Abstract: The present disclosure provides a method for manufacturing a unit cell including the steps of: preparing an electrode and a separator individually, wherein the separator includes a porous polymer substrate and a porous coating layer disposed on at least one surface of the porous polymer substrate and including a mixture of inorganic particles with a binder polymer; applying a lamination solvent to the surface of the separator to be bound with the electrode; and carrying out lamination of the electrode with the separator before the lamination solvent is dried. The method according to the present disclosure can solve the problem of shrinking of a separator occurring in the conventional lamination process.

Abstract: An inorganic platelet composition for use as electrical insulation, thermal insulation and fire protection for electrochemical cells such as lithium ion cells. The inorganic platelet composition may be applied directly to the exterior surfaces of the housings of one or more individual battery cells within a battery module and/or larger battery pack, and/or to the surfaces of the battery module or battery pack housing, and/or to structure surrounding the batteries, battery modules or battery packs that would benefit from electrical insulation and fire protection. The inorganic platelet composition can minimize or prevent thermal runaway events that may originate from one battery cell or within modules of battery cells from propagating to adjacent or nearby cells, modules, packs or other structures.
