Batteries and electronic devices
This disclosure relates to a battery and an electronic device, wherein the battery includes a negative electrode and a positive electrode. The negative electrode and the positive electrode are stacked. The positive electrode has multiple bent concave-convex structures. By providing multiple concave-convex structures on the positive electrode, the gap between the positive electrode and the negative electrode is increased, providing space for the expansion deformation of the negative electrode when it expands, thereby preventing the battery as a whole from expanding.

Noise-reducing inductor
ActiveCN222637029Uincrease gap distanceavoid mechanical noiseTransformers/reacts mounting/support/suspensionTransformers/inductances coils/windings/connectionsInductorMechanical engineering
The utility model discloses an inductor capable of reducing noise. The inductor is welded and assembled with a PCB (Printed Circuit Board) through electrode pins. As an improvement key point, air gap grooves are formed in gap areas of all electrode pins at the bottom of the inductor, and the distance between the air gap grooves and the surface of a PCB is increased. The inductor can be realized by arranging a groove at the bottom of the inductor or adjusting bending parameters of electrode pins. According to the inductor, on the premise that the inductor and the PCB are welded and assembled normally, the gap distance between the bottom of the inductor and the surface of the PCB is increased, the amplitude of the inductor when large current passes through is eliminated, and mechanical noise caused by direct beating of the PCB is avoided. The sensor can be better applied to CPU / GPU power supply hardware manufacturing of hot industries such as AI artificial intelligence / big data / cloud service.
