LEAD BATTERY AND STORAGE METHOD FOR LEAD BATTERY Russian patent published in 2009 - IPC H01M10/06 H01M10/42 

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of electric engineering specifically to lead accumulator batteries (AB). In this invention lead AB is suggested which becomes operative by means of filling it with ionogen. AB comprises positive and negative electrode plates each one of which has grid that contains alloy on the base of Pb-Ca; separators that isolate positive electrode plates from negative electrode plates; ionogen containing sulphuric acid; and accumulator container accommodating positive and negative electrode plates, separators and ionogen. Accumulator container is sealed and part of positive and negative electrode plates is immersed into ionogen. Y₀ height of positive and negative electrode plates and Y₁ distance from positive and negative electrode plates bottom to ionogen level satisfy relation: 15 ≤ Y₁/Y₀ × 100 ≤ 60.

EFFECT: lowering of self-discharge during storage and charging frequency.
