Lithium batteries is becoming a global R & D hot spot for four years after exploding 215-fold

The current hybrid cars use nickel-metal hydride battery technology major, but the nickel-metal hydride battery HP Laptop Battery a number of technical properties such as energy density, charge and discharge speed is close to theoretical limits. The lithium battery has energy density, high-capacity, no memory, etc., are various car makers and battery manufacturers unanimous endorsement of the current national focus on R & D is the lithium-ion batteries.

According to the different cathode materials, lithium batteries are lithium cobalt oxide, lithium manganese oxide, ternary materials, and four kinds of lithium iron phosphate. Lithium iron phosphate which is the best hybrid vehicle using lithium cathode materials. At present, China's car prices introduced models in purely electric vehicles, power batteries are lithium batteries, Chery, BYD are using lithium iron phosphate.

The advantages and disadvantages of four commonly used lithium batteries glance

Evaluation

Lithium iron phosphate

Because of the high discharge power, low cost (about 18 ~ 30 yuan / ton), fast charging and long cycle life (over 1000),Compaq Presario R3000 battery (Compaq r3000 battery) in high-temperature environment, the stability of the high heat (temperature above 300 degrees have potential safety problems) has a good safety performance.

Best

Ternary material

Ternary material better combines the advantages of the three nickel-cobalt-manganese to make up for their shortcomings, with high specific capacity, low cost, loop performance, stability, security, good performance and so on.
