Four kinds of polymer particles were synthesized and used as adhesives in the separators of lithium batteries. The polymer particle adhesives G3 and G4 are spherical particles with uniform size when the mass ratio of ethanol to water is 85:15.
Polymer binders used in Li-ion batteries, although not electrochemically active, are essential components in the electrodes, along with acetylene black (AB) conductive additives and the active materials (AM) that store lithium ions. The bulk polymer differentiates into three physical states when in contact with a particle surface.
Furthermore, it explores the problems identified in traditional polymer binders and examines the research trends in next-generation polymer binder materials for lithium-ion batteries as alternatives. To date, the widespread use of N-methyl-2-pyrrolidone (NMP) as a solvent in lithium battery electrode production has been a standard practice.
The electrochemical performance of lithium batteries is good. However, the synthesis process of the polymer particle adhesive is complicated and its price is high. Therefore, it is particularly important to develop a kind of polymer particle adhesive that can be used for lithium battery separators.
