Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.

The Massachusetts Institute of Technology (MIT) has developed a scalable bulk energy storage solution with chemical with inexpensive, abundant precursors: cement, water, and carbon black. Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength.

Georgia Institute of Technology researchers used aluminum foil-based negative electrodes with engineered microstructures in an all-solid-state lithium-ion cell configuration. They have reported hundreds of stable cycles with practically relevant areal capacities at high current densities.

Nuvola Technology says it has developed a direct deposition polymer separator technology that can eliminate the primary cause of lithium-ion battery fires.

First Solar has agreed to pay $38 million to buy Swedish manufacturing startup Evolar AB, as it seeks to expand development of high-efficiency tandem PV tech.

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.

A scalable thermal energy storage prototype system that combines the best latent and sensible heat transfers is now market-ready after three years of testing. It consists of engineered cementitious materials and thermosiphons in a combination that enables fast, efficient thermal performance at low cost.

Low participation rates for vehicle-to-grid (V2G) tech of just 12% to 43% are needed to provide short-term grid storage demand throughout the world by as early as 2030, according to a group of Dutch and U.S. researchers.

NOMAD Transportable Power Systems (NOMAD) has started offering plug-and-play, utility-scale mobile energy storage systems. There are three versions – 2 MWh, 1.3 MWh, and 660 kWh – with a patent-pending docking platform.

The New York City authorities have determined that a lithium battery in an unspecified micromobility device triggered a recent high-rise fire that injured dozens in Manhattan.
