Performance of the “SiO”-carbon composite-negative electrodes for high-capacity lithium-ion batteries; prototype 14500 batteries

► The silicon-based negative electrodes can be used in practical lithium-ion batteries. ► The prototype 14500 batteries show 1 Ah of nominal capacity. ► The performance is superior to the conventional batteries based on graphite. ► The batteries show neither smoke nor fire for all the tests examined.
