A durable electrochemical performance in lithium-ion batteries (LIBs) is increasingly important in future applications. Various strategies were used to develop functional binders for long cycles, high loading, and fast charging. However, despite constant efforts, the strategies mentioned above remain critically challenging and must be addressed. Herein, we utilized a nontoxic, water-soluble, and bioderived polymethylene-based binder containing a high concentration of carboxylic acid functional groups as side chains, demonstrating improved lithium-ion transport and minimizing electrolyte decomposition. Polymethylene’s less flexible rod-like polymer architecture succeeds in exhibiting long cycling at 1 C with a specific capacity of 325 mAh g–1 and capacity retention of 79% at the 710th cycle. It also performed better fast charging behavior at 5 C with a specific capacity of 54 mAh g–1 and showed better rate and long cycling stability with high loading of graphite up to 3.4 mg cm–2. Hence, a poly(fumaric acid) binder enhances the LIB’s electrochemical performance and mechanical strength.

“…[11,12] Although hard carbon has a good application prospect in Nib, its cycling performance and rate ability need to be improved, and hard carbon tends to form a prominent solid electrolyte interface layer (SEI) on a large surface area, resulting in a low initial cycling e ciency (ICE) of Nib. [13][14][15][16][17][18][19] As a kind of carbon material with wide source, high yield and simple preparation, carbon black (CB) can be prepared by thermal cracking method, that is, by cracking acetylene at high temperature. CB is mostly composed of black powder of elemental carbon (EC), which is widely used in life, such as used as a reinforcing agent for automobile tires and rubber automobiles.…”

Currently, the anode of sodium-ion battery is mainly made of carbon material, and the carbon black made of acetylene has the advantages of low cost, high purity and simple process, etc. The particle size of carbon black has a great influence on the storage capacity of sodium ions, in this study, carbon black particles with different particle sizes were prepared by chemical vapour deposition method by changing the temperature and gas flow rate, and the effects of the temperature and the gas flow rate on the size of the carbon black were investigated, and the effect of the particle size of carbon black on the performance of the battery was studied. The effect of temperature and gas flow rate on the particle size of carbon black was investigated, and then the effect of the particle size of carbon black on the battery performance was studied. The larger the gas flow rate of acetylene, the smaller the particle size of carbon black generated. The carbon black CB-3 generated by holding at 900 ℃ and an acetylene flow rate of 300 mL/min for 30 min kept the capacity of 112.36 mAh/g after 180 cycles, and the specific capacity of the first discharge was 414.66 mAh/g, and the reversible specific capacity at 2 A/g still had 92.12 mA/g. This work helps to provide new ideas for research in enhancing the electrochemical performance of sodium-ion battery materials.

The binder's choice holds immense significance in the quest for robust electrochemical performances of lithium/sodium‐ion battery's (LIB/SIB) electrodes. Conventional PVDF binder is a passive polymer lacking the ability to transport Li+/Na+ and facilitate ion kinetics. This limitation poses constraints in achieving high specific capacity, fast charging, and long cycle life. Herein, a novel water‐soluble concentrated imidazolium functionalized poly(ionic liquid), poly(oxycarbonylmethylene 1‐allyl‐3‐methyimidazolium) (PMAI) is synthesized, and evaluated it as binder in LIB/SIB. PMAI‐based anodic‐half cell exhibits excellent electrochemical performance, achieving higher capacities (297 mAhg−1 at 1C for LIBs and 250 mAhg−1 at 60 mAg−1 for SIBs) and good cycle stability (80 % capacity retention after 750 cycles for LIBs; 96% capacity retention after 200 cycles for SIBs), compared to PVDF binder. In addition, PMAI/Gr delivers a higher discharge capacity of 85 mAhg−1 than PVDF/Gr with 47 mAhg−1 at 5C. PMAI‐containing electrodes show better rate capability at different current densities than PVDF binder in LIB/SIB. The enhanced ion diffusion coefficient, lower resistance and decreased activation energy of desolvation, are ascribed to densely polar ionic liquid groups along the polymer and formation of a functionalized SEI via binder reduction. The novel PMAI binder's design and full‐cell examination confirm its potential in secondary‐ion battery applications.
