Problems solved by technology

However, the internalization of tubular batteries has the problems of long internalization time, large internalization power consumption, and difficulty in internalization.
[0004] Due to the tubular structure, internalization of tubular plates is difficult, and it takes a long time for internalization, generally about 160 hours. Internalization also increases the difficulty of internalization, so it is more difficult for tubular batteries to adopt internalization.

Embodiment 1

[0075] Taking the 560Ah tubular gel battery as an example, the rapid internalization process is further described, including the following steps:

[0076] In the first step, pure water and sulfuric acid are used to mix and prepare two electrolytes with different densities for internalization, which are high-density electrolyte and low-density electrolyte; among them, the density of the low-density electrolyte is 1.03-1.05g / cm 3 , the density of the high-density electrolyte is 1.30-1.36g / cm 3 .

[0077] The second step is to pour the low-density electrolyte into the tubular colloidal battery through an acid cycle machine, let it stand for 1-2 hours, and then charge it with a small current of 5.6A to 28A for 1-2 hours.

[0078] In the third step, charge and discharge according to the charge and discharge current and time given in Table 1 below:

Abstract

The invention relates to a rapid internalization process of a tubular colloidal battery, comprising the steps of: first, preparing two electrolytes with different densities; The second step is to pourthe low density electrolyte into the battery and charge the battery at a low current of 1-2h; 3, charging and discharging in four stage, and replacing that low-density electrolyte with the high-density electrolyte in the second charging process of the second stage. As that unique internalize forming process is adopted, the difficulty of the internalizing forming is reduce, the internalizing forming efficiency is improved, and the electric energy consumed by the internalize forming is saved at the same time.

Description

technical field [0001] The invention belongs to the technical field of internal formation of batteries, and in particular relates to a rapid internal formation process of tubular colloidal batteries. Background technique [0002] Compared with the paste-coated pole plate, the outstanding advantage of the tubular pole plate is that it has a long service life, so it has been widely used in various occasions such as power, traction, fixation, and energy storage. In particular, the application of tubular gel battery technology has realized the maintenance-free and pollution-free tubular battery, making it suitable for a wider range of occasions. [0003] In the past, the internal formation of tubular plates used the method of external and internal formation. As the country’s requirements for environmental protection are getting higher and higher, the external and internal formation of the plates has been cancelled, and all plates are required to be produced using the method of i...
