Biomass‐Derived Carbon for High‐Performance Batteries: From Structure to Properties

“…[180][181][182] Moreover, according to the structure of BDC, some appropriate synthetic methods have been developed to prepare high-performance electrode materials, such as chemical vapor deposition, [283] hydrothermal, [119] self-assembly, [118] and simple impregnation process. [231] As a result, many batteries with high stability and high storage capacity have been developed. Figure 17 summarizes the applications of batteries in various fields, which provides a broad application prospect for environmentally friendly and low-cost BDC materials.…”

“…[227,228] Owing to the miracle of nature, many biomass materials have obvious carbon microfiber characteristics after carbonization, such as bamboo, [229] carrageenan, [230] and silk. [231] Biomass-derived carbon fibers (BDCFs) contribute to the electrode design of the battery, which can promote the application of low-cost biomass materials in energy storage devices. [232,195]…”

“…Different from the strictness of the separator, most BDTFs are easier to be designed as electrode materials due to their strong conductivities after carbonizations. [249,250] Some of them such as paper, [251] cotton, [252] and silk wadding, [231] can maintain the original state after carbonization. BDTFs with a good conductive carbon fiber network have been studied as a carbon substrate to design the structure to improve the cycle performance of the battery.…”

“…[235,238] However, owing to strong physical adsorption capacity, some biomass materials can be designed by adsorption of active mass first, and then carbonization. [231,252] A N-doped silking wadding carbon/SnO x @ reduced graphene oxide (N-SWC/SnO x @rGO) film was prepared by using the strong adsorption capacity of silking wadding to design structure. [231] A silk wadding film derived from the silkworm, which was acted as a thin film to adsorb Sn 2+ through a simple impregnation process.…”

[231] A silk wadding film derived from the silkworm, which was acted as a thin film to adsorb Sn 2+ through a simple impregnation process. Sn 2+ is well attached to the fiber surface of silking wadding owing to its physical adsorption.…”
