“…31 Alternatively, polymer-type 'pseudo' solid-state electrolytes with high ionic conductivity have also been analysed, with a significant proportion dedicated to multivalent polymer electrolytes. [32][33][34][35][36][37][38][39][40] Prolific research has been undertaken in the development of zincaqueous polymer electrolytes using cheap, flexible gelling agents; e.g., guar gum, xanthum gum, and gelatin; along with aqueous solutions of typically ZnSO 4 , but more recently, Zn(TFSI) 2 (bis(trifluoromethane)sulfonimide) or Zn(CF 3 SO 3 ) 2 . 33,34,41 The larger, bulkier anions, particularly CF 3 SO 3…”

“…A small amount of weak acetate acid (HAc) (H 2 O and HAc weight ratio of 200:1) was used as the buffering agent to suppress the hydrolysis of Zn salts and the accumulation of insulating Zn hydroxide salts on the Zn electrode surface in a more acidic environment. [25][26][27] Besides, organic tetramethylene sulfone (TMS) with SO polar groups that could form strong hydrogen bonds with H 2 O molecules was employed as the critical coordinator to further regulate the pH environment of aqueous electrolytes gently. Meanwhile, the TMS addition greatly limited the activity of H 2 O molecules and hydrogen generation by significantly strengthening the hydrogen-bonding network in aqueous electrolytes.…”

Mild aqueous Zn batteries have attracted increasing attention for energy storage due to the advantages of high safety and low cost; however, the rechargeability of Zn anodes is one major issue for practical applications. In this work, an effective approach is proposed to improve the reversibility and stability of Zn anodes using advanced acidic electrolytes. A trace amount of acetic acid (HAc) is employed as a buffering agent to provide a stable pH environment in aqueous Zn electrolytes, and thus suppress passivation from precipitation reactions on Zn electrodes. Meanwhile, tetramethylene sulfone (TMS) is introduced as the critical component to stabilize the Zn anodes in the acidic electrolyte. TMS greatly strengthens the hydrogen‐bonding network with reduced H2O activity and extends the electrochemical window of acidic electrolytes. With the optimal 3 m Zn(OTF)2 in (H2O‐HAc)/TMS acidic electrolyte (pH 1.6), the Zn electrode exhibits a coulombic efficiency of >99.8% and smooth Zn deposition. The Zn‐V2O5 full cell demonstrates ultra‐stable cycling over 20 000 cycles with a low decay rate of 0.0009% for each cycle at a negative/postive capacity ratio of 6.5. This work provides an insightful perspective to stabilize Zn electrodes by regulating the pH environment and limiting the H2O activity simultaneously for long‐life Zn anodes.

“…The development of electrolyte additives that can improve electrochemical performances over the existing electrolyte systems has become increasingly attractive recently. [59][60][61][62][63][64] The advantages of using additives are low preparation cost, easy processing, and minimum influence on the battery's interior environment. For example, in 2021, Han et al investigated the influence of adding gelatin into an aqueous electrolyte in Zn-ion batteries.…”

“…For example, in 2021, Han et al investigated the influence of adding gelatin into an aqueous electrolyte in Zn-ion batteries. [61] The authors discovered that an optimized amount of gelatin added to electrolytes could effectively improve the charge/discharge Coulombic efficiencies of batteries, thus extending the cycling stability of the batteries. When the addition of gelatin was increased from 0 to 3.5 g L −1 , a high Coulombic efficiency of Zn-ion batteries can be maintained to above 1000 cycles.…”

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.
