Stanford scientists identify new Li-B-S solid electrolyte materials that boost lithium-ion battery performance

Green Car Congress

The low-cost materials—made of lithium, boron and sulfur—could improve the safety and performance of electric cars, laptops and other battery-powered devices, according to the scientists. Most lithium-ion batteries today use a liquid electrolyte that can combust if the battery is punctured or short-circuited.

Stanford team proposes new design strategy for electrolytes for lithium metal batteries

Green Car Congress

Stanford University scientists have proposed a design strategy for electrolytes that enable anode-free Li metal batteries with single-solvent single-salt formations at standard concentrations. A lithium metal battery can hold about twice as much electricity per kilogram as today’s conventional lithium-ion battery. Battery500.

Gen 2 low-cost flywheel-based Torotrak KERS for buses en route to production in mid-2016

Green Car Congress

The KERS captures the kinetic energy that is normally wasted when the bus is braking and stores it in a steel and carbon fibre flywheel weighing 8.5kg and spinning at up to 30,000 rpm. The process of capturing, storing and releasing energy back to the wheels is fully automated, giving a high quality driving experience.
