“…Many of the above-mentioned materials cannot be used as an anode for a lithium-ion current source due to significant volume expansion (silicon-up to 300%, germanium and transition metal oxides-up to 100-200%, graphite-no more than 10%). So, various different compositions of the above materials with graphite are promising anode materials [8].…”

The possibility of using Si-based anodes in lithium-ion batteries is actively investigated due to the increased lithium capacity of silicon. The paper reports the preparation of submicron silicon fibers on glassy carbon in the KI–KF–KCl–K2SiF6 melt at 720 °C. For this purpose, the parameters of silicon electrodeposition in the form of fibers were determined using cyclic voltammetry, and experimental samples of ordered silicon fibers with an average diameter from 0.1 to 0.3 μm were obtained under galvanostatic electrolysis conditions. Using the obtained silicon fibers, anode half-cells of a lithium-ion battery were fabricated, and its electrochemical performance under multiple lithiations and delithiations was studied. By means of voltametric studies, it is observed that charging and discharging the anode based on the obtained silicon fibers occurs at potentials from 0.2 to 0.05 V and from 0.2 to 0.5 V, respectively. A change in discharge capacity from 520 to 200 mAh g−1 during the first 50 charge/discharge cycles at a charge current of 0.1 C and a Coulombic efficiency of 98–100% was shown. The possibility of charging silicon-based anode samples at charging currents up to 2 C was also noted; the discharge capacity ranged from 25 to 250 mAh g−1.

“…One of the most effective strategies to achieve high-energydensity batteries is the development of cathode and anode materials that are cost-effective and possess high capacity. [1][2][3] Currently, silicon (Si) is considered to be one of the most promising commercial anode materials with its superior theoretical specific capacity (∼4200 mA h g −1 , graphite (G) 372 mA h g −1 ) lower deintercalation lithium potential (∼0.5 V) and extremely high reserves, the second highest in the earth's crust, as compared with the traditional carbon-based material commercial G anode. [4][5][6] However, alloy-type anode materials form a series of Li-Si alloy phases during the lithiation process, leading to a volume expansion more than three times larger than that of pure Si.…”

Silicon (Si), known for its high theoretical capacity, holds promise for developing high‐energy‐density lithium‐ion batteries (LIBs). However, the intrinsic low conductivity and substantial volume expansion limit its commercial application. Developing a binder that can suppress the massive volume expansion while improving Si conductivity is particularly important for LIBs based on Si anode. Here, grafting natural adhesive cationic guar gum (CGG) with small molecular acrylamide (AM) is proposed and applied it to the Si‐based anode. The rigid guar gum main chain and the elastic polymerized acrylamide (pAM) side chain forms a 3D network that completely encapsulated Si nanoparticles and cross‐linked with the natural hydroxyl groups on the surface of Si particles through abundant functional groups. Numerous link anchors and robust mechanical networks facilitate lithium‐ion transport and effectively mitigated the significant stress generated by silicon during charge and discharge cycles. Based on this innovative design, the Si@CGG@pAM@SP (Super P) electrode demonstrates excellent long‐term cycle stability and rate performance. The Si@CGG@pAM@SP electrode preserves 2086 mAh g−1 discharge capacity after 100 cycles (corresponding to 91.5% capacity retention). Physical characterization and electrochemical tests confirm the rationality of the polymer binder design, serving as a valuable reference for the material design of lithium‐ion batteries.
