BATTERY CELL COMPRISING ELECTRODE COATED WITH INACTIVE PARTICLES

摘要

The present invention relates to a battery cell having an electrode assembly, which is impregnated with an electrolyte liquid and is embedded in a variable cell case, and being flexibly deformable according to the shape of a device on which the cell is mounted, and more specifically, a battery cell whose most bottom or top electrode in the electrode assembly with respect to the stacking direction of the electrode, being characterized in that a coating part comprising inert particles is formed on an electrode composite layer corresponding an inner side of the cell case.
