China-based TAILG has revealed its new sodium-ion battery technology. The company’s luxury e-bikes will be the first to feature its sodium-ion batteries, and they will initially be available in China.

The US Department of Energy’s (DoE) Argonne National Laboratory and Idaho National Laboratory will carry out demonstration projects to validate long-duration energy storage tech developed by German manufacturer CMBlu Energy. The collaborative project is designed to improve microgrids in cold climates and make fast charging of electric vehicles more affordable in underserved communities.

Germany-based BMZ Group has unveiled a plug-and-play, AC-coupled, outdoor commercial battery energy storage solution that can store from 68 kWh to 204 kWh of energy. The 10-foot container comes with an integrated inverter and a 10-year warranty.

Two workers have died in separate accidents at Northvolt’s battery gigafactory in Sweden in recent weeks, with a technician succumbing to burns after an explosion on a production line and a construction worker killed by a falling fork stand. pv magazine has learned that the equipment that caught fire was not a part of the battery manufacturing process.

KPIT, an India-based automotive software and engineering solutions supplier, has unveiled its proprietary sodium-ion battery technology, and is now on the lookout for manufacturing partners. Ravi Pandit, chairman of KPIT, tells pv magazine, that that the company has developed multiple variants with energy density ranging from 100 Wh/kg to 170 Wh/kg, and potentially reaching 220 Wh/kg.

Enerpoly, a Swedish startup that produces zinc-ion battery storage systems with durations of two to 10 hours, plans to scale production up to 100 MWh per year by 2026.

Fourth Power, backed by Bill Gates’ venture firm, has developed high-density thermal energy storage (TES) based on thermophotovoltaic (TPV) cells. The tech, which is reportedly 10 times cheaper than lithium-ion batteries, is based on the US company’s patented liquid metal heat transfer system.

Nilar, a Swedish producer of nickel metal hydride batteries, has filed for insolvency and is now looking for a new owner.

Solhyd, a KU Leuven spinoff, is refining its technology to reach megawatt-scale production of hydrogen-producing solar panels with a €6 million ($6.5 million) investment from a consortium of Flemish investors.

The new cobalt-free battery yields about 60% greater energy density than conventional lithium-ion batteries for an equivalent weight and volume and sustains unprecedented 1,000 cycles.
