Abstract

Silicon-based anode materials

as the critical components of high energy density lithium ion batteries

play a significant role in using at the commercial market. This review summarizes the research progress and application of binder materials in silicon-based anode for lithium ion batteries

explains the mechanism of binder on improving electrochemical performance

and introduces the traditional silicon-based anode binder systems

such as carboxymethyl cellulose (CMC)

poly(acrylic acid) (PAA)

alginate (Alg). Polyimide (PI) material

which is widely known for its plentiful structure design

remarkable mechanical strength and reversible deformation

has been the most promising binder material to inhibit the volume expansion and avoid particle fracture of the silicon-based anode. Herein

the research progress of PI binder for silicon-based anode is systematically reviewed

the corresponding design strategies are emphatically proposed

and future novel concepts relating to research as well as application are presented.
