Abstract

provides unprecedented opportunities for altering and tuning material properties. Surface-amorphized TiO@graphene synthesized using a designed low temperature-phase transformation technique exhibits significantly improved rate capability compared to well-crystallized TiO@graphene and bare TiO electrodes. These improvements facilitates lithium-ion transport in both insertion and extraction processes and enhance electrolyte absorption capability.

摘要

为改变和调节材料性能提供了前所未有的机会。使用设计的低温相变技术合成的表面非晶化TiO@石墨烯与结晶良好的TiO@石墨烯和裸TiO电极相比,其倍率性能有显著提高。这些改进促进了锂离子在嵌入和脱嵌过程中的传输,并增强了电解质吸收能力。
