According to "Made in China 2025", the development plan of power battery is defined: by 2020, the battery energy density will reach 300Wh/kg; by 2025, the battery energy density will reach 400Wh/kg; by 2030, the battery energy density will reach 500Wh/kg. At present, what level does China's battery power lithium battery energy density reach?
BYD: currently, BYD's lithium iron phosphate battery has a mono-cell energy density of 150Wh, and BYD plans to further increase the energy density to 160Wh. In addition to the lithium iron phosphate batteries, BYD has developed simultaneously in the ternary lithium batteries, and if combine the technology of ternary lithium battery to lithium iron phosphate batteries, the original with graphite as the cathode material for some adjustment, so around 2020, BYD plans to the energy density of lithium iron phosphate battery monomer the ascent to 200 wh.
In addition, in the follow up of the ternary batteries, BYD's three Yuan batteries have production conditions, the energy density reached 200wh/kg. BYD ternary target is 2018 battery energy than 240wh/kg, 300wh/kg in 2020.
Walter: production of 32650 cylindrical power batteries, lithium iron phosphate monomer energy density reached 145wh/kg, the next goal is to achieve 160wh/kg; Three Yuan battery is the energy density of 200wh/kg, is expected to reach 300wh/kg level in 2020.
National battery: As early as 2013, the energy density of lithium iron phosphate and ternary battery monomer reached 160Wh/kg and 200Wh/kg. It is predicted that by the end of 2017, the energy density of lithium iron phosphate battery monomer will reach 180Wh/kg, PACK will reach 134Wh/kg, and the energy density of ternary battery will exceed 240Wh/kg.
Gateway power: In terms of energy density, the company has now mass-produced ternary soft-pack battery monomer specific energy of 210WH/Kg. On the basis of improving battery safety, it is estimated that the energy density of the company's soft-pack battery monomer can reach 300WH/Kg in 2020, and the Pack group can reach 220WH/Kg. The energy density of lithium titanate battery monomer reaches more than 110WH/Kg.
Smart energy: the energy density of the company's mass-produced power battery monomer can reach 220Wh/Kg, and the energy density of PACK can reach 140Wh/Kg. At the same time, the company's BMS system can achieve level 5 Protection, battery pack using lightweight materials and structural optimization.
BAK battery: in 2016, BAK ternary material power battery industry accounted for more than 30%, ranking first. At present, the energy density of BAK monomer cell is nearly 220Wh/kg, and it will be further increased to 300Wh/kg in the future.
CENAT: CENAT has been able to supply energy density 220Wh/kg cells in batches. System specific energy is larger than 130Wh/kg cells. At the same time, the process and technical levels have realized 250Wh/kg and 300Wh/kg as reserved product.
