La Pile Leclanche, Department Piles de SAFT, 156 Avenue de Metz, Romainville 93239 Primary batteries, zinc-alkaline manganese dioxide, carbon-zinc Leclanche, lithium types (lithium-iead bisiiiuthate, lithium-silver chromate). 

Lithium batteries based on organic solvents are now made on a large scale for medical applications, back up power for computer memories, power for small electronic gadgets and the general consumer market Batteries based on four types of positive electrode (intercalation into Mn02, reduction of poly (carbon monofluoride), cupric oxide and silver chromate) are listed in Table 11.7 note that the exact solvent-electrolyte ts not specified because their selection is considered conlidential The exact composition may also vary from company to company. AH these batteries give performances markedly better than the traditional batteries (Table f 1.8). The better performance, however, is obtained...
