RICHLAND, Wash. - Dendrites - the microscopic, pin-like fibers that cause rechargeable batteries to short circuit - create fire hazards and can limit the ability of batteries to power our smart phones and store renewable energy for a rainy day.

Now a new electrolyte for lithium batteries that's described in Nature Communications eliminates dendrites while also enabling batteries to be highly efficient and carry a large amount of electric current. Batteries using other dendrite-limiting solutions haven't been able to maintain both high effi...
