Title:
LEAD STORAGE CELL
Document Type and Number:
WIPO Patent Application WO/2013/031263
Kind Code:
A1
Abstract:
To clarify what sort of necessary condition based on the principles of cell reaction a charge-receiving performance is configured under, this performance being 1.5 times or more of a conventional lead storage cell, and to determine the necessary cell configuration on the basis of the clarified necessary condition. In a liquid lead storage cell in which charging is performed intermittently in short time intervals and high-rate discharge to the load is performed in a partially charged state, an electrochemical measurement system is configured by placing a reference electrode as a reference point of potential between a negative electrode panel and a positive electrode panel, the relationship between the negative electrode charging overvoltage and the positive electrode charging overvoltage and their corresponding charging currents is plotted to create a current-potential curve, and in an area where the current-potential curve is plotted resembling a straight line from a charging overvoltage of 0, the negative electrode active material of the negative electrode panel satisfies the relationship [negative electrode charging overvoltage/current] ≤ 9.4, and the positive electrode active material of the positive electrode panel satisfies the relationship [positive electrode charging overvoltage/current] ≤ 17.7.
