Electrochemical cell having container with embedded positive electrode current collector |
摘要 |
An electrochemical cell has a container containing a positive electrode, a negative electrode, and an electrolyte. The container has a bottom face and a hole formed in the bottom face. A positive electrode current collector is embedded in the bottom face of the container so that the hole formed in the bottom face exposes a portion of the positive electrode current collector. A covering portion is adhered to the positive electrode and covers the exposed portion of the positive electrode current collector. The positive electrode current collector is electrically connected to the positive electrode via the covering portion. A lid seals the container.
