Abstract
A lower plastic assembly, an end cover assembly, an energy-storage apparatus, and an electronic device are provided in the disclosure. The lower plastic assembly includes a first lower plastic member. The first lower plastic member comprises a first-lower-plastic-member body. The first-lower-plastic-member body has a first top surface and a first bottom surface opposite the first top surface, and further comprises a first part, a second part, and a first deformation portion. The first deformation portion is located between the first part and the second part in a length direction of the first-lower-plastic-member body. A ratio of a depth h1 of the first deformation portion to a height h2 of the first part ranges from 0.05 to 0.42 in a thickness direction of the first-lower-plastic-member body. A ratio of the depth h1 of the first deformation portion to a height h3 of the second part ranges from 0.16 to 0.6.
