“…Optimizing the composition of electrolytes with natural abundant and nontoxic materials to replace the toxic materials in traditional electrolytes has become one of the hot topics in this research area. [46] Therefore, using nontoxic proteins as major components to directly prepare electrolytes for rechargeable batteries has been intensively reported in different battery systems recently (Table 1). [47][48][49][50][51][52][53][54] Moreover, as a representative of biological macromolecules, the unique self-assembly properties of proteins at the molecular level show immense potential for designing aqueous electrolytes.…”

In pursuit of reducing environmental impact during battery manufacture, the utilization of nontoxic and renewable materials is essential for building a sustainable future. As one of the most intensively investigated biomaterials, proteins have recently been applied in various high‐performance rechargeable batteries. In this review, the opportunities and challenges of using protein‐based materials for high‐performance energy storage devices are discussed. Recent developments of directly using proteins as active components (e.g., electrolytes, separators, catalysts or binders) in rechargeable batteries are summarized. The advantages and disadvantages of using proteins are compared with the traditional counterparts, and the working mechanisms when using proteins to improve the electrochemical performances of rechargeable batteries are elucidated. Finally, the future development of applying biomaterials to build better batteries is predicted.

“…The growth of lithium dendrite is a main problem affecting the safety performance of LIBs. It leads to irreversible capacity decay, low CE, and potential safety problems of LIBs. , It is generally agreed that overcharging and fast charging can result in uneven lithium-ion deposition and uneven charge distributions on the anode surface. These active substances interact to form dendrite on the anode electrodes in the presence of liquid electrolyte, resulting in breakdown of separator and battery short circuit …”

In the past decade, the synthesis and application of hollow multishell micro/nanostructures have experienced substantial developments. Hollow micro-and nanostructures demonstrate a promising future in energy storage. However, hollow micro/nanostructures as anode electrodes for lithium-ion batteries (LIBs) have not been systematically summarized. In this paper, the challenges faced by lithium anode materials are reviewed. Then, the application of hollow micro/nanostructures as lithium anode electrodes is reviewed in terms of the charging and discharging mechanisms of multishell hollow anode electrodes. Eventually, the prospects for the development of multishell hollow micro/nanostructures as lithium anode electrodes are further discussed.

“…Meanwhile, the good wettability of carbon nanotube to liquid organic electrolyte ensures sufficient triple-phase boundary for electrochemical reactions and fast transportation of lithium ions and electrons. [7][8] Furthermore, ethers such as dimethyl ether (DME) and tetraethyleneglycol dimethyl ether (TEGDME) have been commonly employed as the liquid organic electrolytes of lithium-oxygen batteries for their wide electrochemical window (> 4.0 V), good solubility to O 2 as well as low volatility. [9] Besides, the low polarity of ethers could contribute to a better dissolution of Li 2 O 2 to relieve the block on cathode in the discharging process.…”

Lithium‐oxygen batteries have received great research interest owing to their ultrahigh theoretical energy density and are considered as one of the promising secondary batteries. However, there are still some challenges in their practical application, like liquid organic electrolyte evaporation in the semi‐open system and instability in the high‐voltage oxidizing environment. In this work, a cellulose acetate‐based gel polymer electrolyte (CA@GPE) is proposed, whose cross‐linked microporous structure ensures the ultrahigh liquid electrolyte uptake of 2391%. The prepared CA@GPE exhibits a high lithium‐ion transference number of 0.595, a satisfying ionic conductivity of 0.47 mS cm−1 and a wide electrochemical stability window up to 5.0 V. The Li//Li symmetric cell employing CA@GPE could cycle stably over 1200 h. The lithium‐oxygen battery with CA@GPE presents a superb cycling lifetime of 370 cycles at 0.1 mA cm−2 under 0.25 mAh cm−2. This work offers a possible strategy to realize long‐cycling stability lithium‐oxygen batteries.
