The binder effect on an oxide-based anode in lithium and sodium-ion battery applications: the fastest way to ultrahigh performance.

A positive effect of the polyacrylic acid (PAA)-carboxymethyl cellulose (CMC) binder to enhance the performance of an oxide-based anode was reported in batteries. A series of super high capacity and cycling ability oxide powders rarely achieved before was obtained, particularly most of them without any specific carbon modification and/or morphology control.
