摘要： Disclosed are a battery, a battery module, a battery pack, and an electric vehicle. The battery includes a housing and at least two electrode core sets connected in series with each other and each including at least one electrode core (4). The electrode core (4) includes a positive plate, a negative plate, and an electrolyte located between the positive plate and the negative plate. The electrolyte is a solid electrolyte or a polymer electrolyte. Isolation layers (43) are arranged between opposite surfaces of two adjacent electrode core sets. Each isolation layer (43) is formed by curing an insulation adhesive coated on at least one of the opposite surfaces of the two adjacent electrode core sets.

摘要： Disclosed are a battery, a battery module, a battery pack, and an electric vehicle. The battery includes a housing and at least two electrode core sets. The housing has an accommodating cavity therein. The at least two electrode core sets are arranged in the accommodating cavity and connected in series with each other. Each electrode core set includes at least one electrode core (4). The battery further includes separators. The separators each are arranged between two adjacent electrode core sets. The separator includes a first separator (13) and a second separator (14). A gap is provided between the first separator (13) and the second separator (14).
