Abstract
The present disclosure relates to lithium-ion batteries and methods for their manufacture. Specifically, the method includes forming a cathode on a first substrate and forming an anode on a second substrate. The anode material includes silicon. The method includes slitting the first substrate and the second substrate. After slitting the respective substrates, the method includes depositing stabilized lithium metal particles on the anode and forming a cathode electrode tab coupled to the cathode and an anode electrode tab coupled to the anode. The method also includes coupling the anode and the cathode to form a layered structure. The method further includes winding the layered structure to form a rolled structure and placing the rolled structure in a container. The method additionally includes placing an electrolyte in the container sealing the container with the rolled structure and electrolyte placed therein to form a battery.
