Improving high-energy lithium-ion batteries with carbon filler
www.solarenergyconnect.com

Washington DC (SPX) Nov 11, 2020 Lithium-ion batteries are the major rechargeable power source for many portable devices as well as electric vehicles, but their use is limited, because they do not provide high power output while simultaneously allowing reversible energy storage. Research reported in Applied Physics Reviews, by AIP Publishing, aims to offer a […]

Predicting the slow death of lithium-ion batteries
www.solarenergyconnect.com

Stanford CA (SPX) Sep 15, 2020 Batteries fade as they age, slowly losing power and storage capacity. As in people, aging plays out differently from one battery to another, and it’s next to impossible to measure or model all of the interacting mechanisms that contribute to decline. As a result, most of the systems used […]
