Industrial Batteries

To attain even higher cycling performance from lead–acid batteries, further improvement of the positive active-material is needed. For industrial batteries used in heavy cycling operations, the service-life is often limited by the degradation of the positive active-material. To overcome this problem, the depth-of-discharge has to be restricted, sometimes even to 50%. Accordingly, larger batteries are required.

The softening process of the positive material of lead–calcium plates has already been repressed significantly. In principle, however, there appears to be no reason why the softening cannot be slowed down even more. Ideally, in the dissolution–precipitation process, the lead dioxide should be deposited exactly at the place from which it had previously dissolved so that no change in crystalline structure would occur. Advantageous additives and ingenious paste recipes and plate processing may prove useful in achieving such a condition.

The enhanced flooded battery (EFB) has been introduced for micro-hybrid applications. The EFB combines outstanding cold-cranking power with very good charge-acceptance and excellent cycle-life. In addition to various improvements of the negative plate, some optimization of the positive active-material has been achieved. A couple of years ago, many in the battery community doubted that automotive flooded lead–calcium batteries would ever deliver such a high overall level of performance. The success of the EFB confirms that a significant enhancement of lead–acid batteries is still possible, and indeed is essential as car manufacturers will make even greater demands on the technology as vehicles become progressively electrified. Although much work is currently devoted to improving the negative plate, the positive plate should not be neglected.
