A general strategy for the <i>in situ</i> construction of CoSe ₂ –MSe _<i>x</i> @GA (M = Zn, Ni, and Fe) heterostructures for effective sodium storage

Abstract

A facile and general strategy is developed for constructing graphene aerogels with in situ encapsulated bimetallic selenide heterostructure materials exhibiting high rate-capabilities and long cycling stabilities in sodium-ion batteries.
