Tohoku team develops new electrolyte to support rechargeable calcium batteries

Green Car Congress

Scientists from Tohoku University have developed a new fluorine-free calcium (Ca) electrolyte based on a hydrogen (monocarborane) cluster that could potentially realize rechargeable Ca batteries. High-energy-density and low-cost calcium (Ca) batteries have been proposed as ‘beyond-Li-ion’ electrochemical energy storage devices.

Georgia Tech team develops simple, low-cost process for oxide nanowires; superior separators for Li-ion batteries

Green Car Congress

Fabricated separators based on aluminum oxide nanowires enhanced the safety and rate capabilities of lithium-ion batteries. The dissolution process generates hydrogen gas, which could be captured and used to help fuel the heating step. One of the attractive applications may be separator membranes for lithium-ion batteries.

ANL fluorinated cation electrolyte could help enable high-performance, long-lasting Li-metal batteries

Green Car Congress

An electrolyte carrying fluorine in both cation and anion brings unprecedented interphasial chemistries that translate into superior battery performance of a lithium-metal battery, including high Coulombic efficiency of up to 99.98%, and Li 0 -dendrite prevention for 900 hours. The team’s new electrolyte offers many other advantages as well.

RPI researchers develop new aqueous Li-ion battery that improves safety without sacrificing performance

Green Car Congress

As the lithium-ion batteries that currently power most phones, laptops, and electric vehicles become increasingly fast-charging and high-performing, they also grow increasingly expensive and flammable. If you apply too much voltage to water it electrolyzes, meaning the water breaks up into hydrogen and oxygen. —Nikhil Koratkar.
