In situ heterogeneous interface construction boosting fast ion/electron transfer for high-performances lithium/potassium storage

Molybdenum diselenide (MoSe2) materials have aroused great attention for Li/K storage due to its high theoretical capacity and low cost. However, MoSe2 often suffer from poor rate performances and unsatisfied cyclability for Li/K storage due to sluggish kinetics and the structure collapse upon cycling. Herein, a MoSe2-SnS heterostructure, SnS nanoparticles anchored at MoSe2-graphene matrix ([email protected]2-GR), was constructed to improve rate...
