Future development of positive electrode materials for sodium batteries
Positive Electrode Materials for Li-Ion and Li-Batteries
Positive electrodes for Li-ion and lithium batteries (also termed "cathodes") have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade. Early on, carbonaceous materials dominated the negative electrode and hence most of the possible improvements in the cell were …
Discovery brings all-solid-state sodium batteries closer to …
The pursuit of greener energy also requires efficient rechargeable batteries to store that energy. While lithium-ion batteries are currently the most widely used, all-solid-state sodium batteries are attracting attention as sodium is far more plentiful than lithium. This should make sodium batteries less expensive, and solid-state …

Sodium-ion battery
Similar ionic radii of lithium and iron result in their mixing in the cathode material during battery cycling, and a resultant loss of cyclable charge. A downside of the larger ionic radius of Na + is a slower intercalation kinetics of sodium-ion electrode materials. [4] The development of Na+ batteries started in the 1990s.
