Abstract

An electrochemical apparatus and an electrical device, where the electrochemical apparatus includes a housing, an electrode assembly, and an adhesive component. The housing includes a first sidewall, and the electrode assembly is disposed within the housing and includes a first side surface adjacent to the first sidewall, where the first side surface includes a second region, a first region, and a third region arranged sequentially along a first direction. The adhesive component is located between the housing and the electrode assembly, where the adhesive component includes a first surface and a second surface opposite to each other; the first surface includes a first adhesive zone bonded to the first sidewall; the second surface includes a second adhesive zone bonded to the second region, a third adhesive zone bonded to the third region, and a first non-adhesive zone located between the second adhesive zone and the third adhesive zone. Along a second direction, a projection of the first adhesive zone overlaps with the first non-adhesive zone, where the second direction is a direction in which the first sidewall is opposite to the first side surface. By eliminating bonding of the adhesive component to the first region, the present application helps reduce a risk of damage to the electrode assembly.
