Now Gotion High-tech has unveiled a new battery technology, which claims to be able to achieve a range of 1,000 km even without the use of expensive ternary materials.
Hefei, Anhui-based Gotion unveiled its L600 LMFP battery cells based on lithium iron phosphate (LFP) chemistry and a battery pack called Astroinno Battery at its 12th technology conference.
The L600 LMFP cells have an energy density of 240 Wh/kg, or 525 Wh/L. The cells support 4,000 cycles at room temperature and 1,800 cycles at high temperature.
A battery system based on the L600 LMFP cell could have an energy density of 190 Wh/kg, which is higher than the energy density of packs based on ternary chemistry systems that are in mass production now, Gotion said, adding that the new cell will be in mass production in 2024.
The energy density growth of mass-produced LFP cells has faced a bottleneck, and further improvements require chemical system improvements, so the LFP solution with manganese addition was born, said Cheng Qian, Gotion's executive president of international operations.
