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

Green Car Congress

Stanford University scientists have identified a new solid-state Li-ion electrolyte predicted to exhibit simultaneously fast ionic conductivity, wide electrochemical stability, low cost, and low mass density. log scale) of several known solid Li-ion conductors and the predicted values for the best Li?B?S Sendek et al.

New electrode material for solid-state batteries improves performance

Green Car Congress

An all-solid-state lithium battery using inorganic solid electrolytes requires safety assurance and improved energy density, both of which are issues in large-scale applications of lithium-ion batteries. However, they have never been applied to all-solid-state batteries.

New hydrogen storage material could enable smaller, cheaper, more energy dense systems for vehicles; Kubas binding

Green Car Congress

It could enable the design of tanks that are smaller, cheaper, more convenient and energy dense than existing hydrogen fuel technologies, and significantly out-perform battery-powered vehicles. The KMH-1 material also absorbs and stores any excess energy so external heat and cooling is not needed.

Stanford study quantifies energetic costs of grid-scale energy storage over time; current batteries the worst performers; the need to improve cycle life by 3-10x

Green Car Congress

Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS). The five battery technologies fared much worse. —Charles Barnhart. PHS followed at 210.

Industry study finds lead-acid to remain most wide-spread automotive energy storage for foreseeable future; new chemistries continue to grow

Green Car Congress

Hybrid vehicles , including advanced micro-hybrid, mild-hybrid and full-hybrid vehicles rely on the battery to play a more active role, with the energy stored from braking used to boost the vehicle’s acceleration. In full-hybrid vehicles, the stored energy is also used for a certain range of electric driving.
