Berkeley Lab conductive polymer coating could enhance performance of EV batteries

Green Car Congress

Scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a conductive polymer coating—called HOS-PFM—that could enable longer lasting, more powerful lithium-ion batteries for electric vehicles. This ensures battery stability and high charge/discharge rates while enhancing battery life.

JAIST team investigates how self-repairing polymer can improve durability of silicon anodes

Green Car Congress

Although silicon anodes could greatly boost the capacity of Li-ion batteries, their performance rapidly degrades with use. With its self-healing properties, the PBS coating offers a much more stable performance in terms of capacity compared to a bare anode or one coated with PVDF, a polymer commercially used in lithium-ion batteries.

Berkeley Lab team designs active polyelectrolyte binder that allows for a doubling in capacity of conventional Li-sulfur battery

Green Car Congress

A team of researchers led by scientists at the US Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed an active polyelectrolyte binder (PEB) that actively regulates key ion transport processes within a lithium-sulfur battery, and have also shown how it functions on a molecular level.
