US researchers have developed a new lithium-air battery with solid electrolyte and the potential to reach a record energy density that is nearly four times that of lithium-ion batteries. The test cell demonstrated stability over 1,000 charge and discharge cycles.

Sono Motors, a solar electric-vehicle manufacturer in Germany, has terminated its Sion passenger car development program, as it has failed to secure enough funding to support pre-series production. It says it will now focus exclusively on retrofitting and integrating its patented solar technology into third-party vehicles.

CATL’s new lithium pricing structure gives Chinese original equipment manufacturers (OEM) an effective discount of more than 20%. It is making the move to win more orders amid a slowdown in the electric-vehicle market and the ongoing efforts of cell manufacturers to secure raw materials.

US-based Sakuu has announced that it has successfully 3D printed solid-state batteries in custom shapes and sizes at its battery pilot line facility in Silicon Valley, California.

Enteligent’s new charger, which debuted at Intersolar North America this week, is powered by the sun and eliminates DC-to-AC power conversion.

There is currently no widely accepted test methodology to assess the safety of second-life lithium-ion batteries (LiBs). However, a UK government study reveals two opposing views on their safety, raising concerns over whether such devices should be deployed in homes under any circumstances.

A new research paper proposes an optimal planning technique to identify the locations and sizes of electric-vehicle (EV) charging stations with controlled charging and hybrid wind and PV systems in a multi-microgrid.

Last year was another landmark 12 months for energy storage, with all indicators pointing to a massive surge in demand. Supply chain instability and inflation saw battery prices rise but the industry demonstrated an ability to swiftly react to geopolitical developments. We look at five trends driving the market.

Singapore-based VFLowTech is manufacturing compact, scalable vanadium redox flow batteries with 24/7 operation over lifespans of 25 years. It is now setting up a 200 MWh production line, with plans to scale up the production of modular, long-duration storage solutions.

The new EU Batteries Regulation is a blueprint for product legislation, regulating the whole life cycle of batteries in the European Union. Advanced rechargeable and lithium batteries association Recharge says successful implementation of the new regulation requires the prioritization of safety, information reliability, feasibility, market surveillance, and enforcement.
