Progress and Prospect of Sn-Based Metal-Organic Framework Derived Anode Materials for Metal-Ion Batteries

Abstract

In order to realize the growing demand for superior energy storage devices and electric vehicles, commercial anode candidates for next-generation rechargeable batteries need to meet the characteristics of low cost, high energy density, high capacity, and stable performance. The emerging tin-based anodes show great potential for high performance metal-ion battery anodes due to their high theoretical capacity, low cost, green harmless and high safety. Tin based anode materials include tin gold based materials, tin alloy materials, tin based oxides, tin based phosphide, tin based sulfides, multi-component composite materials, etc. However, the change in volume and structure of tin-based anode materials during the cycle has become the biggest obstacle to its development. Metal-organic frameworks (MOFs) provide a wide range of possibilities for achieving high rate capacity and excellent cycle stability by finely regulating the structure and composition of tin-based materials at the molecular level. The latest progress of tin-based materials derived from MOFs as anode materials for metal-ion batteries (including lithium ion batteries, sodium ion batteries, potassium ion batteries, magnesium ion batteries) was reviewed in this paper. Firstly, the preparation method and morphology control of tin-based MOF are briefly introduced, and the structural characteristics, storage mechanism and modification of tin-based MOF derived materials are emphatically discussed. Finally, we summarized the existing modification measures and challenges of these anode materials, and put forward the prospect of the future.
