New sodium-ion cathode resists air damage, keeps 80% capacity after 200 cycles
SMRTR summary
Researchers at Central South University created a sodium-ion battery cathode with a radial gradient structure that resists air damage, addressing a major obstacle preventing widespread adoption of this low-cost energy storage technology. The innovative design maintains 80% capacity after 200 cycles compared to just 21% for conventional cathodes, while dramatically reducing capacity loss from air exposure.
