A low-cost and effective additive for polymer electrolytes in rechargeable all-solid-state batteries
All-solid-state batteries are the next logical step to improve upon the Li+-ion battery for energy storage in portable electronic device. With the desire to advance the per charge driving range of electric vehicles, improvements to the volumetric and gravimetric energy density of the battery packs must be made. The most-direct method of improving the...

A new rechargeable lithium battery cathode architecture
Current Li+-ion batteries require electronically conductive additives within the cathode to maintain electrical contact between the small dispersed active cathode particles responsible for the energy storage reactions in the cell. Additionally, they require a polymer binder to hold the conductive additive and active material together. These two additional...

Artificial SEI for a stable lithium metal anode in rechargeable batteries
Background Alkali metal anodes for rechargeable batteries suffer from dendrite formation, which subsequently causes electrical shorting and thermal runaway for the battery. A technology developed by researchers at The University of Texas at Austin stabilizes the anode-electrolyte interface such that stable alkali-metal plating/stripping is achieved...
