The present application discloses a negative electrode, a secondary battery and a device comprising the same. The negative electrode includes: a current collector; a first active material layer close to the current collector, the first active material layer including a first active material; and a second active material layer disposed on a surface of the first active material layer away from the current collector, the second active material layer including a second active material; wherein the first active material and the second active material are independently oval-like particles with through holes and/or blind holes, and the first active material has an average pore size greater than that of the second active material.

Negative electrode, secondary battery and device comprising same

The present application provides a mounting base, a battery and a power consuming device, which relate to the technical field of batteries. The mounting base may be configured to be connected to an end plate and an output electrode, and an insulating structure may be provided on one side of the end plate and configured to insulate the end plate from a battery cell. The mounting base may include a main body provided with a flow guiding groove on the side facing the insulating structure. The flow guiding groove may be configured to prevent an electrical connection between the output electrode and the end plate by means of a liquid between the main body and the insulating structure.
