Advantages of lithium iron phosphate batteries
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in most lithium-ion batteries at present.
Improvements in safety performance
The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat like lithium cobalt oxide or form strong oxidizing substances, so it has good safety.
Good high temperature performance
The electric heating peak of lithium iron phosphate can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.
Wide operating temperature range (-20C--+75C), with high temperature resistance, the electric heating peak of lithium iron phosphate can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.

High capacity
The current maximum charging power is 120kW, and it will reach 350kW in the future. The charging time is reduced from 40 minutes to less than 15 minutes, providing a better user experience. At the same time, high-power wireless charging technology will also be gradually applied. In the future, it will even be possible to charge while walking, making the use of new energy vehicles more convenient.

no memory effect
Rechargeable batteries often work under the condition of being fully charged, and the capacity will quickly drop below the rated capacity. This phenomenon is called the memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be used at any time without having to discharge it before charging.
light weight
The volume of the lithium iron phosphate battery with the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.
Environmental friendly
The battery is generally considered to be free of any heavy metals and rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certification), non-polluting, in line with European RoHS regulations, and an absolute green battery certificate. Therefore, the reason why the lithium battery is favored by the industry is mainly due to environmental protection considerations. Therefore, the battery has been included in the "863" national high-tech development plan during the "Tenth Five-Year Plan" period and has become a key project supported and encouraged by the state. With China's entry into the WTO, the export volume of China's electric bicycles will increase rapidly, and electric bicycles entering Europe and the United States have been required to be equipped with non-polluting batteries.
Comparison of power batteries
At present, the most promising cathode materials for power lithium-ion batteries are mainly modified lithium manganate (LiMn2O4), lithium iron phosphate (LiFePO4) and nickel cobalt lithium manganate (Li(Ni,Co,Mn)O2) ternary Material. Nickel-cobalt lithium manganate ternary material is generally considered to be difficult to become the mainstream of power lithium-ion batteries for electric vehicles due to the lack of cobalt resources, high nickel and cobalt formation and large price fluctuations, but it can be combined with spinel manganic acid. Lithium is used in combination within a certain range.
Industry application
Carbon-coated aluminum foil brings technological innovation and industrial improvement to the lithium battery industry
Improve the performance of lithium battery products and improve the discharge rate
With the increasing requirements of domestic battery manufacturers for battery performance, new energy battery materials are generally recognized in China: conductive materials & conductive coated aluminum foil/copper foil.
Its advantages are: when dealing with battery materials, it often has good high-rate charge-discharge performance and large specific capacity, but has poor cycle stability and serious attenuation, and has to make a choice.
