Hard carbon is regarded as a promising anode material for sodium-ion batteries (SIBs). However, it usually suffers from the issues of low initial Coulombic efficiency (ICE) and poor rate performance, severely hindering its practical application. Herein, flexible, self-supporting, scalable hard paper (HCP) derived renewable tissue rationally designed prepared additive-free room/low-temperature SIBs with high ICE. In ether electrolyte, such HCP achieves an ICE up to 91.2% superior high-rate...
Abstract Thanks to low costs and the abundance of resources, sodium‐ion (SIBs) potassium‐ion batteries (PIBs) have emerged as leading candidates for next‐generation energy storage devices. So far, only few materials can serve host both Na + K ions.
