Button cells consist of positive and negative electrode shells, active material layers, separators and electrolytes. They are packaged in an inert environment after coating and pressing. Common types include lithium-based (CR), alkaline (LR) and silver oxide batteries, which are suitable for micro devices and electrochemical testing.
Button battery preparation process: |
Mixing → coating → rolling → punching → weighing → baking → assembling → testing
Button battery assembly: |
Positive electrode shell → electrode → electrolyte → diaphragm → electrolyte → lithium sheet → support → negative electrode shell
