Multicell battery having double adhesive liquid sealing window
Abstract
Abstract AROUND EACH CELL OF A MULTICELL BATTERY IS A WINDOW, BOTH SIDES OF WHICH ARE ADHESIVE. THE ISIDE PERIMETER OF EACH WINDOW, WHICH OVERLAPS A PORTION OF THE INTERCELL CONNECTOR BETWEEN TWO ADJACENT CELLS, PROVIDES A FIRST SEAL AROUND A CELL TO PREVENT LIQUID FROM ONE CELL FROM MIGRATING EITHER OT ANOTHER CELL OR TO THE EXTERIOR OF THE BATTERY. THE OUTSIDE PERIMETER OF EACH WINDOW EXTENDS BEYOND THE EDGES OF THE INTERCELL CONNECTOR TO PROVIDE A SECOND SEAL WHICH ALSO PREVENTS LIQUIDS FROM MIGRATING FROM THE INTERIOR TO THE EXTERIOR OF THE BATTERY. THE WINDOWS MAY BE ELECTRICAL INSULATORS WHICH SERVE THE ADDITIONAL FUNCTION OF KEEPING ELECTRICALLY CONDUCTIVE INTERCELL CONNECTORS AND/OR LIQUID IMPERVIOUS LAYERS FROM COMING INOT ELECTRICAL CONTACT WITH EACH OTHER.
