Square carbon battery

The invention discloses a square carbon battery, and the battery comprises an insulating shell; a shell cover is arranged at the upper end of the insulating shell, the interior of the insulating shellis divided into a plurality of battery bins through a plurality of partition plates, dry batteries are placed in the battery bins, and the negative electrode of the front dry battery is connected with the positive electrode of the rear dry battery through a connecting piece in the direction from left to right of the dry batteries. The negative electrode housing of each dry battery is arranged tobe exposed. One end of the connecting piece is connected with the positive electrode, the other end of the connecting piece bypasses the partition plate, is inserted between the adjacent dry battery and the inner wall of the corresponding battery bin and is connected with the side wall of the negative electrode shell of the dry battery, the partition plate is higher than the side wall of the dry battery, and the lower end
