Which lithium iron phosphate battery or ternary lithium battery has the higher energy density?

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. Energy density of BYD lithium iron phosphate battery: At present, the single energy density of BYD lithium iron phosphate battery pack is 150Wh, and BYD plans to continue to increase the energy density to 160Wh. In addition to lithium iron phosphate batteries, BYD is also developing ternary lithium batteries at the same time. If the technology of ternary lithium batteries is combined with lithium iron phosphate batteries and some adjustments are made to the original practice of using graphite as a negative electrode material, then around 2020 , BYD plans to increase the single energy density of lithium iron phosphate battery packs to 200Wh. 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 its technology is at the leading level in China. Previously, there were rumors that BYD 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.
