Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. A paper on the work is published in Nature. —Pang et al. —Donald Sadoway.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

The California-based Hyperlight Energy will be piloting an installation where they plan to use existing oil wells as solar thermal wellsprings, with the stored energy being converted back to clean electricity when required. Thermal energy storage is a known low-cost, low-risk approach for storing solar energy in the form of heat,” adds Codd.

Each system comprises electronic components that can be used with a variety of batteries and motors and installed on conventional medium- and heavy-duty chassis, modifying them into all-electric battery operated vehicles that have no tailpipe emissions. Currently, these powertrains are primarily installed in shuttle buses and delivery trucks.
