Electrical Properties of Porous Nano Modified Lithium-ion Battery Negative Electrode Materials

Abstract

The negative electrode material of lithium-ion batteries is one of the key factors affecting the overall performance of the battery. Traditional carbon/graphite materials are prone to safety issues such as capacity loss and metal precipitation during application. Due to its high conductivity and flexibility, as well as its excellent properties in battery energy density, cycle life, and other aspects, Ti3C2 nanomaterials have brought new opportunities for the lithium-ion batteries development. The development of convenient electronic products and power equipment has put forward higher requirements for the performance of lithium-ion batteries. On the basis of introducing modification technologies for lithium-ion battery electrode materials (such as carbon coating, nanocomposition, etc.), this study further reviews and analyzes the electrochemical performance characteristics of batteries under porous nanomaterials. The purpose is to provide reference value for the selection and design synthesis of battery negative electrode materials.
