What is the energy density of a ternary lithium battery?

Ternary lithium battery energy density: 300Wh/kg energy density successfully broke through my country's ternary lithium battery and entered the era of high energy density 3.0. Recently, my country has made major breakthroughs in the development of high nickel cathode materials and power lithium-ion battery cells. Tianjin Lishen Battery Co., Ltd. has developed an NCA ternary high specific energy power lithium battery with an energy density of more than 300wh/kg. Industry concerns. In addition, in terms of the ternary lithium battery to be followed up, BYD’s ternary lithium battery has the conditions for mass production, and the current energy density has reached 200Wh/kg. The goal of BYD's ternary lithium battery is to reach 240Wh/kg in 2018 and 300Wh/kg in 2020. Industry insiders said that the current single energy density of ternary lithium batteries is close to the limit, and it is difficult to make a major breakthrough. To further increase the energy density of ternary lithium batteries, it is necessary to further increase the proportion of nickel in the battery. However, after the proportion of nickel in the battery is increased, due to the poor thermal stability of high nickel, the thermal reaction inside the battery will be very violent, and safety issues are worrying. Comparing the energy density of lithium iron phosphate batteries and ternary lithium batteries The energy density of lithium iron phosphate batteries is far less than that of ternary lithium batteries, but its safety is generally considered to be better than that of ternary lithium batteries. Let me talk about energy density first. At present, the subsidy standard for new energy vehicles depends on the energy density of the battery system. The specific policy is that when the energy density of the battery system exceeds 120Wh/kg, you can enjoy 1.1 times the subsidy, which is between 90Wh/ Only 1 times subsidy can be enjoyed between kg and 120Wh/kg. It is known that it is not difficult for the current lithium iron phosphate batteries on the market to achieve 90Wh/kg after improvement, but there are very few companies that can achieve 120Wh/kg. BYD has always been focusing on lithium iron phosphate batteries, and this technology is at the leading level in China. Previously, there were rumors that BYD had developed high-energy density lithium iron phosphate batteries with a capacity density of 150Wh/kg, which is comparable to ternary lithium The battery is almost equivalent.
