Energy Dome has activated its first commercial-scale energy storage facility in Sardinia, Italy, with a capacity of 200 megawatt-hours, capable of powering approximately 18,000 homes for 10 hours. The company, founded in 2020 and based in Milan, plans to develop up to 30 gigawatt-hours of storage projects across five continents, leveraging its unique carbon dioxide battery technology that does not rely on specific geological formations. While the technology is estimated to be more cost-effective than lithium-ion for longer durations, it currently has only one operational plant and faces efficiency limitations compared to traditional batteries.

BYD Executive Vice President Stella Li said the company is in a "leading position" on solid-state battery technology and will release its first vehicle using the tech in 2027. This aligns with earlier statements from BYD battery subsidiary FinDreams, which said mass production of sulfide-based solid-state batteries would follow around 2030, with lithium iron phosphate batteries still used alongside them in lower-tier models.

Cornell University scientists created a process called Direct Electrode-to-Electrode Regeneration (DEER) that revives worn EV battery electrodes by chemically stripping excess solid electrolyte interphase buildup rather than shredding cells into raw materials. Treated electrodes recovered up to 95% of original capacity and degraded more slowly than untreated batteries, and a second treatment round restored capacity to 90% even after prior regeneration.

Laptops with trackpads that bulge or pop out are often showing a symptom of a swollen lithium-ion battery, which sits directly beneath the trackpad in most designs including MacBooks and Surface devices. Battery swelling happens when overcharging or physical damage triggers chemical reactions that release gas, pushing outward against internal components. Apple has previously run replacement programs for MacBooks affected by this exact issue.
