A KIST-IAE team engineered a tungsten diselenide catalyst that achieved over 550 stable cycles in lithium-air batteries, outperforming conventional catalysts and advancing a technology with ten times the energy density of lithium-ion.

Peak Energy and RWE Americas have deployed the first sodium-ion battery system on the MISO grid in Wisconsin, marking a milestone for the cheaper, cobalt-free chemistry in the US.

BYD has launched its second-generation Blade Battery and a 1,500 kW FLASH Charging network that can take a compatible EV from 10 to 97 percent in nine minutes, with plans to deploy 20,000 stations across China by year-end and begin overseas rollout.

A 300 MW Form Energy iron-air battery paired with 1.6 GW of wind and solar will power Google's new Pine Island data center, marking the largest energy storage project ever announced by capacity.

CATL and BYD are mass-producing sodium-ion batteries for EVs and grid storage in 2026, driven by soaring lithium prices and abundant raw materials, while the West struggles to keep pace.

A novel covalent organic framework electrolyte solves calcium-ion transport problems that have stalled the technology for decades, opening a path to cheaper, more abundant battery chemistry.
