GM and LG Energy Solution are investing $1 billion to mass-produce advanced lithium manganese-rich (LMR) battery cells at their Spring Hill, Tennessee plant by 2028. This move aims to deliver 33% higher energy density than LFP at the same cost for large EVs, marking a strategic departure from European LFP investments.
Donut Lab's solid-state battery endured damage testing, failing to ignite but losing 55% of its charge capacity and experiencing a 17% thickness increase. The company highlights its "graceful failure" safety, yet independent verification for key claims like 100,000 cycles and 400 Wh/kg energy density remains absent.
Seattle-area startup Homeostasis is converting captured industrial CO2 emissions into high-performance graphite for batteries. This innovative process addresses both climate concerns and the critical global demand for battery materials, particularly amid geopolitical shifts affecting supply chains. The company recently secured funding and a strategic partnership with Saudi Aramco's LAB7 to scale operations.
Finnish startup Donut Lab has released the first independent test results for its production-ready, solid-state battery. Conducted by the state-owned VTT Technical Research Centre of Finland, the evaluation focused on charging speed and the battery's thermal behavior. This disclosure aims to address skepticism surrounding Donut Lab's claims of a major battery breakthrough.
