Presumably we all know that BYD vehicels is made up of iron phosphate batteries, and in this area has persisted for a long time, but recently, BYD has issued a statement, the content make people surprised.
The statement said that from next year, BYD will use ternary batteries for all parts of the passenger car, and BYD will expand in Qinghai next year a battery factory with 10Gwh of ternary battery capacity.
The announcement came as a surprise to the people, who had previously touted the iron phosphate battery as a highly secure, rich source of raw materials and easy to control. At the same time, the three-cell battery expressed a great disdain, said the three-cell battery security is poor, with great security risks.
However, from now on, BYD's attitude has changed a lot, the reason may be that the iron phosphate battery is not going to go on, now I think of the ternary battery. Look at what you did before. But there is nothing wrong with it. The courage of BYD to turn back in time is commendable.
The so-called ternary battery refers to the cathode materials using Ni-co-mn-Li or Ni-co-al-acid lithium lithium battery, which is characterized by low temperature, high energy density, high charging efficiency, good cycle life. Compared with lithium iron phosphate battery, its average energy density can be increased to $number, but its biggest drawback is the poor safety.
However, with the policy of driving (subsidies) and the continuous improvement of technology, the safety of ternary batteries will be further enhanced, from the market prospects, the development of space is still very large.
