A day when sodium-ion chemistry crossed into European GWh territory, Argonne found the right coat for sulfide solid electrolytes, perovskite-silicon hit 31% without indium, and California's battery fleet quietly ran 44% of the state's evening grid.
CATL's Tener Sodium cells will fill 5 GWh of European grid storage through a partnership with Dutch integrator Alfen, installations beginning in 2027. The chemistry's 15,000-cycle rating is doing a lot of the economic heavy lifting.
Combining computational screening with lab validation, Argonne researchers pinned magnesium oxide as a promising ultrathin coating for sulfide-based solid electrolytes — it keeps lithium ions moving while blocking electron leakage, which is exactly the job description.
An international team backed by Monash University achieved certified 31% efficiency in a commercially sized perovskite-silicon tandem mini-module, using reactive plasma deposition to replace indium — the supply-constrained transparent conductor standard panels depend on.
The America's Consortium for Electric Skyways (ACES) will standardize interoperable charging across 250+ US aviation sites by 2030, with Macquarie providing capital — a bet that eVTOL needs a charging network before the aircraft, not after.
Kazakhstan's president met CATL co-chairman Pan Jian to discuss siting Central Asia's first EV battery plant in the country — a conversation that mixes lithium resource access with geopolitical positioning, likely in that order.
SEIA's H1 2026 data shows solar and storage made up 91% of new US grid capacity added in Q1; on July 9, California's battery fleet discharged nearly 13 GW — covering 44% of evening demand — followed by a 23 GW solar generation record the next day.
Oman is building a 6 GW integrated solar cell and module facility in Sohar Freezone as part of a $1.74B strategic investment package — a downstream manufacturing bet from a country that still exports oil.
