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 »

Hong Kong researchers propose novel cathode design for Li-S batteries
A team led by Professor Zhao Tianshou of the Hong Kong University of Science and Technology has proposed a novel cathode design concept for lithium-sulfur (Li-S) batteries. Li-S batteries are regarded as attractive alternatives to Li-ion batteries. They are known for their high energy density, while their major component, sulfur, is abundant, light, cheap and… Read more »
Sunstone Engineering’s new battery welding system paves way for copper and nickel tab welding
Sponsored by Sunstone Engineering Sunstone’s new Omega PA250i battery welding system can do what other welders struggle to accomplish: Attach copper to steel or aluminum. By using a pure copper tab to connect one power cell to another, EV manufacturers will realize a significant boost in power cell efficiency. So why do most EV manufacturers… Read more »
