An electrode for a secondary battery according to exemplary embodiments includes an electrode current collector; an electrode active material layer formed on the electrode current collector; and a coating layer formed on the electrode active material layer and including rod-shaped inorganic particles and spherical organic particles, wherein a ratio of a length of major axis of the rod-shaped inorganic particle to a length of diameter of the spherical organic particle may be 3 to 5.

Electrode for secondary battery and lithium secondary battery including the same

An exemplary embodiment in the present disclosure relates to an electrode assembly capable of suppressing the occurrence of a short of a battery including an insulation film, a secondary battery including the electrode assembly, a battery module, and a battery pack. The electrode assembly includes an electrode laminate in which a cathode and an anode are alternately stacked with a separator as a boundary, a porous insulation film surrounding four or more sides of the electrode laminate, in which two of both ends of the insulation film are adhered on a side surface of the electrode laminate.

Electrode assembly preventing internal short, secondary battery comprising the same, battery module and battery pack

A battery cell includes an electrode assembly in which a plurality of electrode plates are stacked; a protective assembly disposed on at least one side of the electrode assembly and including an insulating material; and a case having an internal space in which the electrode assembly is accommodated, wherein the protective assembly includes a through-hole configured to allow electrolyte to pass therethrough.

Battery cell

A secondary battery cell includes: a case in which an electrode assembly is accommodated; a cap plate assembly coupled to at least one side of the case; and a venting unit including a base coupled to one surface of the case and a notch portion formed on the base, and the notch portion includes: a first notch portion extending in a first direction; a second notch portion extending in a second direction intersecting the first direction; and a third notch portion extending in a third direction, parallel to a longitudinal direction of the base from both ends of the first notch portion and the second notch portion.

Secondary battery cell
