Abstract: The present disclosure provides a battery cell and a battery, wherein the battery cell comprises a battery cell body and a film casing. The film casing is wrapped around the exterior of the battery cell body. The battery cell body comprises a negative electrode plate. The negative electrode plate comprises a negative current collector and a negative active material coating. The negative active material coating comprises silicon-based material and graphite material. The film casing has a plurality of vertices, each of which comprises a first edge corner portion, a second edge corner portion, and a third edge corner portion intersected. The film casing and the battery cell body satisfy: 1500 N/m?(abc)/(Wb×Wc)?84000 N/m. The disclosure solves the technical problem that film casings are prone to damage and leakage.

Abstract: The present disclosure provides a battery cell and a battery, wherein the battery cell comprises: a battery cell body and a film casing, the film casing being wrapped around the exterior of the battery cell body, the battery cell body comprising a negative electrode plate, the negative electrode plate comprising a first current collector and a first coating, the first coating comprising graphite, the film casing having a plurality of vertices, each vertex comprising a first edge corner portion, a second edge corner portion, and a third edge corner portion intersected; the film casing and the battery cell body satisfy: 750?(abc)/(Wa×Wb×Wc)?90000. The disclosure solves the technical problem that film casings are prone to fracture and damage.
