Abstract
A secondary electric cell which includes: a non-aqueous electrolyte, a negative electrode whose active material includes at least one alkali metal in contact with the electrolyte, and a positive electrode whose active material is suitable for intercalating the active material of the negative electrode, wherein said positive electrode includes an active compound or solid solution whose general formula is M.sub.x X, R.sub.y X.sub.3 where: PA0 M is an element chosen from lead and tin; PA0 R is an element chosen from bismuth and antimony; and PA0 X is an element chosen from sulphur and selenium, with x having a value lying between 0 and 1 (inclusive), and y having a value lying between 0 and 2 (inclusive). Such cells may be used in watches or pacemakers.
