Exploring the Capability of Framework Materials to Improve Cathodes’ Performance for High-energy Lithium-ion Batteries

Abstract

Lithiated transition metal oxides are the most important cathode materials for lithium-ion batteries. Many efforts have been devoted in recent years to improving their energy density, stability, and safety, as demonstrated by thousands of publications. However, the commercialization of several promising materials is limited due to obstacles like stability limitations. To overcome the limitations of energetically high-voltage or high-capacity cathode materials, unconventional solutions for their surface engineering were suggested; among them, metal–organic frameworks (MOFs) and zeolites have been employed. MOFs possess favorable characteristics for stabilization goals, including manageable structures, topological control, high porosity, large surface area, and low density. This review article explores promising strategies for improving the electrochemical behavior of favorable cathode materials through surface modifications by using MOFs and zeolites. Investigating the potential of this frameworks-based surface engineering for high energy density batteries’ electrodes is essential for optimal control of their surface chemistry. It may be highly effective to upgrade the performance of high-energy cathode materials, thus extending the practical use of very high energy density rechargeable batteries.
