Tokyo University Scientists vastly improve capacity of sodium- and potassium-ion batteries

Electric Cars Report

Lithium-ion batteries (LIBs) are, by far, the most widely used type of rechargeable batteries, spanning numerous applications. Although LIBs deliver the best performance in many aspects when compared to other rechargeable batteries, they have their fair share of disadvantages.

New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. The same approach was also applied to design stable SEI layers for sodium and zinc anodes. Credit: Donghai Wang,Penn State.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.
