| Zusammenfassung: | The invention relates to a novel valve-control type lead-acid storage battery for an electric vehicle. The novel valve-control type lead-acid storage battery for the electric vehicle in a storage battery is characterized in that a negative plate grid in the lead-acid storage battery comprises a quaternary alloy including the following components: 0.06-0.09% of Ca, 1.0-1.2% of Sn, 0.015-0.035% of Al, and the rest of Pb; and a positive plate grid in the lead-acid storage battery comprises a quaternary alloy including the following components: 0.06-0.09% of Ca, 0.5-0.7% of Sn, , 0.015-0.035% of Al, and the rest of Pb. The invention further comprises limitation of diachylon components and contents of positive and negative plates, and preparation of the lead-acid storage battery. By means of the novel valve-control type lead-acid storage battery for the electric vehicle disclosed by the invention, the battery grouping utilization consistency and deep circulation service life problems can be radically resolved.
