“…Also, SPE–40 wt% LiTFSI showed slightly better electrochemical stability than SPE–35 wt% LiTFSI and SPE–45 wt% LiTFSI due to its high ion conduction 17 . However, that of SPE–35 wt% LiTFSI was almost the same as that of SPE–45 wt% LiTFSI.…”

“…Finally, a digital multimeter (Keithley 2000) was used for a short circuit test before connecting the coin cell to the channel's battery tester. Linear sweep voltammetry (LSV), CV, open‐circuit voltage (OCV) and GCD were done on SSLIBs with the optimum electrolytes of our recent work 17 (SPE‐35, SPE‐40 and SPE–45 wt% LiTFSI) using a potentiostat by Schlumberger Instrument Princeton Applied Research (VersaSTAT 4, Berwyn, PA, USA) and a battery testing system (CT‐3008 W‐5V10mA‐S1, NEWARE). The CV, OCV and GCD were all carried out at 100 °C owing to the favorable response for certain electrochemical tests at this temperature.…”

In situ UV‐initiated polymerization was performed to prepare solid polymer electrolytes (SPEs) based on epoxidized natural rubber‐graft‐acrylonitrile (ENR‐g‐ACN) by employing lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) as a doping salt. A solid‐state lithium‐ion battery (SSLIB) was fabricated using ENR‐g‐ACN‐LiTFSI as an electrolyte and lithium metal and graphite as electrodes. The SSLIB's performance was evaluated to investigate the electrochemical stability window (ESW), redox behavior, voltage stabilization measurement and electrochemical capacitance response. The ESW of the SPE reached a reasonable value of 5.6 V (vs Li/Li+). The absence of redox peaks on the cyclic voltammetry (CV) curve indicates that the cell behaved more like a capacitor than a battery. At an open‐circuit voltage of 2.78 V, the battery's performance also showed a low capacity due to parasitic (unwanted) reactions, electrolyte degradation or the battery's age. The performance of an electrical double‐layer capacitor (EDLC) was also analyzed by linear sweep voltammetry, CV and galvanostatic charge–discharge. The ESW of the SPE was obtained as 2.7 V. The specific capacitance of the EDLC was found to be 6 F g−1 at 0.005 mA cm−2 and 60 °C. The fabrication of affordable and secure SSLIBs and EDLCs with the use of rubber materials will be successful if this strategy is developed. © 2023 Society of Industrial Chemistry.

“…NR, the most widely used general-purpose rubber, exhibits the advantages of high tensile strength and good wear resistance. However, NR is nonpolar, so it was modified through epoxidation. − As depicted in Scheme a, NR’s molecular chains were introduced into the polar epoxy functional groups after epoxy functionalization, thus providing active sites for the subsequent reaction of NR. , In addition, glycinamide hydrochloride (GA) was adopted to modify PAA, and a primary amine group was introduced into the side chain of PAA. The resulting product was termed PAG.…”

Silicon (Si), a high-capacity lithium-ion battery anode material, has aroused wide attention. Its further practical application has been limited by its huge volume change during the cycle. To reduce this defect, the double cross-linked product of glycinamide hydrochloride modified poly(acrylic acid) (PAG) and epoxidized natural rubber (ENR) was developed as a water-based binder to obtain sufficient elasticity and a sufficiently strong adhesive force. Due to the double crosslinked structures in the system, the binder was enabled to effectively disperse and transfer the stress generated by the volume expansion of the Si particles and keep the integrity of the electrode during the cycle, thus obtaining excellent cycle performance. When the current density was 1 A g −1 , PE55 (PAG: ENR = 1:1 cross-linked polymer) electrode still achieved a specific capacity of 2322.2 mAh g −1 after 100 cycles of constant current charge and discharge, and PE55 binder exhibited excellent bonding properties (4.45 N) and mechanical properties (stress: 5.51 MPa, strain: 87.4%). The comparison of poly(acrylic acid) (PAA) electrodes suggests that the introduction of elastic polymer and the construction of double cross-linked structures can increase the stability of Si anodes.

Amid the search for alternatives to petrochemical‐based polymers and growing concern for environmental sustainability, natural polymers have gained significant attention. These polymers have potential applications in household appliances to advanced energy systems and offer a way to address the depletion and sustainability challenges associated with synthetic polymers. One such natural source of polymer is natural rubber (NR), which has been developed as a highly performing material in electrodes and electrolytes. Nowadays, researchers are more interested in NR due to its sustainability, affordability, elastomeric properties, and low glass transition temperature. This article presents a comprehensive exploration of NR characteristics, delving into its elasticity, glass transition temperature, and an extensive evaluation of its potential as a hydrogel electrolyte. Furthermore, this investigation showcases NR's capability to mitigate potential long‐term consequences of synthetic materials. Given NR's inherent insulating nature, a meticulous analysis of the interplay between NR composites and their electrical properties within electrodes is prompted. This article provides a review of past research, growth and development, and prospects of NR and its derivatives as in applications including electrochemical energy storage, energy harvesting, wastewater treatment, and slow‐release fertilizers. Moreover, the study briefly underscores the importance of NR while acknowledging its limitations.
