As the world decarbonizes to combat climate change, one of the moves is switching to electric vehicles that run on batteries instead of fossil fuels. That means there will soon be a lot of explosive batteries that need disposing of. It’s estimated that by 2025 cars will account for 90%...

The global demand for lithium is continuously increasing. The energy-critical element is used to make rechargeable batteries, one of the core components of an electrified world. Electric vehicles (EVs) use them and power plants for storing energy from renewables when electricity demand is low. Lithium is the choice element for...

Scientists at the Dornsife College of Letters, Arts, and Sciences of USC have demonstrated a safe, inexpensive, eco-friendly, long-life, all-iron redox flow battery with a coulombic efficiency of 97.9% thanks to pH, functional electrolyte additives, and elevated temperature. coulombic efficiency is the ratio of charge extracted against charge put in...

Toyota Motor Corporation is collaborating with Kyoto University researchers to develop new batteries for future electric vehicles (EVs). They recently announced that the next-generation battery technology they’ve been working on could cram more energy into a more lightweight and compact package than today’s standard lithium-ion (li-ion) batteries. The group’s fluoride-ion...

A team from the Cockrell School of Engineering at the University of Texas at Austin have developed a new kind of battery that mixes the best of both worlds of liquid- and solid-state batteries. The design is the first all-liquid metal battery that can work at room temperature and is...

Battery development is crucial for clean energy growth and the uptake of electric cars. They need to become safer, cheaper, and able to hold more energy for longer. However, improving batteries relies on a trial and error process, which is very slow. Fortunately, machine learning may be able to help,...

Coal-fired power stations could run fossil-fuel-free by switching from coal to blocks. The thermal “lego blocks” look like a brick or paver. They contain a metal alloy that can efficiently store power as thermal energy. Researchers at the University of Newcastle developed them, and the patented Miscibility Gaps Alloy (MGA)....
