Newly developed composite may enable high effective energy storage

Sodium-ion batteries are an exciting alternative for post-lithium energy storage, while their anode materials of high performance are still limited. Phosphorus-based materials enable high-capacity anodes for sodium-ion batteries, but often face poor performance retentions owing to low conductivity and large volume expansion. To produce a cost-effective sodium-ion battery, researchers based at the Beijing University of Technology, have synthesized a series of P-/Sn-based composites that serves as high-capacity and high-stability anode materials, enabling a full battery that retains a capacity retention of 97.7% after 50 cycles.
