Abstract
Methods of recycling silicon from lithium-ion batteries having silicon-based electrodes are disclosed. Batteries and methods of manufacturing batteries from the recycled silicon are also disclosed. A method of recycling may include discharging each of one or more batteries to below a threshold voltage and disassembling each of the one or more batteries to collect source material from silicon-based electrodes of the one or more batteries. The source material may include silicon from the silicon-based electrodes. The method may further include rinsing the source material in alcohol to obtain a solution and extracting recycled silicon from the solution by heating the silicon for a first period of time and leaching the silicon in an acid for a second period of time. In some methods, the heating occurs before the leaching. In other embodiments, the leaching occurs before the heating.
