A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution. The positive electrode includes a positive electrode active material layer. The positive electrode active material layer includes a lithium-nickel composite oxide of a layered rock-salt type.

Positive electrode for secondary battery, and secondary battery

A battery pack supplies an electrically driven treatment apparatus with an electric driving power and includes: a first stack limiting structure and a second stack limiting structure, wherein the second stack limiting structure is disposed opposite and with a fixed distance to the first stack limiting structure; a plurality of pouch cells, wherein the pouch cells are disposed in a stack, wherein the stack is disposed between the first stack limiting structure and the second stack limiting structure and a height of the stack in a stack direction is limited by the first stack limiting structure and the second stack limiting structure; and a sensor arrangement. The sensor arrangement is disposed in the stack. The sensor arrangement extends across a major part of a surface of the pouch cells and is configured such that the height of the stack across the extension is approximately equal. The sensor arrangement has a pressure sensor. The pressure sensor is configured for detecting a pressure force acting in the stack direction on the pouch cells.
