E-bike lifepo4 battery pack
Advanced technology to change the world
lithium iron phosphate as cathode (LIFEPO4 technology)
Due to the shortage of fossil fuels and environmental concerns, we re convinced that the green energy industry and related industries will become the main stream in the coming 30-50 years. This causes a strong demand of rechargeable batteries. However, the existing lithium ion cell systems including lithium cobalt oxide and lithium manganese oxide still suffer from low discharge rate, safety concern and short cycle life.
To solve those issues, Dr. John Goodenough and his team at University of Texas patented as potential cathode material LiFePO4 as a potential cathode in 1996. It is a very stable material due to the covalent P-O bonding which stabilize the fully charged cathode versus O2 release. scientists have developed the LiFePO4 battery using lithium iron phosphate as cathode to answer concerns in the battery for Electric Vehicles and other battery useages..
There are three types of lithium ion cells based on different cathode materials. They are lithium cobalt oxide, lithium manganese oxide and lithium iron phosphate types. Although lithium cobalt oxide cell has the advantage of high energy density, it suffers from safety concerns. Lithium manganese oxide cell has been evaluated for the application on high rate due to the better safety characteristics. However, its high temperature performance is the major drawback.
While Lithium iron phosphate cell has the best safety characteristics, long cycle life (up to 2000 cycles) and good availability. It is very suitable for high discharge rate occasions such as EV (including e-bike, electric scooter, and electric car), power tools, UPS and solar energy system. According to different applications, Liberty can modify the design of battery pack to provide the best solution to satisfy our customer' s needs.
