摘要： An insulation spacer applicable to a battery cell. The battery cell further includes a shell, a first tab, and a second tab of an opposite polarity to the first tab. The first tab is insulated from the shell. The insulation spacer includes a first wall face and a second wall face opposite to each other along a thickness direction of the insulation spacer. A first hole that penetrates the first wall face and the second wall face is created on the insulation spacer. A direction from the first wall face to the second wall face is a first direction. The first hole is configured to be passed through by the first tab along the first direction and enable the first tab to bend to closely fit the second wall face.

摘要： A battery includes an electrode assembly. The electrode assembly has a population of unit cells, each unit cell including an electrode current collector layer, an electrode layer, a separator layer, a counter-electrode layer, and a counter-electrode current collector layer in stacked succession. The electrode layer has an electrode active material, and the counter-electrode layer has a counter-electrode active material. One of the electrode active material and the counter-electrode material is a cathodically active material and the other of the electrode active material and the counter-electrode material is an anodically active material. A subset of the unit cell population includes a pair of spacer members located between the electrode current collector layer and the counter-electrode current collector layer. At least a portion of the counter-electrode active material is located between the spacer members in a common plane defined by the x and z axes.
