Abstract

PURPOSE:To suppress an increase of the resistance of an electrolyte while a battery is standing alone under overdischarge conditions and reduce the charge time of a battery by adding the nitrate of alkaline metals containing sodium or alkaline rare earth metals to unwoven fabric such as glass fiber called retainer and eluting it in the electrolyte. CONSTITUTION:In a charge current curve after the convertional battery (A) stands alone under overdischarge conditions where the sodium sulphate that is eaual to 0.7wt% of the electrolyte weight is added to the conventional battery (A) and retainer, it took approximately two hours for the conventional battery (A) to reach the 1A that is cut current, but a battery (B) based on this invention to which sodium sulphate is added obtains a good result of reaching the 1A within 10min. As a result, its charge time can be reduced by 2hr.

Description

【発明の詳細な説明】 本発明は特化小形密閉式鉛蓄電池の改良１こ係り、その
目的とするところは特性向上を図る１こある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a specialized small sealed lead-acid battery, and its purpose is to improve its characteristics.

When charging after overdischarging, the charging current is difficult to flow and the charging time is long. This is overkill mih! 1
．． This is because after r1fI, almost no sulfuric acid is present in the electrolyte, and the resistance of the electrolyte increases.

In conventional battery A, it took about 2 hours to reach IA, which is a force/current, but in battery B, which added sodium sulfate according to the present invention, IA reached within 10 minutes.
Good results were obtained by reaching LC, and the charging time was able to be shortened by 2 hours. This effect is due to the addition Jllll O,I
This is seen in the range of W t 1 or more, and below this, the increase in electrolyte resistance cannot be suppressed.
