An international group of researchers has demonstrated an aqueous zinc battery with excellent performance in terms of capacity, rate capability, specific energy, and output voltage. The supercapacitor-battery hybrid device has also shown unprecedented cycling stability 99.2% capacity retention after 17,000 cycles at 100% depth of discharge.

US researchers have developed a new solid-state lithium-metal battery, and China’s SVOLT has started producing prototype solid-state cells. Toyota, meanwhile, has revealed plans to invest billions of dollars in battery production.

Southwest Research Institute (SwRI) has commissioned a first-of-its-kind pilot plant pumped heat energy storage demonstration facility with tech from US startup Malta. Its 10-150+ hour energy storage technology is said to be applicable in a range of grid-scale applications.

Solar Philippines, a Manila-based PV module manufacturer and project developer, is looking to secure at least 2,500 hectares of land to expand its 500 MW flagship solar project to 4 GW.

Hype and hope for solid-state batteries (SSBs) continues to grow as industries from automotive to storage bet big on the technology. Leading battery manufacturers and a roll call of start-ups are jostling to get from lab to fab. The reality of SSBs is in question though. As Marija Maisch reports, the window of opportunity for the decades-old technology to make the next big step toward commercialisation is now.

Researchers at the University of Cambridge have examined one of the fastest-charging anode materials by using a low-cost, lab-based optical microscopy technique. Their findings showed that particle fracture, which can reduce the storage capacity of a battery, is more common with higher rates of delithiation and in longer particles.

Researchers in China have reported a colourisation strategy for solar based on photonic glass. They created solar panels that took on blue, green, and purple hues, while only dropping the efficiency of power generation from 22.6% to 21.5%.

Researchers at the Gwangju Institute of Science and Technology (GIST) have developed a broadly applicable and versatile post-electrode-engineering process. It can be applied to a range of conventional anodes to improve their stability.

Scientists in Japan have developed a novel metal-organic, framework-based magnesium ion conductor with superionic conductivity, even at room temperature.

Researchers in Russia have developed a new sodium-vanadium phosphate fluoride powder. It has a particular crystal structure that provides superior energy storage capacity in the battery cathode.
