摘要

Pursuing for novel electrode materials is significant for the progress of sodium ion batteries (SIBs). Here, a multilayered electride prepared by simple thermal decomposition of solid Ca₃N₂, namely Ca₂N, is introduced as a new anode material of SIBs for the first time, and a compression molding electrode fabricated by pressing Ca₂N powder into nickel foam is applied to protect Ca₂N from trace moisture and oxygen. The as-prepared electrode delivers an initial discharge capacity of 1110.5 mAh g^-1 and a reversible discharge capacity of ∼320 mAh g^-1. These results suggest that Ca₂N has a great potential for sodium ion batteries.
