High rate discharge life

Ordinary cars last for decades, and an electric car's battery requires at least 3,000 cycles in 10 years. As a relatively expensive component, it is very important that the life is equivalent to the car. It is necessary to ensure the performance of the vehicle and to ensure the interests of the owner, so as to benefit the market. At present, the electric vehicles of the world's car companies, only BYD "Qin" listed last year has achieved the battery life warranty.

The life of the battery is also the cycle life, not the number given by the simple battery parameters. The cycle life of the battery is closely related to the cycle state of the battery, such as discharge rate, charge rate, temperature, and the like. Usually, the cycle life obtained from the battery laboratory data is obtained at a constant charge and discharge rate of 0.3 C at a constant temperature of 20 degrees. However, during the actual use of the car, the magnification and temperature are not constant. This is why, in general, whether it is a notebook, a mobile phone, or a battery of a battery car, the life in actual use is far less than the reason given by the manufacturer. The medium and small mileage pure electric and long-life dual-mode hybrid vehicles, because they have fewer batteries, will have higher discharge requirements and will have a greater impact on life. 

 Lithium iron phosphate is a new type of lithium ion battery electrode material. It is characterized by large discharge capacity, low price, no toxicity, and no environmental pollution. Countries around the world are competing to achieve industrial production. However, its tap density is low, affecting the capacitance. At present, the main production method is high temperature solid phase synthesis, and the product index is relatively stable.

The performance of lithium-ion batteries mainly depends on the positive and negative materials. Lithium iron phosphate as a positive electrode material for lithium-ion batteries has only appeared in recent years. The large-capacity lithium iron phosphate battery developed in China was July 2005. Its safety performance and cycle life are incomparable to other materials, which are the most important technical indicators of power batteries. 1C charge and discharge cycle life of 2000 times. Single cell battery overcharge voltage 30V does not burn, puncture does not explode. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series. To meet the needs of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price and long service life. It is an ideal cathode material for a new generation of lithium ion batteries.
