随着社会的迅速发展,能源短缺和环境恶化两大问题严重制约了全球社会文明发展以及经济发展。锂离子电池具有能量密度高、自放电率小、无记忆效应、循环性能好等诸多优点,广泛应用于各种电子设备、新能源汽车、储能系统等领域。锂离子电池的正极材料直接决定了电池的性能,研究正极材料的制备方法至关重要。综述了溶胶-凝胶法制备锂离子电池正极材料的研究进展以及溶胶-凝胶法改性正极材料的制备,并对溶胶-凝胶法制备锂离子电池正极材料未来的研究方向进行展望。
With the rapid development of society,the two major problems of energy shortage and environmental degradation have seriously restricted the development of global social civilization and economic development.Lithium-ion batteries have many advantages such as high energy density,low self-discharge rate,no memory effect,and good cycle performance,and have been widely used in various electronic devices,new energy vehicles,energy storage systems and other fields.The cathode material of lithium-ion battery directly determines the performance of the battery,and it is very important to study the preparation method of cathode material.This paper reviewed the research progress on the preparation of cathode materials for lithium-ion batteries by sol-gel method,as well as the modification method based on the preparation of sol-gel method.Finally,the future direction of preparation of cathode materials for lithium batteries by sol-gel method was discussed.
