Abstract
The invention relates to performance improvements in lead accumulators and lead-acid batteries by admixing so-called expanders or spreading materials to the active negative materials. Succinates are proposed as a new synthetic and consequently chemically clearly defined spreading means that can be used in place of lignin sulphonates, particularly iminodisuccinates or succinyl groups or oligomers containing iminosuccinyl groups or polymer compounds, individually or in any mixtures.
