Problems solved by technology

[0003] In the history of storage battery production, the method to solve the excess plates has always been passive methods, either returning to the furnace, or deliberately installing an extra plate when assembling against the principle of the battery, or artificially forming in violation of electrochemical requirements. It is unreasonable and unscientific to install the same number of cathode and anode raw plates in the electrolyzer

Embodiment 1

[0033] Example 1: replace the anode plate with a grid to install the tank, and the cathode is the cathode plate, according to the density of the electrolyte 1.05±0.005 (15°C), the formation current 2.5A / single piece (based on the positive plate), the formation Voltage ≤ 155V, formation time 28 hours, negative plate rinsed with clean water for 2 hours, soaked in 5% glycerin for 15-20 minutes, drying temperature 90-95°C under the conditions of formation, the cathode plate produced alone contains PbO7.13%, low Based on the internal control standard of PbO ≤ 9%, the formation cost is 0.26 yuan / single piece.

Embodiment 2

[0034] Embodiment 2: replace the anode plate with the grid to load the tank, the cathode is the cathode plate, except that the formation time is changed to 30 hours, other formation conditions are formed according to the embodiment 1, and the cathode plate is produced separately containing PbO5.72 %, which is lower than the internal control standard with PbO≤9%, and the formation cost is 0.27 yuan / single piece.

Embodiment 3

[0035] Embodiment 3: replace the anode plate with the grid to install the tank, the cathode is the cathode plate, except that the formation time is changed to 34 hours, other formation conditions are formed according to the embodiment 1, and the cathode plate is produced separately containing PbO4.33 %, lower than the internal control standard with PbO≤9%, and the formation cost is 0.30 yuan / single piece.

Abstract

The invention relates to a balanced tie-in manufacturing method of negative and positive plates of the storage batteries. It replaces the positive plates with the slab lattices to produce the negative plates alone or replaces the negative plates with the slab lattices to produce the positive plates alone. When the positive plates are superfluous during producing the storage battery, replace the anode plates with the slab lattices, take the cathodes as the negative plates and produce the negative plates alone with between 4.33% and 7.13% of PbO in normal formation condition. When the negative plates are superfluous, replace the cathode plates with the slab lattices, take the anodes as the positive plates and produce the positive plates alone with between 77.68% and 85.21% of PbO2 in normal formation condition. By adopting the invention to produce the negative and positive plates, can get stable index, reliable technology, pay the cost of between 0.26RMB and 0.30RMB per monolithic for the profit of more than 1RMB pre monolithic and is a good method of balanced arrangement of the negative and positive plates of the storage batteries and increasing the benefit.

Description

(1) Technical field [0001] The invention relates to a production method for the balanced production of cathode and anode plates of a storage battery, in particular to a method of replacing anode plates with grids for chemical formation and producing cathode plates alone; (2) Background technology [0002] In the battery production process, usually only one more anode plate (double sheet) is produced in each formation tank, that is, only two more anode plates are produced in each tank. When assembling the storage battery, it is often artificially assembled according to the ratio that each electrode group has one more cathode plate than the anodized one. For a battery with six electrode groups, the cathode plate uses 6 more cathode plates than the anode plate. Over time, resulting in production The matching of cathode and anode plates in the process is unbalanced, and there is a phenomenon of excess anode plates and insufficient cathode plates. Thes...
