Abstract

The invention relates to a storage battery, which is formed by serially connecting unit batteries, wherein positive plates and negative plates of the unit batteries consist of slab lattices and positive and negative active materials filled therein, each unit battery has a cuboid structure packaged by stacking the positive plate, a clapboard and the negative plate in turn and filling a high molecular material, each unit battery and the peripheral unit batteries are connected into a whole body in a seamless mode, and the unit batteries are put on a plane parallel with a plate electrode in a good order in turn to form a unit battery layer, and simultaneously form a multi-layer structure in the direction vertical to the plate electrode; and the preparation method comprises the steps of moduledesign, slab lattice preparation, module preparation, battery assembly and battery formation. The storage battery and the preparation method have the following advantages that: the preparation process is simple and the cost is saved; the volumetric specific energy of the battery is improved, the internal resistance of the battery is reduced, the heavy-current discharge performance of the battery is improved, a cantilever beam structure is arranged in the battery, and the battery is vibration-resistant; and the internal pressure of the battery can be increased to improve the oxygen recombination efficiency and prolong the service life of the battery.

Description

technical field [0001] The present invention relates to a secondary battery (storage battery) and its manufacture, in particular to a new concept of storage battery composition, an overall manufacturing method of the battery, a connection method between cells, and a storage battery with a unique structure formed by the method. Background technique [0002] The prior art involves the connection between cells of the storage battery and the manufacturing method of the storage battery. Generally, one of the following processes is adopted: [0003] The first method: grid manufacturing--pasting--curing, drying--plate formation--drying--combining separators and positive and negative plates-- ----Welding pole group, connecting pole and lead-out pole (various poles are manufactured separately)-----The pole group is put into the battery slot (battery slot and cover are manufactured separately)------Each unit Through-wall welding connection or cross-bridge welding connection between g...
