⚡GM and Redwood Partner on Sodium-Ion Energy Storage
Sodium-ion batteries could shake up grid-scale storage
TL;DR
GM is investing $900M to develop and commercialize new battery chemistries, including sodium-ion cells for energy storage. Sodium-ion batteries offer cheaper, longer-lasting alternatives but are bulkier than lithium-ion.
GM has committed $900 million to developing and commercializing new battery technologies, with a focus on sodium-ion chemistry tailored for grid-scale deployments. These batteries work similarly to lithium-ion but replace key materials to reduce costs and improve safety. Sodium-ion cells will be larger and heavier than their lithium counterparts, yet they promise significant cost savings over time. GM expects to cut about a year from the commercialization process, reducing upfront costs and maintenance expenses.
Key Points
GM committed $900 million to commercialize new battery chemistries, including sodium-ion cells.
Sodium-ion batteries work similarly to lithium-ion but swap out key materials for cost reduction and improved safety.
GM's first sodium-ion cells are expected in trial production at the Battery Cell Development Center by 2028.
Redwood Materials operates a microgrid using second-life EV packs, attached to a Crusoe data center in Nevada.
GM will sell lithium iron phosphate (LFP) cells to LG Energy Solution for use in energy storage systems.
Why It Matters
If you're involved in grid-scale energy storage projects, GM's sodium-ion battery plans could significantly impact your cost structure. Sodium-ion batteries offer cheaper and safer alternatives but require more space. Redwood Materials' microgrid setup with second-life EV packs is a real-world example of how these technologies can be integrated.
