国内外科研单位联合筛选出新型高性能电池材料

Core Viewpoint - The rapid development of energy storage technology has led to the identification of new high-performance battery materials, which address challenges faced by traditional battery materials in energy storage capacity, charging speed, and cycle longevity [1][2]. Group 1: New Battery Materials - A collaborative research team from various institutions, including Tianjin University and Shanghai Jiao Tong University, has predicted a new class of two-dimensional topological disulfide monolayer materials (HfTiTe4, ZrTiTe4, and HfZrTe4) through theoretical calculations [1]. - These new materials exhibit potential in fast charging performance, cycle stability, and thermal stability, making them suitable for applications in portable electronic devices, electric vehicles, and large-scale energy storage systems [1][2]. Group 2: Performance Enhancements - As anode active materials, these new materials provide abundant lithium and sodium ion storage sites and ultra-fast ion transport capabilities, significantly enhancing the fast charging performance of batteries [2]. - When used as a sulfur cathode material carrier, these materials are expected to greatly extend the cycle life of the cathode and optimize its fast charging performance [2]. Group 3: Stability and Efficiency - The new two-dimensional materials possess unique chemical properties and adsorption capabilities that can effectively "capture" polysulfides, preventing them from affecting battery stability and charging efficiency [2]. - The materials maintain good thermal and kinetic performance across a temperature range from room temperature to approximately 227°C, supporting applications in high-temperature scenarios such as outdoor driving of new energy vehicles and industrial energy storage systems [2].
