BYD electric car will consider use ternary lithium battery
July 7th, BYD released the visit record of investor, which issued BYD 2015 annual operation condition, how to treat with lifepo4 battery and ternary battery energy density, new energy car competitive advantages, how to build it's own brand etc.
Ask: how to treat the energy density of lifepo4 battery and ternary battery?
Answer: battery energy density depend on it's anode material, lifepo4 battery generally can reach 170wh/kg-175wh/kg, while ternary battery could reach much higher level, so undoubtly ternary battery energy density is higher than lifepo4 battery, but ternary battery will be much active which might result in heat dissipation out of control. according to its typical characteristics of each kind of battery, for insensitive car like electric bus and commercial car which has less requirement on size and weight, we will consider to use lifepo4 battery, otherwise we will consider to use ternary battery, such as PHEV.
