Abstract
A pressing machine includes pressing devices, actuators and a control module. At least one of the pressing devices includes a surface having a fluoropolymer material. At least one of the actuators is configured to adjust pressure of the pressing devices on one or more lithium foils, such that the surface presses against one of the one or more lithium foils to form a protective layer. The control module is configured to control the at least one of the actuators to adjust a parameter to control at least one of thickness of the protective layer and fluoride content of the protective layer.
