Title: CARBON-SILICON COMPOSITE MATERIAL, NEGATIVE ELECTRODE AND SECONDARY BATTERY
Abstract:
A carbon-silicon composite material which is suitable as a battery negative electrode material. This carbon-silicon composite material is configured such that silicon particles are present in a thermolysis product of a resin; and if this carbon-silicon composite material is immersed in an electrolyte solution ((ethylene carbonate)/(diethyl carbonate) at the volume ratio of 1/1) under the conditions of 760 mmHg, 30°C and 60 min, the absorption amount of the electrolyte solution per 1 g of this carbon-silicon composite material is 0.65-1.5 mL.
