摘　　要：锂离子电池是一类极具潜力的新型二次化学储能器件,被广泛应用于便携式电子设备、电动交通工具和智能电网等领域。高性能电极材料的设计和合成是获得高能量密度、长循环寿命、高安全性锂离子电池的关键。文章针对锂离子电池电极材料存在制备工艺复杂、结构难以控制、活性物质利用率低、循环稳定性和倍率性能差等问题,从生物资源高效利用角度出发,结合生物材料尺寸均匀、形态多变、结构精密、环境友好等优点,综述了生物模板法合成锂离子电池电极材料的研究进展,并对该领域的发展方向进行了展望。Lithium-ion batteries are considered as the high-potential secondary energy storage devices, which have been widely applied in many fields, such as portable electronic devices, electric vehicles and large-scale electricity storage in smart or intelligent grids. However, the design and synthesis of high-performance electrode materials are the crucial steps toward the realization of lithium-ion batteries with high energy density, long cycle life and high safe- ty. This review discusses that the comprehensive utilization of biological materials with uniform size, various morpho- logy, elaborate architecture, environmental benignity can overcome several fundamental issues of electrode materials, such as complex preparation, uncontrolled structure, low utilization of active materials, poor cycling stability and rate capability. Meanwhile, it also gives brief suggestions and outlooks on the future research directions in this field.
