Researchers Develop Technology to Extend Life of Anode-Free EV Batteries

A joint research team has been formed between researchers and institutions to address issues in anode-free electric vehicle (EV) batteries. The team proposes a new solution that utilizes ultrafine fabrication processes from semiconductor device manufacturing. This technology helps to extend the lifespan of these batteries by controlling how lithium deposits onto thin copper foil, eliminating the need for traditional anode materials like graphite.

The research focuses on overcoming a persistent issue in anode-free batteries where lithium can form sharp, spike-like structures that shorten battery life. By applying advanced fabrication techniques, the technology aims to create uniform sites for lithium deposition and promote a robust protective layer, potentially increasing battery efficiency and range.
