Abstract:Silicon-based anode has a high theoretical specific capacity (4200 mAh g-1), which can alternative graphite electrode and become a new generation of high-capacity lithium-ion batteries anode. However, the huge volume expansion caused by the Si anode in the battery cycle will lead to the crushing of Si particles, electrical contact failure and other side reactions, and eventually lead to the rapid decay of battery capacity and the deterioration of the cycle stability. Binders are an important component of the negative electrode of lithium-ion batteries and, although in small amounts, play a key role in stabilizing the electrode cycle. In this paper, the solvent types and polymerization structures (including linear, cross-linked and conjugated conductive polymers) of Si-based negative battery adhesives are classified, and the adhesion mechanism, advantages, limitations and properties are described. Finally, the direction and development prospects of further research are prospected.
