Description

 The invention relates to the regeneration of chemical current sources - starter lead storage batteries (AB).

 A known method of improving the electrical characteristics of an electrolyte of a chemical current source by processing in a magnetic field / 1 /. This method is complex and inefficient.

 The closest in technical essence and the achieved results is a way to improve the electrical characteristics of the electrolyte for lead starter batteries by wave acoustic impact on the electrolyte / 2 /. During this treatment, electrolyte molecules are relaxed in large cluster compounds, limiting their mobility in the pores of spongy lead electrodes. The low mobility of the electrolyte ions, especially at low temperatures, reduces the surface contact area of the electrode material with the electrolyte, which leads to an increase in charge duration and a decrease in battery power.

 The objective of the invention is to reduce the duration of the charge and improve electrical characteristics.

 This is achieved by the fact that in the method of improving the electrical characteristics of the electrolyte for starter lead ABs, which includes a wave action on the electrolyte, according to the invention, the action is carried out by a laser beam with a wavelength of 1.06 μm and a power of 45 50 W, while the electrolyte is fed into the exposure zone in the form metered laminar stream with a constant speed.

 Example 1. The electrolyte stream was treated with a laser beam with a wavelength of 1.06 μm and a power of 45 W, after which AB was filled with this electrolyte. The duration of the charge was reduced by 3 hours, the voltage increased after 30 s from the beginning of the discharge with a current of 610 A by 1.6 V; the duration of the discharge to the final voltage increased by 1.8 min; the final voltage at the terminals increased by 1.5 V.

 Example 2. Under the conditions of example 1, a laser power of 50 W was taken. The duration of the charge was reduced by 3 hours, the voltage increased after 30 s from the beginning of the discharge with a current of 610A by 1.4 V; the duration of the discharge to the final voltage increased by 1.7 min; the final voltage at the terminals increased by 1.5 V.

 Example 3. The processing of the jet of electrolyte was carried out by a laser beam with a wavelength of 0.355 μm and a power of 35 W, after which the electrolyte was filled in with AB. The results showed that the duration of the charge was reduced by 0.8 h, the voltage increased after 30 s from the beginning of the discharge with a current of 610 A by 0.6 V; the duration of the discharge to the final voltage increased by 0.5 min; the final voltage at the terminals increased by 0.6 V.

 Using the proposed method provides an improvement in the electrical characteristics of lead starter batteries by 7 27% and reduces the duration by 20 27%
