“…As the cathode of LIBs, the electrode material should have the requirements of high reversible capacity, high stability potential, and lower manufacturing cost [63,64]. At present, the cathode materials of LIBs are mostly LiFePO 4 , LiCoO 2 , LiMn 2 O 4 , Li 3 V 2 (PO4) 3 , and LiNi x Co y M 1-x-y O 2 , which have the characteristics of high specific capacity, non-toxicity, and low cost, but the conductivity is poor, and the mobility of lithium-ion is low [65][66][67].…”

Graphene has excellent conductivity, large specific surface area, high thermal conductivity, and sp2 hybridized carbon atomic plane. Because of these properties, graphene has shown great potential as a material for use in lithium-ion batteries (LIBs). One of its main advantages is its excellent electrical conductivity; graphene can be used as a conductive agent of electrode materials to improve the rate and cycle performance of batteries. It has a high surface area-to-volume ratio, which can increase the battery’s energy storage capacities as anode material, and it is highly flexible and can be used as a coating material on the electrodes of the battery to prevent the growth of lithium dendrites, which can cause short circuits and potentially lead to the battery catching fire or exploding. Furthermore, graphene oxide can be used as a binder material in the electrode to improve the mechanical stability and adhesion of the electrodes so as to increase the durability and lifespan of the battery. Overall, graphene has a lot of potential to improve the performance and safety of LIBs, making them a more reliable and efficient energy storage solution; the addition of graphene can greatly improve the performance of LIBs and enhance chemical stability, conductivity, capacity, and safety performance, and greatly enrich the application backgrounds of LIBs.

Lithium‐ion batteries (LIBs) are currently the predominant energy storage power source. However, the urgent issues of enhancing electrochemical performance, prolonging lifetime, preventing thermal runaway‐caused fires, and intelligent application are obstacles to their applications. Herein, bio‐inspired electrodes owning spatiotemporal management of self‐healing, fast ion transport, fire‐extinguishing, thermoresponsive switching, recycling, and flexibility are overviewed comprehensively, showing great promising potentials in practical application due to the significantly enhanced durability and thermal safety of LIBs. Taking advantage of the self‐healing core–shell structures, binders, capsules, or liquid metal alloys, these electrodes can maintain the mechanical integrity during the lithiation–delithiation cycling. After the incorporation of fire‐extinguishing binders, current collectors, or capsules, flame retardants can be released spatiotemporally during thermal runaway to ensure safety. Thermoresponsive switching electrodes are also constructed though adding thermally responsive components, which can rapidly switch LIB off under abnormal conditions and resume their functions quickly when normal operating conditions return. Finally, the challenges of bio‐inspired electrode designs are presented to optimize the spatiotemporal management of LIBs. It is anticipated that the proposed electrodes with spatiotemporal management will not only promote industrial application, but also strengthen the fundamental research of bionics in energy storage.
