| 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 safety. This review will discuss that the comprehensive utilization of biological materials with uniform size, various morphology, 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, suggestions and outlooks on the future research directions in this field are also briefly given. |
