The invention relates to secondary alkaline electrochemical generators with a zinc anode in an electrolyte, the active mass of said anode comprising at least one conductive ceramic. According to the invention, the electrolyte of the generator is made up of a highly-concentrated alkaline solution and/or the active mass of the zinc anode contains an additive comprising at least one alkaline titanate having general formula (M<SUB>2</SUB>O)<SUB>n</SUB>(Ti)<SUB>2</SUB>)<SUB>m</SUB>xH<SUB>2</SUB>O, wherein M denotes Li, Na, K, Rb or Cs, n being between 0.5 and 2, m being between 1 and 10 and x being between 0 and 10, or alkaline earth having general formula (MO)<SUB>n</SUB>(TiO<SUB>2</SUB>)<SUB>m</SUB>xH<SUB>2</SUB>O, wherein M denotes Mg, Ca, Sr or Ba, n being between 1 and 5, m being between 1 and 10 and x being between 0 and 10. The invention also relates to the zinc anode of the generators used in the invention and the production method thereof. |
