Electrochemical measurements conducted in Si/Gr||Li metal and NMC622||Si/Gr full cells led to the selection of a chitosan binder with a high DP of 1618 and a DA of 50% (DA50) as the optimized version for evaluating Si/Gr anodes in battery cells .
It is also possible to use metallic lithium as a negative electrode to achieve high energy and power density. Assembled with solid-state electrolyte, all-solid-state batteries offer a potential solution to the safety problem and increase the energy density of lithium-ion batteries.
The solid-state sintering method involves incorporating a precise amount of lithium supplement into the cathode material of S-LIBs, followed by high-temperature annealing to replenish lithium, repair material defects, and restore the material structure (Wu et al., 2023).
In commercialized LIBs, Li insertion materials that can reversibly insert and extract Li-ions coupled with electron exchange while maintaining the framework structure of the materials are used as both positive and negative electrodes.
This review focuses on the crucial role of binders in battery electrode assembly and emphasizes the increasingly reduced use of toxic chemicals, such as NMP and DMC, which are commonly used in the preparation of non-aqueous binders, such as PVDF and PAN.
The conductive carbon that remains can provide a protective coating to the bulk material during the grinding process (Meng et al., 2019), while the LiF produced from the thermal decomposition of PVDF during sintering can enhance material performance (Fan et al., 2021).
