天津大学等国内外科研单位筛选出新型高性能电池材料

Core Insights - The article discusses the development of new high-performance battery materials by a collaborative research team from various institutions, addressing challenges faced by traditional battery materials in energy storage technology [1][2]. Group 1: New Battery Materials - A new class of two-dimensional topological disulfide monolayer materials (HfTiTe4, ZrTiTe4, and HfZrTe4) has been predicted through theoretical calculations, showing potential in fast charging performance, cycling stability, and thermal stability [1][2]. - These materials can significantly enhance the fast charging capabilities of battery anodes due to their abundant lithium and sodium ion storage sites and ultra-fast ion transport capabilities [2]. Group 2: Performance Enhancements - The new materials are expected to improve the cycling lifespan of sulfur cathodes and optimize their fast charging performance when used as sulfur cathode material carriers [2]. - The materials exhibit low resistance to ion movement, which contributes to their outstanding electrochemical performance when used in battery anodes [2]. Group 3: Stability and Thermal Resistance - The new materials possess unique chemical properties and adsorption capabilities that can effectively "capture" polysulfides, preventing them from affecting battery stability and charging efficiency [2]. - They maintain good thermal and kinetic performance across a temperature range from room temperature to approximately 227°C, making them suitable for high-temperature applications in electric vehicles, industrial energy storage systems, and high-power portable electronic devices [2].
