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.

Researchers develop shape-memorized current collector to brake battery thermal runaway

Green Car Congress

Unlike traditional current collectors made of commercial copper foils, SMCC is made of a micropatterned shape memory micron-sized film with copper deposition. F, a microscopic, 3D pattern programmed into the polymer appeared, breaking apart the copper layer and stopping the flow of electrons. At around 197 ?F, 2c03645.
