Embodiment Construction

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0028] A high-efficiency lead-acid battery activation method, the method includes the following steps:

[0029] S1. Pre-charge of failed battery:

[0030] S1.1. Pre-charge the failed battery once;

[0031] S1.1. After the first pre-charge is completed, let the failed battery stand for 2 to 4 hours; the charging parameters of the first pre-charge are: constant voltage of 2.3 to 2.4V / Cell, limited current of 0.1 to 0.15C 10 , Charging time is 4~24h;

[0032] S1.2. Collect the failed battery at 0.1C 10 Discharge to the capacity when the voltage is less than 1.8V / Cell, and then precharge the failed battery twice;

[0033] S2, acti...

Abstract

The invention relates to a high-efficiency lead-acid storage battery activation method. The method comprises the following steps: carrying out activation charging: carrying out a 10-hour rate initialcapacity test on a failed battery; opening a valve cover of the failed battery, and adding 0.1-1.2 mL / Ah of deionized water; carrying out 0.02-0.08 C10 low-current charging on the failed battery for 6-12 hours; and after low-current charging used for the failed battery is finished, carrying out charging for 20-60 minutes by using a positive and negative pulse process with a frequency of 50-900 HZand a current peak value of 120-300 A. The activation process disclosed by the invention mainly aims at the lead-acid storage battery of which the polar plate is sulfated, a problem that the lead-acidstorage battery fails due to an insufficient capacity caused by sulfation of the polar plate is effectively solved, a service life of the battery is prolonged, recycling of the lead-acid storage battery is greatly promoted, and cost is effectively saved.

Description

Technical field [0001] The invention belongs to the technical field of activation of lead-acid batteries, and particularly relates to a method for activation of high-efficiency lead-acid batteries. Background technique [0002] Lead-acid batteries have the characteristics of high voltage, low cost, good high-rate discharge performance, good high and low temperature resistance, easy floating charge use, and high safety. Therefore, lead-acid batteries are widely used in fields such as lighting, starting, energy storage, and backup power for communications. In the long-term use of lead-acid batteries, irreversible salinization of sulfuric acid will occur when there are long-term under-charging, long-term deep discharge at high temperature, long-term discharge, serious battery loss, and electrolyte layering, which will cause the battery capacity to decline Faster; after exploration and research, it is a relatively simple and effective activation method to remove irreversible sulfate...
