(PhysOrg.com) -- Part of the headache of having to constantly recharge batteries is not just how often they need to be charged, but also the time it takes to charge them. In a new study, researchers have proposed a charging ...
(PhysOrg.com) -- Researchers have found that by replacing conventional graphite electrodes with silicon nanotube electrodes, lithium-ion batteries can store 10 times more charge.
Most existing lithium-ion batteries (LIBs) integrate graphite anodes, which have a capacity of approximately 350 milliamp hours (mAh) per gram. The capacity of silicon anodes is almost 10 times higher than that of their graphite ...
(PhysOrg.com) -- One promising modification to next-generation rechargeable Li-ion batteries involves using Si-alloy anodes instead of graphite, which is currently the most common anode material. Many battery manufacturers ...
Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to a high-impact and long-sought advance for rechargeable batteries: replacing the graphite anode with ...
