Method of sealing a collation of battery layers together

摘要

The method, which provides liquid-impervious seals around opposed positive and negative battery electrodes in a collation of battery layers, concerns the need to apply energy around the opposed electrodes by some means other than and for a longer time period than the conventional pair of pressure rolls which have previously been used to seal moving battery layers. With this invention the seals are made by platens which either travel along with the moving collation during the sealing step or which are brought into contact with an increment of the collation which is temporarily stopped.
