The battery’s energy density is 15-20 percent above that of lithium iron phosphate batteries, but there’s little difference in the material costs, consistent with local media.

China’s largest power battery maker Contemporary Amperex Technology Co Ltd (CATL, SHE: 300750) appears to possess a large stockpile of new technologies waiting to be put to use.
CATL plans to mass produce lithium manganese iron phosphate (LMFP) batteries within this year, local media outlet LatePost reported today. The corporation announced its CTP (cell to pack) 3.0 Qilin Battery and teased condensed matter batteries late last month.
CATL, Sunwoda and Eve Energy’s LMFP batteries have passed interim tests within the first half of this year and are now sending samples to automakers for testing, consistent with the report.
In addition to these companies, BYD’s FinDreams Battery began purchasing materials in small quantities earlier this year, and its LMFP battery is currently within the internal development stage, the report said, adding that Gotion High-tech also revealed a patent associated with lithium manganese iron phosphate batteries in June, but there are not any clear plans for mass production.
These companies began depending on LMFP batteries because they can achieve a higher energy density than lithium iron phosphate batteries.
The theoretical energy density of LMFP batteries can reach up to 230 Wh/Kg, 15-20 percent above lithium iron phosphate batteries, but there’s almost no difference in the cost of the material, consistent with LatePost.
BYD had conducted related research in 2013, but it terminated the event of LMFP batteries in 2016 because of their low cycle life and high internal resistance at the time, consistent with the report.
Companies including CATL are now choosing to dope lithium ternary materials with LMFP materials to unravel the problem of low battery life and high internal resistance, which is that the “M3P battery” declared by CATL chairman Robin Zeng in the course of a roadshow in February, the report said.
On June 23, CATL officially unveiled its much-anticipated Qilin Battery, claiming a record-breaking volume utilisation rate of quite 72 percent, making it the very best integrated battery in the world today.
The battery can reach an energy density of 255 Wh/kg, easily allowing vehicles to realise a range of 1,000 km, CATL said at the time, adding that it’ll be in mass production by 2023.
Laterly, automakers as well as Li Auto (NASDAQ: LI, HKG: 2015), Hozon Auto’s Neta, and Geely’s Lotus all signalled at using the Qilin Battery.

Two days later, Zeng said at the Chongqing auto show on June 25 that additionally to solid-state and semi-solid-state batteries, CATL is additionally working on condensed matter batteries, which individuals have not heard of.
The joint advancement of the power battery chemistry system, structure, manufacturing, and business model innovation is what is going to drive the development of the new energy vehicle (NEV) industry, Zeng said at the time.

In addition to these, CATL announced its first-generation sodium-ion battery last year, saying it’s a slightly lower energy density than the current lithium iron phosphate battery, but has significant advantages in low-temperature performance and fast charging.
CATL has already started the industrialization layout of sodium-ion batteries and plans to make a basic industrial chain by 2023, the corporation said several times.
