JAIST packs more juice into Li-ion batteries with silicon anodes and polymeric coatings

Although silicon anodes could greatly boost the capacity of Li-ion batteries, their performance rapidly degrades with use. Polymeric coatings can help solve this problem, but few studies have explored the underlying mechanisms. In a recent study, scientists from the Japan Advanced Institute of Science and Technology (JAIST) investigated how a poly(borosiloxane) (PBS) coating stabilizes the… Read more »
