Abstract

A silicon-carbon particulate composite suitable for use as active material in a negative electrode of a Li-ion battery, a precursor composition comprising the silicon-carbon particulate composite, a negative electrode comprising the silicon-carbon particulate composite and/or precursor composition, a Li-ion battery comprising the negative electrodes, a method of manufacturing the silicon-carbon particulate composite, precursor composition, negative electrode and Li-ion battery, the use of the silicon-carbon particulate composite in a negative electrode of a Li-ion battery to inhibit or prevent silicon pulverization during cycling, for example, during 1st cycle Li intercalation or de-intercalation and/or to maintain electrochemical capacity after 100 cycles, and a device, energy storage cell, or energy storage and conversion system comprising the silicon-carbon particulate composite and/or precursor composition.
