【課題を解決するための手段】鉛蓄電池劣化の主要因

電池は'寿命'とされ、廃棄されてきた。The main cause of the deterioration of the lead-acid battery is the sulfation (lead sulfate PbS
O 4 ) is a known fact. Lead acid batteries are
The negative electrode (Pb) and the positive electrode (PbO 2 ) are in the electrolyte solution (2H 2 SO 4 ), and charge and discharge are repeated.Sulfation (lead sulfate P
The occurrence of bSO 4 ) is inevitable. Sulfation (lead sulfate
PbSO 4 ) is an ionic crystalline solid deposited on the electrode surface,
Since it does not have electron conductivity and ionic conductivity, it becomes a non-conductive film on the electrode surface, and the capacity of the lead storage battery is reduced, and the performance is degraded. The lead-acid battery has been used for about three years, and its life has been expired.

2-の形で電解液(H2SO4)に還元させ、電極の充放電能力
を回復させることが必要である。[0005] Since sulfation (lead sulfate PbSO 4 ) has sulfate ions (SO 4 2- ) in the crystal, even if the lead storage battery is charged, the sulfate ions (SO 4 2- ) are converted into the electrolyte solution (H 2 Not reduced to SO 4 ). Therefore, H 2 O in the electrolytic solution is relatively increased with respect to SO 4 2− , and the specific gravity of the electrolytic solution is reduced.
This is why the specific gravity of the electrolyte is measured in order to indirectly grasp the performance state of the lead storage battery. In order to restore the degraded lead-acid battery performance, sulfation deposited on the electrode surface (lead sulphate PbSO 4) and molecular decomposition, SO 4
It is necessary to reduce the electrolyte (H 2 SO 4 ) in the form of 2- to restore the charge / discharge capability of the electrode.

必要がある。It is a known fact that sulfation (lead sulfate PbSO 4 ) is molecularly decomposed by applying a DC pulse to a lead-acid battery electrode. However, the decomposition rate of sulfation by the DC pulse varies depending on the specification of the lead storage battery to be processed, the degree of deterioration (the amount of sulfation and the degree of crystallization), and the temperature during processing. Therefore, in order to efficiently decompose the sulfation, it is necessary to optimally set the pulse waveform, the wave height, the duty ratio (current duration ratio at the maximum amplitude) and the charging current value in accordance with the fluctuation factors.

The term “appropriate charging” as used herein refers to repetition of charge / discharge having an optimal current value and an optimal interval in accordance with the standard, the degree of deterioration, and the temperature during processing of a lead storage battery to be processed.
