakage of liquid electrolyte to avoid the shortcomings of the battery can be made thinner (thickness of only 0.1mm), higher energy density, smaller high-energy batteries. Destructive experiments show that solid-state lithium-ion battery safety is high, by nailing through the heating (200 ℃), short circuit and over charge (600%) and other destructive experiment, the liquid electrolyte lithium-ion battery leakage occurs, explosions and other safety issues, and solid-state batteries within the temperature slightly higher than outside (<20 ℃) there is no other security problems. Solid polymer electrolyte has good flexibility, film formation, stability, and low cost, both positive and negative electrodes as a membrane with the electrolyte ions can use as a transfer.
    Solid polymer electrolyte can be separated into dry form solid polymer electrolyte (SPE) and gel polymer electrolyte (GPE). SPE solid polymer electrolyte are mainly based on polyethylene oxide (PEO), the drawback is a lower ionic conductivity, at 100 ℃ can reach 10-40cm. Ion conduction in the SPE is mainly in the amorphous region, with the movement of polymer chains pass migration. Easy crystallization of PEO molecular chains because of its high regularity, and crystal technology will reduce the ion conductivity. So in order to improve the ionic conductivity on the one hand can reduce the polymer crystallinity, increase chain mobility, on the other hand can enhance the conductivity of salt in the solubility of the polymer. Use of graft, block, cross-linking, copolymerization and other means to destroy the crystallization properties of polymers can significantly improve the ionic conductivity. In addition, inorganic salt complexes can be added to improve ion conductivity. In the solid polymer electrolyte by adding high dielectric constant of the liquid low molecular weight organic solvents such as PC can greatly improve the conductivity of salt solubility, the composition of the electrolyte shall GPE gel polymer electrolyte, which at room temperature with high ionic conductivity, but the process will occur in the use of liquid and failure analysis. Gel polymer lithium-ion batteries have been commercialized.

    Form January to February this year, Fujian Province exports battery to the EU in 32 million.They worth $ 560 million and the value of export just after Hong Kong.In addition, when taking the factor into account that part of the exports transfer to Hong Kong first then sold to the EU, the EU share of exports in Fujian Province is higher than described above.
    With the rapid growth of exports in recent years, the battery of the importing country also faced a variety of trade and technical barriers. In 2003 China suffered a battery in the United States, “337 investigation”, another major exporter of this year. The EU has put forward higher battery technology standards, technical barriers to the new EU exports will have a great impact on battery.It is known that the European Commission issued notification for battery directive on February 3 this year to the WTO Committee on Technical Barriers to Trade TBT.

    New standards from the EU, China battery products in the mercury content of control can achieve the EU’s requirements, but at the cadmium and lead content the two indicators are far away from the EU’s standards. To adapt to the new directive we should increase the detection of harmful substances and the cost of finding alternative materials, the use of alternatives accordingly requested the manufacturing process and business-related equipment to improve production processes.

    Fuzhou Customs concerned that the current EU battery directive TBT notification is in the two-month comment period, as a WTO member, China has enjoyed the rights of notification to comment on the foreign . The domestic enterprises should actively put out their reasonable idea on the new unreasonable EU directive and try your best to reduce the Technical Barriers riskthe in the process of exporting battery.

           Uninterruptible power supply (UPS) battery usually use 3 to 5 years.  Expectant life depends on

    many factors, including the use of battery (equipment must be battery-powered model ) and other

    environmental factors. Here are some principles to ensure your equipment reach the longest

    expectant life:
    1. To ensure that your APC UPS Store in a cool, dry and ventilated place. Ideally,  the

    temperature of UPS’s location should be no higher than 24 degrees Celsius. Meanwhile, for

    ventilation purposes, you need to leave a reasonable amount  about 1-2 inches of space on each

    side for air circulation.
    2. Every year, only when necessary that 1 to 2 times UPS run time for calibration. Sometimes, you

    can perform run-time calibration to verify whether your running time is sufficient. However, the

    frequent implementation of run-time calibration will reduce the APC battery’s expectant life.
    3. Do not store the battery APC for a long time. The new battery can be stored for 6-12 months.

    After this time, you should use the battery as soon as possible, otherwise they will lose their

    large storage capacity.The used batteries will not be recommend to store.
    4. The load should not exceed 80% of the rated capacity of UPS equipment , as this would result in

    reduced run time. When the load increases, the running time will be correspondingly reduced. If

    the power can not supply fully, the UPS will soon run out and the release of its battery charged,

    which will reduce the battery expectant life. Note: To ensure longer battery run time, don’t

    connect the laser printer to the UPS backup battery socket. To ensure that laser printers use the

    “Surge only” outlet ( the appropriate model). For those who have no “Surge only” outlet , they

    would be proposed connecte the laser printer to a separate APC surge suppressor
