Integrals Power, a UK-based battery materials company, has announced that its lithium-manganese-iron-phosphate (LMFP) cells have passed the 1,000-cycle milestone in ongoing durability testing by QinetiQ.
A testing programme has been ongoing for more than five months, and the company said the 1,000 charge and discharge cycles were accumulated at 1C rate.
The company said its cell materials include 80% manganese content to increase energy density compared to conventional lithium-iron-phosphate (LFP) batteries, but at less cost than nickel-manganese-cobalt (NMC) chemistries.
The LMFP material, which QinetiQ has made into pouch cells, is claimed to have retained more than 80% of its original capacity.
Integrals said it is developing the second-generation of its LMFP material whilst waiting for the next round of test results.
The company said it is expecting the cycle life and retained capacity to be improved, with 30% less internal resistance in the cell.
The LMFP material was produced at the firm’s UK pilot plant, with raw materials sourced from Europe and North America.
Behnam Hormozi, founder and CEO, Integrals Power, said, “We believe that LMFP cells will enable EV battery packs to become less costly and less carbon-intensive to manufacture while offering the range, the long life, and the safety that EVs and other applications need to go mainstream in global markets. These latest results demonstrate to our customers that they can do exactly that, and as QinetiQ continues the test programme, we’re confident that the cells will still show impressive capacity retention as we progress to the next milestone.”
