Abstract
An electrochemical apparatus and an electronic device, the electrochemical apparatus including a housing, an electrode assembly, and a first electrode. The housing includes a first part and a second part that are interconnected, where the electrode assembly is accommodated in an accommodating cavity of the first part. The first electrode includes a first inserting portion and a first flange portion, where the first flange portion and the first inserting portion are integrally formed, the first flange portion embeddedly snap-fits into the second part, the first flange portion is connected to the electrode assembly, and the first inserting portion extends away from the accommodating cavity and protrudes from an outer surface of the second part.
Claims16
An electrochemical apparatus, comprising a housing, an electrode assembly, and an electrolyte;
- wherein the housing comprises a first part and a second part interconnected to each other, the electrolyte is stored in the housing, the first part encloses an accommodating cavity, and the electrode assembly is accommodated in the accommodating cavity;
- and the electrochemical apparatus further comprises a first electrode,
- wherein the first electrode comprises a first inserting portion and a first flange portion, wherein the first flange portion and the first inserting portion are integrally formed, the first flange portion embeddedly snap-fits into the second part, the first flange portion is connected to the electrode assembly, and the first inserting portion extends away from the accommodating cavity and protrudes from an outer surface of the second part,
- wherein the electrochemical apparatus further comprises a second electrode, the second electrode being spaced apart from the first electrode;
- and
- the second electrode comprises a second inserting portion and a second flange portion, wherein the second flange portion and the second inserting portion are integrally formed, the second flange portion embeddedly snap-fits into the second part, the second flange portion is connected to the electrode assembly, and the second inserting portion extends away from the accommodating cavity and protrudes from the outer surface of the second part, and
- wherein the first flange portion satisfies at least one of the following conditions:
