Abstract:

The energy density of lithium-ion batteries with graphite anodes is nearing its theoretical limit but still falls short of the demand for higher-energy-density batteries. Lithium-ion batteries with silicon-based anodes, lithium-sulfur batteries, and lithium-metal batteries, which offer higher specific capacities, can achieve a leap in energy density. However, these batteries face critical challenges in cycle stability and safety that must be urgently addressed. The use of electrode materials with high specific capacities inevitably leads to greater volume changes, posing significant challenges to battery preparation and stable operation. Scaffold materials offer excellent tunability, mechanical strength, and porosity, making them a promising solution for mitigating volume effects in high-specific-capacity electrode materials. This review classifies scaffold materials, analyzes the challenges faced by different components in high-specific-capacity batteries, and examines their applications in the cathode, separator, electrolyte, and anode of lithium-ion batteries. It discusses the working principles, advantages, and disadvantages of scaffold materials for different battery components. It also identifies key issues and severe challenges to advancing scaffold materials in the field of lithium batteries. Ultimately, it highlights potential future research directions for scaffold materials. This review aims to provide valuable insights and reference outputs for promoting the continuous advancement of battery technology through scaffold materials.
