Super-fast, long-life aqueous rechargeable zinc battery

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.

Rapid-charging solid-state battery moves toward commercialisation

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.

Pumped heat energy storage seeks to demonstrate commercial readiness

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 to build 4 GW solar farm in Nueva Ecija, Bulacan provinces

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.

Weekend read: Hype and hope for solid-state batteries

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.

Optical microscopy technique to study prevention of battery failure

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.

Research team unveils high-efficiency coloured BIPV panels

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%.

Universal method to improve lifespan of lithium-ion batteries

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.
