New anode technologies for electric vehicle batteries

Anodes constitute around 20-30% of EV battery mass and have a much higher energy density than cathodes. Yet, negative electrodes have received far less attention than positive ones. For many years, anode technology based on graphite seemed to stagnate, while in fact, there are some exciting developments which are expected to improve battery performance and reduce the dependency of the EU and the US on China’s supply chain.

Silicon, lithium metal and anode-free technologies promise higher energy density, improved sustainability, and lower costs, although they still struggle with volume expansion and low lifetime.

COBRA's new Market Intelligence Report looks deeper into opportunities and challenges related to new anode technologies, based on the most recent research and commercial developments. It also explores the dynamics of the anode market, explaining the economy of anode active materials, strategic interests of the EU in the graphite supply chain, as well as key global anode producers and innovators. In addition, this edition’s contributor ReSiTec gives insights into the production of silicon anodes and how to make them more sustainable by using recycled material from PV panels manufacturing.
