Cutting battery demand could reduce emissions more than cleaner manufacturing, study finds

A study suggests cutting demand for electric-vehicle batteries may reduce greenhouse-gas emissions more than improving manufacturing processes. The research team analysed lithium-ion battery emissions for EVs and energy storage systems through 2050, projecting demand could rise as much as 20-fold and supply-chain emissions about 10-fold. Supply-chain measures could cut the per-battery footprint 34 percent by 2050, while demand-management strategies could cut 2024-2050 emissions by 6.0 to 7.2 billion tonnes of CO2 equivalent.

Thermal runaway detection and robot reconnaissance rollout speeds up to prevent battery fires

Industry is widening responses to lithium battery fires by deploying unmanned reconnaissance and expanding detection beyond visible flames. Thermal runaway is hard to spot in advance because voltage and temperature change little until just before it occurs, and remaining batteries can run away again after a fire is put out. Off-gas sensing is being tested as an early-warning method, while robots are used to inspect sites after extinguishing. Overseas standards are beginning to require off-gas monitoring.

GM\'s secret weapon to lower EV prices: battery development time cut in half

General Motors has built a battery cell development centre at its Warren campus in Michigan to help lower electric vehicle prices. The facility is designed to validate lab-developed cells ahead of mass production and optimise manufacturing processes. GM plans to speed development and cut costs as battery packs account for 30 to 40 percent of total EV cost. The centre will first pilot lithium manganese-rich prismatic cells, with test production in the fourth quarter and mass production planned for 2028.
