Leaving Water in Sodium-Ion Batteries Nearly Doubles Their Energy Storage
University of Surrey researchers have discovered that keeping water in sodium-ion battery cathodes nearly doubles their energy storage capacity. The counterintuitive finding upends conventional wisdom that water must be removed from battery materials during manufacturing.
Key Takeaways
- Keeping water in sodium-ion battery cathodes nearly doubles energy storage capacity
- Water expands cathode layers, giving sodium ions more room to move during charging
