Problems solved by technology

However, the method of attaching the insulating tape 60 requires additional costs and processes, and if the attachment position is not suitable, there is still a possibility of contact
In addition, since the adhesive strength of the insulating tape 60 cannot be maintained permanently, the insulating tape 60 is easily detached.

Abstract

A battery module according to one embodiment of the present invention comprises: a battery cell stack in which a plurality of battery cells are stacked; a bus bar frame connected to the battery cell stack; cell terraces protruding from adjacent battery cells among the battery cells included in the battery cell stack; electrode leads protruding from the cell terraces, respectively; and an insulating adhesive layer positioned between adjacent electrode leads among the electrode leads and covering a boundary portion between the cell terraces and the electrode leads, wherein the insulating adhesive layer is in close contact with a step formed by the cell terraces and the electrode leads.

Description

Technical field [0001] Cross-reference related application [0002] The present application claims priority to Korean Patent Application No. 10-2019-0028249 submitted to the Korean Intellectual Property Office on March 12, 2019, which is incorporated herein by reference. [0003] The present disclosure relates to a battery module and a method of manufacturing the same, and more particularly to a battery module to prevent stability problems caused by unexpected electrical connections and a manufacturing method thereof. Background technique [0004] Secondary batteries are easily applied to a variety of product groups and have electrical properties such as high energy densities, which are not only widely used in portable devices, but also widely applied to electric vehicles (EVs) or mixing vehicles driven by electric drive source. (HEV), energy storage system, etc. Because there is a significant reduction in the main advantages of fossil fuel use, it does not produce any by-produc...
