Abstract:
An electrochemical cell, which comprises:a) a casing comprising a container having a container opening closed by a lid secured to the container, wherein the container and lid provide the casing having a casing side wall with a casing opening allowing for access into the casing interior; b) a negative electrode of a negative electrode active material which intercalates and deintercalates with an alkali metal; c) a positive electrode comprising a positive electrode active material which intercalates and deintercalates with the alkali metal; and d) an electrolyte solution activating the negative and positive electrodes, wherein the casing opening provides fluid flow communication between the casing interior and a gas release device that selectively provides for cell gas inside the casing to vent to outside the casing.
