Materials in nature have evolved to the most efficient forms and have adapted to various environmental conditions over tens of thousands of years. Because of their versatile functionalities and environmental friendliness, numerous attempts have been made to use bio‐inspired materials for industrial applications, establishing the importance of biomimetics. Biomimetics have become pivotal to the search for technological breakthroughs in the area of rechargeable secondary batteries. Here, the characteristics of bio‐inspired materials that are useful for secondary batteries as well as their benefits for application as the main components of batteries (e.g., electrodes, separators, and binders) are discussed. The use of bio‐inspired materials for the synthesis of nanomaterials with complex structures, low‐cost electrode materials prepared from biomass, and biomolecular organic electrodes for lithium‐ion batteries are also introduced. In addition, nature‐derived separators and binders are discussed, including their effects on enhancing battery performance and safety. Recent developments toward next‐generation secondary batteries including sodium‐ion batteries, zinc‐ion batteries, and flexible batteries are also mentioned to understand the feasibility of using bio‐inspired materials in these new battery systems. Finally, current research trends are covered and future directions are proposed to provide important insights into scientific and practical issues in the development of biomimetics technologies for secondary batteries.

“…Thus, alternative cathode materials are ought to be explored. a-LiFeO 2 , with a disordered rock-salt structure, has been considered as a potential candidate to replace LiCoO 2 due to its high theoretical capacity (282 mAh g -1 ), high elemental abundance, the low cost of the raw materials, environmental friendliness and safety during operation [4][5][6][7][8][9]. Unfortunately, a-LiFeO 2 suffers from an intrinsically poor electronic conductivity and slow lithium-ion diffusion kinetics.…”

Abstractα-LiFeO2 is a promising cathode material for lithium-ion batteries due to its theoretically high specific capacity (282 mAh g−1), abundant nature, low cost of raw materials and environmental friendliness. However, the intrinsic sluggish kinetics and poor electronic conductivity of α-LiFeO2 prevent its practical use. In this work, we introduce a novel electrostatic layer-by-layer self-assembly method using PAH and PSS charged polyelectrolytes to grow in situ Ag nanoparticles on the surface of α-LiFeO2 nanorods to improve the electronic and ionic conductivity in this material. The experimental results show that such tailored design effectively improves the cycling stability and provides the material with a superior rate capability. The Ag-1D α-LiFeO2 material delivers a high discharge capacity of 162.6 mAh g−1 at 0.5 C and a capacity retention of 89.6% after 50 cycles. The excellent electrochemical behavior may be ascribed to synergistic effects which combine the use of Ag NPs, which provide with improved electronic conductivities, and the large specific surface areas given by the 1D morphology of the nanorods, providing increased lithium and electron conduction pathways.

A series of silicon-doped lithium manganese oxides were obtained via a sol-gel process. XRD characterization results indicate that the silicon-doped samples retain the spinel structure of LiMn2O4. Electrochemical tests show that introducing silicon ions into the spinel structure can have a great effect on reversible capacity and cycling stability. When cycled at 0.5 C, the optimal Si-doped LiMn2O4 can exhibit a pretty high initial capacity of 140.8 mAh g−1 with excellent retention of 91.1% after 100 cycles, which is higher than that of the LiMn2O4, LiMn1.975Si0.025O4, and LiMn1.925Si0.075O4 samples. Moreover, the optimal Si-doped LiMn2O4 can exhibit 88.3 mAh g−1 with satisfactory cycling performance at 10 C. These satisfactory results are mainly contributed by the more regular and increased MnO6 octahedra and even size distribution in the silicon-doped samples obtained by sol-gel technology.
