摘要： The invention provides a negative electrode material for use in a rechargeable battery, comprising a Si based material comprising a mixture of submicron sized Si particles and submicron sized Si wires, wherein the average particle size of the Si particles is at least twice the average width of the Si wires, preferably at least 5 times, and most preferably at least 10 times the average width of the Si wires. The process for manufacturing these Si based materials comprises the steps of: providing a Si based precursor, providing a gas stream at a temperature above the atomization point of the Si precursor, injecting the Si precursor in the gas stream, quenching the gas stream carrying the vaporized Si precursor, thereby obtaining a mixture of submicron sized Si particles and submicron sized Si wires, and separating the mixture from the gas stream.
