Stanford study finds charging Li-ion cells at different rates boosts the lifetimes of EV battery packs

Green Car Congress

Stanford University researchers have devised a new way to make lithium-ion battery packs last longer and suffer less deterioration from fast charging. Related research has centered on single lithium-ion cells, which generally don’t lose charge capacity as quickly as full battery packs do. —Simona Onori. Resources.

Power-to-gas trial to inject hydrogen into Australia’s gas grid; A$5M award to AquaHydrex

Green Car Congress

The Australian Renewable Energy Agency (ARENA) announced a trial for a new type of electrolyzer which could see excess renewable energy stored in the gas grid and used to decarbonize Australia’s gas supply. Storing renewable energy directly in the gas network was a logical first route to market for the invention.

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. The researchers focused mainly on the favorable cost-performance comparisons between their sodium-ion battery and lithium. —Lee et al.
