SiO _x -based graphite composite anode and efficient binders: practical applications in lithium-ion batteries.

ABSTRACT: In recent years, graphite containing some proportion of SiO _x -based materials for lithium-ion batteries has been investigated widely owing to its high specific capacity. An efficient binder is critical to maintain both the electronic and mechanical integrity of the SiO _x -based graphite composite anode electrodes. In this study, we present a discussion on the water-soluble binders of styrene butadiene rubber (SBR) and poly acrylic acid (PAA) in a 15% SiO _x -graphite composite anode with half cell (coin) and high voltage pouch battery. The peeling strength of the anode electrode using two binders was measured. The first coulombic efficiency and discharge specific capacity of SiO _x -graphite was 83.6% and 626.5 mA h g
