PVAc (Polyvinyl Acetate) is a non-fluorinated, water-dispersible polymer gaining traction as a sustainable and low-cost alternative to traditional binders like PVDF. In the battery system, it is highly valued for its ability to be processed in water, eliminating the need for toxic and expensive organic solvents like NMP.
PVAc is a versatile binder that can be used in both cathodes and anodes, as well as in cutting-edge solid-state battery designs. (1) Research has shown that PVAc maintains excellent electrochemical stability even at high voltages (up to 4.5 V vs Li⁺/Li). This makes it suitable for high-energy density cathodes like LiNi₀.₅Mn₁.₅O₄ (LMNO) and LiFePO₄ (LFP). (2) In all-solid-state lithium batteries (ASSLBs), PVAc is used to create ultrathin composite electrolyte films. Its low softening temperature allows it to alleviate mechanical stress caused by the expansion of lithium during charging.
