I'm always keen to read about innovative new energy storage technologies and projects. I've had a particular interest in sodium-ion batteries since Hyperion partnered with Faradion, a UK based sodium-ion battery manufacturer to recruit their Head of Cell Manufacturing last year. Sodium-ion batteries have huge potential as a rival to Lithium-ion as their materials are much more abundant leading to much lower costs. This could be realised when they are manufactured at scale. I'll be keeping an eye on this project as hopefully it can lead to many more similar projects proving sodium-ion can compete with lithium. Watch this space.
