General Motors (GM) partners to recycle electric car batteries

In partnership with an electric car battery and recycling company, Redwood Materials, General Motors (GM) announced that it will recycle battery scrap from two of its manufacturing facilities.

Redwood, created by Tesla co-founder and former chief technology officer J.B. Straubel, will handle all scrap from GM's Warren, Ohio, and Spring Hill, Tennessee, facilities.

The agreement, for recycling, more specifically, is signed between Redwood and Ultium Cells, a battery manufacturing joint venture between GM and the South Korean LG Energy Solution, an important supplier of lithium-ion batteries to automakers such as own GM, Audi and Mercedes-Benz.

The scrap that Redwood will process will include cathode and anode material, essential ingredients in lithium-ion batteries. The company will take the materials and turn them into battery materials that can then be sold back to its various partners to manufacture new electric vehicle batteries.

Redwood's main facility in Nevada is already receiving materials from Ultium Cells for recycling and processing. According to Redwood, even the most efficient battery cell manufacturers still produce scrap at an average rate of 5% to 10%.

Redwood Materials was founded in 2017 by Straubel. In addition to breaking down scrap from GM's battery manufacturing process, the company also recycles batteries for EVs from Tesla, Ford, Toyota, Nissan and several other companies;

After receiving batteries from its various partners, Redwood begins the chemical recycling process, in which it removes and refines the relevant elements, such as nickel, cobalt and copper;

On average, 95% of the main battery metals, after being refined, can be reintegrated into the new battery manufacturing process.
