The present application provides an electrochemical apparatus and an electric device. The electrochemical apparatus includes a housing and an electrode lead-out assembly, a first through hole is provided on a wall portion of the housing, the electrode lead-out assembly includes an electrode terminal, a connecting piece, and at least one sealing member, the connecting piece is a metal piece, the connecting piece is connected to the wall portion, a second through hole is provided on the connecting piece, the electrode terminal runs through the second through hole, and the sealing member is disposed between the connecting piece and the electrode terminal. This can reduce the processing difficulty of the electrode lead-out assembly, improve the versatility of the electrode lead-out assembly, and enhance the sealing effect of the electrochemical apparatus.

An electrochemical device and an electronic device are disclosed. The electrochemical device includes a housing, an electrode assembly, a first conductive plate, a first layer, and a second layer. The housing includes a first wall and a side wall. The electrode assembly is a wound structure and includes a first electrode sheet. The first conductive plate includes a first conductive area and a second conductive area, connected to the first electrode sheet and the first wall, respectively. The second conductive area extends in a second direction and includes a first end portion connected to the first conductive area and a second end portion opposite the first end portion. In a first direction, the first layer is disposed between the electrode assembly and the second conductive area. When viewed from the first direction, the first layer includes a first side extending in a curved manner along an edge of the electrode assembly and a second side connected to the first side, where the second side overlaps with the electrode assembly, and the second side is farther from the edge of the electrode assembly than the first side to form a notch. When viewed from the first direction, the second end portion overlaps with the first layer, and a first area of the second layer overlaps with the first layer. This application can improve reliability and service life.

A battery and an electric device are provided. The battery includes an electrode assembly, a housing, and a terminal post, where the electrode assembly is accommodated in the housing. The housing includes a first wall and a second wall disposed opposite each other along a first direction and includes a peripheral side wall surrounding the first wall and the second wall and disposed therebetween. The first direction is a thickness direction of the battery. The first wall includes a reinforcement portion, where the reinforcement portion protrudes beyond the peripheral side wall. The peripheral side wall includes a top wall and a bottom wall disposed opposite each other along a second direction, where the top wall is provided with a through-hole, and the terminal post is disposed at the through-hole. In the above battery, the reinforcement portion protrudes beyond the peripheral side wall. During battery swelling, the reinforcement portion can suppress formation of creases at an edge of the first wall, reduce pulling on the peripheral side wall, and provide support to the peripheral side wall, enhancing structural strength of the peripheral side wall, improving resistance of the peripheral side wall to tensile deformation, thereby reducing a risk of collapse of the peripheral side wall and improving safety performance of the battery.

This application discloses a separator, an electrochemical device, and an electronic device. The separator includes a separator substrate, a first coating layer, and a second coating layer. The separator substrate includes a first surface and a second surface disposed opposite to each other. The first surface faces a positive electrode, and the second surface faces a negative electrode. The first coating layer is disposed on the first surface, and the second coating layer is disposed on the second surface. The first coating layer is a dense solid filler coating. A porosity of the first coating layer is denoted as D<1>, satisfying: 10% ≤ D<1> < 30%. The second coating layer is a high-porosity solid filler coating. A porosity of the second coating layer is denoted as D<2>, satisfying: 30% ≤ D<2> ≤ 60%. By disposing two coating layers of different performance parameters on two sides of the separator, this application improves the cycle performance, low-temperature discharge performance, and heat resistance of the battery.
