“…Such parameters contributed to the improved performance resulting from the trapping of polysulfides by the micro fibrillated cellulose, along with the inhibition of Li x S precipitation during discharge. In another work, lignocellulose fibers of 50-300 µm, obtained after wood treatment, were used to fabricate GPEs using a solution casting method followed by soaking the membrane into 1 m LiTFSI in 1,2 dioxolane/dimethoxymethane (1:1 by volume) with 1 wt% LiNO 3 for 2 h. [116] The GPE's porous structure with a large number of cavities translated to an ionic conductivity of 6.52 mS cm −1 and an electrochemical stability window of 5.3 V. Hydroxyl groups on lignocelluloses form hydrogen bonds with anions in lithium salts and the strongly electronegative polysulfides, resulting in a high Li + transference number of 0.79 and suppressing the shuttle effect by immobilizing polysulfides on the cathode side of the GPE. Consequently, a capacity of 653 mAh g −1 at 20 mA g −1 after 100 cycles was achieved in a Li-S cell.…”

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.

“…In order to know the liquid absorption rates of GPEs, the films were soaked in the electrolyte overnight and the liquid absorption rates of GPEs were calculated by ref. Where d, S and R b are the thickness, the effective contact area, and the bulk resistance of the GPE, respectively [3] . The Li-Li symmetrical cells with GPEs (Li/GPEs/Li) were tested on NEWARE (BTS CT3008 5 V/10 mA) instrument with a constant current density of 0.5 mA cm −2 and a discharge capacity of 0.5 mAh cm −2 in a timelimited charge-discharge mode.…”

“…Although lithium-ion battery is one of the most popular batteries in secondary batteries in recent years, it is temporarily unable to fulfill the demands of future electric vehicle power batteries due to its low energy density (150-300 Wh g −1 ) [1][2][3] . Under this circumstance, Li-S battery is gradually receiving attentions from the general public because of its high theoretical energy density (2600 Wh kg −1 ) [4 , 5] .…”

Lithium-sulfur (Li-S) battery can satisfy the need of the future power battery market because of its high energy density, but the hidden dangers caused by lithium anode have seriously hindered their commercialization. Herein, an innovative gel polymer electrolyte (GPE) composed of polyvinylidene fluoride (PVDF) and organo-polysulfide polymer (PSPEG) is proposed, which could be used in semisolid-state Li-S batteries for protection of Li anodes. Particularly, organo-polysulfide polymer could chemically/electrochemically generate both inorganic and organic components simultaneously in-situ once contacting fresh Li metal surface and/or during discharging processes. And these inorganic/organic components could participate in the formation of the SEI layer and finally constitute a stable and flexible hybrid SEI layer on the surface of Li metal anode. Moreover, the organic components were permselective to lithium ions against anions. Therefore, PVDF/PSPEG GPE ensures the ideal chemical and electrochemical properties for Li-S batteries. Our work demonstrates an effective solution to solve the problems about Li anodes and contributes to the development of the safe Li metal batteries.

“…[14] For example, Song et al prepared a gel polymer electrolyte based on selected lignocellulose (LC) for LiÀ S batteries. [15] The assembled LiÀ S battery retained 55.1 % of the initial capacity for 100 cycles at 20 mA/g. Lignocellulose (LC) is the most important renewable carbon resource, which is composed of hemicellulose, cellulose and lignin.…”

An environmentally friendly gel polymer electrolyte (GPE) applied in lithium-sulfur (LiÀ S) batteries is based on the modified lignocellulose (LC), which is made from raw LC material with NaOH/urea aqueous solution through a simple partial dissolution method. Surfaces of fibers dissolve during the dissolution process and form a matrix among the fibers during the regeneration stage, which significantly improves the mechanical properties by up to five times. Meanwhile, the GPE (G3) shows enough liquid electrolyte absorption (144 %) and good thermal stability when the dissolution time is 20 min. It has high lithium ion transference number of 0.74 and good ion conductivity of 2.42 mS cm À 1 , which is an order higher than that of the commercial separator. Besides, sufficient electrochemical stability and interface compatibility can meet requirements of LiÀ S batteries. Compared with the battery with the commercial separator, Li/G3/S battery exhibits enhanced rate and cycling performance, which shows that G3 can effectively suppress the "shuttle effect".
