Separator tech to prevent battery fires
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 acquires perovskite specialist Evolar
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 scraps development of Sion solar cars
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.
Thermal battery offers fast, efficient performance at low cost
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.
EV batteries alone could satisfy short-term grid storage demand
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.
U.S.-made mobile lithium-ion batteries for utility-scale market
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.
Lithium battery triggers New York high-rise fire
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.
Novel redox flow battery paves way for low-cost storage
Researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.
The mobility rEVolution: PG&E obtains first V2G export rate for commercial EVs in US
PG&E has secured approval to set up a vehicle-to-grid (V2G) export compensation mechanism for commercial EV charging customers in California. Sono Motors is debuting its Sion solar electric vehicles in the US market, while Toyota and Jera are installing innovative second-life battery systems in Japan.
Mango Power unveils home and portable battery system
Mango Power has developed a 3.5 kWh battery system that can be expanded up to 14 kWh. The product features LFP battery cells from CATL and can be charged through AC wall outlets, with solar panels, or via electric-vehicle chargers.
