“…The stress‐strain curves of the GPE matrixes with different CS contents are exhibited in Figure (a). It is obvious that with increasing the CS content, the mechanical properties of the GPE matrixes are visibly improved . The stress values of CSLC‐0, CSLC‐5, CSLC‐10, CSLC‐15 and CSLC‐20 are 0.75 MPa, 2.5 MPa, 2.25 MPa, 4.0 MPa and 7.0 MPa, respectively.…”

“…It is obvious that with increasing the CS content, the mechanical properties of the GPE matrixes are visibly improved. [43] The The results show that the mechanical properties of GPEs are enough for the application in LIBs, [43,44] which is attributed to the high viscosity of CS (Movie 1) as a binder that serves to reinforce the LC matrix. The serrated fluctuation of the stressstrain curves is caused by uneven and disordered network structures of the matrixes and GPEs from CS content.…”

“…Unfortunately, the mechanical properties of LC membrane as GPE matrix are poor in tensile strength, which hinders its application in LIBs.

A new gel polymer electrolyte (GPE) based on chitosan‐lignocellulose composites with a smooth and porous structure for applications in lithium‐ion batteries was prepared. The obtained GPE matrix and GPE show excellent comprehensive performances. The GPE matrix based on the composite containing 15 % chitosan (denoted CSLC‐15) had the best performance, with liquid electrolyte uptake of up to 749.1 wt %. The ionic conductivity for corresponding GPE is 2.89 mS cm−1 at room temperature, and the lithium ion transference number is 0.90. The GPE proved promising for use in lithium‐ion batteries, offering a large electrochemical window (4.8 V) and excellent interfacial compatibility (a stable impedance value of 227.97 Ω after 30 days). Moreover, the GPE shows excellent thermal and mechanical properties, and high C‐rates capability (163.13 mAh g−1, 152.53 mAh g−1, 144.27 mAh g−1, 128.45 mAh g−1, 156.12 mAh g−1, at 0.2 C, 0.5 C, 1.0 C, 2.0 C, 0.2 C, respectively) and cycle performance (161.99 mAh g−1 at the 99th cycle of 0.2 C), which proved its suitability of use in lithium‐ion batteries.

Rechargeable batteries are ubiquitous, and their usage is projected to grow tremendously over the years. They are vital to curbing the fossil fuel dependency and are destined to play a significant role in the future energy landscape. However, rising demand will eventually strain raw material resources, and potentially cripple the development and deployment of associated technologies. In this regard, alongside materials and methods involving sustainable resources, greener manufacturing and recycling potential, renewable resource derived biodegradable materials, i.e., natural biopolymers-are attracting interest for sustainable and eco-friendly future batteries. While they are being studied for nearly all aspects of a battery cell development, their exploration as an electrolyte component has been the subject of widespread investigations. These studies include, but are not limited to, their utilization as the building block for electrolyte wettable and more thermally resistant separators, as an alternative to synthetic polymers in gel polymer and solid polymer electrolytes, and as functional membranes to inhibit the loss of electroactive species in diverse battery chemistries. Here, a summary of natural biopolymer-based electrolytes and separators development that incorporate novel concepts is presented to tackle specific issues in various battery systems and future perspective underpinning their further advancement.

Electrolytes are highly important for aqueous Al ion batteries (AAIBs). However, Al metal anode usually has poor reversibility of plating/tripping, resulting in low Coulombic efficiency (CE) and poor cycling stability by using traditional Al ion electrolyte. Herein, a novel type of aqueous Al ion electrolyte with polyethylene glycol (PEG) as the primary skeleton for solvated Al ions is proposed, named as PEG‐Al@H. Outstandingly, an Al electrolyte interface (AEI) is generated on the Al metal surface during galvanostatic charging process by polymerization of PEG. It is proved that AEI, acting as the protective layer, effectively mitigates the side reaction caused by the rapid kinetic in aqueous electrolyte and prevents Al metal anode from deeply corroding. Moreover, PEG disrupts the hydrogen bond of the solvent in the electrolyte, extending the working temperature of AAIBs. The design that a full‐cell consisting of PEG‐Al@H as the electrolyte, potassium manganese hexacyanoferrate as the cathode, Al metal as anode can run over 20 000 cycles at 500 mA g−1, with an average CE higher than 95%. More importantly, even at −5 °C, for the first time, an initial capacity of 16 mAh in a pouch‐cell is achieved and maintain roughly 87% of capacity after 5500 cycles.
