The present disclosure relates to a horizontal composite electricity supply structure, which comprises a first insulation layer, a second insulation layer, two electrically conductive layers, and a plurality of electrochemical system element groups. The two electrically conductive layers are disposed on the first and second insulation layers, respectively. The electrochemical system element groups are disposed between the first insulation layer and the second insulation layer, and connected in series and/or in parallel via the electrically conductive layers. The electrochemical system element group is formed by several serially connected electrochemical system elements. Each electrochemical system element includes a package layer on the sidewall, so that their electrolyte systems do not circulate with one another. Thereby, the high voltage produced by connection will not influence any single electrochemical system element nor decompose their respective electrolyte systems. Hence, serial and/or parallel connections are made concurrently in the horizontal composite electricity supply structure.

A battery module and a method of assembling a battery module are provided. The method includes selectively applying a light-cure adhesive to recesses in a first side of a carrier layer and inserting battery cells into respective recesses. The method further includes exposing the first side of the carrier layer to light to at least partially cure the light-cure adhesive with the carrier layer in a first orientation, moving the carrier layer into a second orientation, and exposing a second opposite side of the carrier layer to light to fully cure the light-cure adhesive. The recesses may include a sidewall having crush points spaced apart along the sidewall and a bottom portion having an opening between a pair of crush points, where adhesive is not disposed between the pair of crush points.
