specific Embodiment approach 1

[0015] Specific implementation manner one: such as figure 1 As shown, this embodiment provides an online detection device for battery electrode potential in the internal formation process of a lead-acid battery, which is composed of acid kettle 2, beaker 3, screw A 4, screw B 5, and mercury sulfate electrode C 6. This lead-acid battery is a single cell of the valve-controlled battery. The complete battery consists of several single cells connected in series with a bridge in the middle. Screw A and B are inserted into the bridge, and the edges are sealed with sealant to prevent Acid overflows during the formation process (the positive pole of this cell is also the negative pole of the upper cell, and the negative pole is also the positive pole of the lower cell). The top of the battery is an acid kettle with sulfuric acid solution. The beaker is also filled with sulfuric acid solution. The sulfuric acid system is connected by a salt bridge, and the AC terminal and the BC are resp...

specific Embodiment approach 2

[0019] Specific embodiment 2: This embodiment takes the internal formation process of the 6-DZM-12 battery as an example. The internal formation adopts a three-flush two-discharge formation method. The concentration of the sulfated solution is 1.263g / mL, the temperature is 14℃, The amount of acid injected into the grid is 189g, the concentration of sulfuric acid solution in the beaker is 1.2g / mL, press figure 1 The measuring device diagram measures the electrode potential of the battery. The effect picture is like figure 2 Shown by figure 2 It can be seen that the five electrode potential curves are basically not much different, which can indicate that the difference between the cells formed this time is small and the battery is formed better.

Abstract

The invention discloses an online detection device and a method of battery electrode level in lead-acid storage battery inner chemosynthesis process; the detection device consists of an acid kettle, a beaker, a screw A, a screw B, and a mercury sulfate electrode C; a sulfuric acid chemosynthesis solution is contained in the acid kettle; a sulfuric acid solution is contained in the beaker; the two sulfuric systems are connected via a salt bridge; the mercury sulfate electrode C is placed in the sulfuric acid solution; A-C end and B-C end are respectively connected with an electric potential measuring device. The detection steps are as follows: taking an assembled non-chemically synthesized lead-acid storage battery, inserting the screw A and the screw B on the bridge, sealing the edges with sealants; assembling the acid kettle with the battery, then adding acid; standing the battery for 1 hour after injected the acid, implementing the chemosynthesis according to the inner chemosynthesis technology; then inserting the salt bridge into the acid kettle and the beaker, and connecting a data collector for collecting data. In condition of not dissecting the battery, the electrode level in lead-acid storage battery inner chemosynthesis process can be precisely detected online, thus being convenient for understanding the chemosynthesis information, and researching the research technology.

Description

Technical field [0001] The invention relates to a device and method for measuring the electrode potential of a lead-acid battery. Background technique [0002] The traditional method of measuring the electrode potential, for the rich liquid battery, insert the cadmium rod into the electrolyte. This method is a rough method of measuring the electrode potential. During the charging and discharging of the battery, the concentration of the electrolyte changes accordingly. The electrode potential of the cadmium rod changes, so inserting the cadmium rod into the electrolyte as a reference electrode to measure the electrode potential of the battery is a relatively crude method. For lean batteries, it is even more difficult to measure the electrode potential of the battery. Summary of the invention [0003] The purpose of the present invention is to provide an online detection device and method for the electrode potential of the lead-acid battery internal formation process battery, which...
