Abstract
An electrode binder for use with rechargeable batteries is disclosed. In embodiments, the electrode binder comprises a styrenic block copolymer (SBC) for use with an electrode active material, such as Si, Si alloys, Si compounds, Si composites, carbon black, or graphite in an amount of at least 20 wt. %. The SBC can be unsaturated (USBC) or hydrogenated (HSBC), or functionalized, wherein functionality includes maleation, epoxidation, silanation, carboxylic acid/salt, quaternary ammonium salt, sulfonation and others. In embodiments, the electrode binder is selected from isoprene rubber (IR), silicone-containing block copolymer, and an electronically conductive block copolymer containing a block that is unhydrogenated CHD (cyclohexadiene) block.
