## Abstract

It is an assignment to be solved to provide an electrode for secondary battery, electrode in which the active material is suppressed from coming off or falling down from the electricity collector, and that has excellent cyclic performance. It is characterized in that, in an electrode for secondary battery, the electrode being manufactured via an application step of applying a binder resin and an active material onto a surface of electricity collector, said binder resin is an alkoxysilyl group-containing resin that has a structure being specified by formula (I): wherein “R1” is an alkyl group whose number of carbon atoms is from 1 to 8; “R2” is an alkyl group or alkoxyl group whose number of carbon atoms is from 1 to 8; and “q” is an integer of from 1 to 100.

## Claims

### Claim 1

A manufacturing process for electrode for secondary battery, the manufacturing process comprising:
an application step of applying a binder resin and an active material onto a surface of electricity collector; and
a curing step of curing said binder resin and then binding said active material on said electricity-collector surface,
the manufacturing process for electrode for secondary battery being characterized in that said binder resin is an alkoxysilyl group-containing resin that has a structure being specified by formula (I):
wherein “R1” is an alkyl group whose number of carbon atoms is from 1 to 8;
“R2” is an alkyl group or alkoxyl group whose number of carbon atoms is from 1 to 8; and
“q” is an integer of from 1 to 100.
