Associated with the Korean group LG Chem in a new technology called Ultium, the American automobile group General Motors has almost completed the development of a new generation of battery with an almost unlimited lifespan.
At a conference with group investors, GM vice president Doug Parks said a new cell capable of lasting up to a million miles (1.6 million kilometers) will be there soon. The GM official did not give details on the new battery, but said that several teams were working on the subject as well on ancillary features such as ultra-fast charging, cobalt-free electrodes and solid state electrolytes.
General Motors is not the only one interested in these new extended life batteries. Tesla has similar goals and is set to announce big innovations on a battery day. Initially planned for May, it was postponed to June.
A factory in Ohio
Beyond its R&D work, General Motors continues to advance on its new generation of cells. Called Ultium and developed in partnership with LG Chem, it will display a low Cobalt content thanks to new chemistry. Called to succeed the current NCM (Nickel-Cobalt-Manganese), the NCMA makes it possible to replace cobalt by aluminum.
The new cell will be produced in a factory operated by Ultium Cells, a joint venture between General Motors and LG Chem. Located in Lordstown, in the US state of Ohio, it has barely started construction.
