“…[ 1 ] With the booming evolution of hybrid electric vehicle (HEV), plug‐in hybrid electric vehicle (PHEV), and electric vehicle (EV), high‐energy‐density electrode materials are widely used. [ 2 ] As a successful case of high nickel cathode material, LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811) has been used in the commercial battery to fulfill the requirement of high energy density for LIBs. [ 3 ] However, NCM811 cathode can increase safety risks for the reason that the higher the nickel ratio, the worse the thermal stability of the positive electrode material, [ 4 ] and liquid electrolytes have been criticized for making the safety problem even worse.…”

High‐capacity cathodes and anodes in energy storage area are required for delivering high energy density due to the ever‐increasing demands in the applications of electric vehicles and power grids, which suffer from significant safety concerns and poor cycling stability at the current stage. All‐solid‐state lithium batteries (ASSLBs) have been considered to be particularly promising within the new generation of energy storage, owing to the superiority of safety, wide potential window, and long cycling life. As the key component in ASSLBs, individual solid electrolytes that can meet practical application standards are very rare due to poor performance. To the present day, numerous research efforts have been expended to find applicable solid‐state electrolytes and tremendous progress has been achieved, especially for garnet‐type solid electrolytes. Nevertheless, the garnet‐type solid electrolyte is still facing some crucial dilemmas. Hence, the issues of garnet electrolytes' ionic conductivity, the interfaces between electrodes and garnet solid electrolytes, and application of theoretical calculation on garnet electrolytes are focuses in this review. Furthermore, prospective developments and alternative approaches to the issues are presented, with an aim to improve understanding of garnet electrolytes and promote their practical applications in solid‐state batteries.

“…Researchers have done many attempts to explore the solutions to a safer Li anode. Improving the current collectors by achieving the porous (or 3D) architectures or pre‐coating layered (or conformal) decorations would smoothen the Li deposition . Blending melted Li with these porous substrates especially after lithiophilic decoration would further decrease and homogenize the local current density, mitigate the tip effect of Li adsorption during Li plating .…”

Li-metal is considered as the most promising anode material to advance the development of next-generation energy storage devices owing to its unparalleled theoretical specific capacity and extremely low redox electrochemical potential. However, safety concerns and poor cycling retention of Li-metal batteries (LMBs) caused by uncontrolled Li dendrite growth still limit their broad application. Herein, liquid polydimethylsiloxane (PDMS) terminated by -OCH 3 groups is proposed as a graftable additive to reinforce the anode dendrite suppression for LMBs. Such a grafting triggers the formation of a conformal hybrid solid electrolyte interphase (SEI) with increased fractions of LiF and Li-Si-O-based moieties, which serve as a rigid barrier and ionic conductor for uniform Li-ion flow and Li-mass deposition. The grafting protected anode endows Li/Li symmetric cells with a long lifetime over 1800 h with a much smaller voltage gap (≈25 mV) betweenLi plating and stripping, than the naked anode. The coulombic efficiency values for Li/Cu asymmetric cells in carbonate electrolyte can reach up to 97% even at a high current density of 3 mA cm −2 or high capacity up to 4 mAh cm −2 . The liquid PDMS additive shows advantage over solid siloxane additives with poor grafting ability in terms of Li surface compaction and SEI stabilization.

“…For example, Wu et al. [ 153 ] proposed a sericin conformal coating on Li metal anodes to be an efficient artificial SEI. The lithiophilic groups (i.e., OH, COOH, and CONH) could interact with Li + and homogenize ion deposition; meanwhile, the polar groups (i.e., NH 2 ) immobilized anions to inhibit the Li dendrites by reducing space charge effect.…”

Structural and compositional diversities of proteins generate a number of functions for fabricating novel and advanced materials. Recent progress in protein engineering endows flexible approaches and new functionalities, which makes the fabricated materials potentially applicable in a broad spectrum of fields. Such engineering strategies by applying proteins alone or together with other molecules derive numerous functional materials such as patterned nanometal materials/nanometallic compounds, well‐designed nanocomposites, etc. Advantages in materials’ tunability, property improvement (e.g., electronic and mechanical properties, etc.), functionalities, and biocompatibility have been demonstrated, thus providing alternatives to existing materials via conventional methods. This review summarizes and discusses the strategies of fabricating functional materials using proteins as the critical contributors. Benefiting from their versatility, proteins find their roles in engineering functional materials via acting as structure‐control agents, reaction agents, and battery components, which are emphasized in this review. The strategies of each group of functions are specifically detailed. Properties of protein‐engineered functional materials and their potential applications in the fields of microelectronics, energy storage and conversion, sensor devices, etc. are also reviewed.
