Recent Advances in Anode Materials for Sodium-Ion Batteries

Although lithium-ion battery (LIB) technology has prevailed for years, the growing pressure and increased cost of lithium sources urge rapid development other promising energy storage devices. As a low-cost alternative, sodium-ion batteries (SIBs) with similar properties electrochemical reaction have caught researchers’ attention. Nevertheless, great challenges inferior reversible capacity poor lifespan induced by bigger ionic radius sodium ions still exist. To solve these problems, improvements to anode materials prove be an effective way. Herein, latest research on anodes in SIBs is summarized, further prospects are also illustrated.
