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.
