Abstract
The present disclosure provides particulate electrode active material composite capable of alleviating the influence of expansion and contraction of silicon during charging and discharging of a battery, an electrode mixture including such particulate composite, and a battery including such an electrode mixture. The particulate electrode active material composite of the present disclosure is formed of a plurality of silicon particles and a carbon material binding the plurality of silicon particles to each other. In the particulate electrode active material composite of the present disclosure, the G/D ratio of the carbon material is 0.2 or more in a Raman spectrum, and/or the C=O/C-O area ratio and/or the C=O/C-O intensity ratio of the carbon material is 5.0 or less in an XPS spectrum.
