Abstract

An anode electrode comprises an anode current collector. An anode active material layer comprises anode active material comprising at least one of lithium silicon oxide, silicon oxide, lithium silicon oxide and graphite, and silicon oxide and graphite. The anode active material layer further comprises a binder comprising a mixture of styrene butadiene rubber (SBR), sodium carboxymethyl cellulose (NaCMC) and sodium polyacrylic acid (NaPAA), wherein SBR comprises greater than 60% wt of the binder.
