The invention deals with a sensor for sensing electrolyte creepage in a battery, a circuit comprising such sensor, and a battery connected to such circuit, with an application to an electrical circuit comprising the sensor and connecting a monitoring equipment to a to battery. The sensor element is adapted for being connected within an electrical circuitconnected to a battery, said battery comprising one or more electrochemical cells containing an electrolyte, wherein the sensor element comprises a electrical conductor element whose at least one electrical property varies when in contact with the electrolyte, such as to allow, when the sensor element is connected in a circuit, detection of an electrolyte creepage from a an electrochemical element of a batteryconnected to the circuitby measurement of the variation of the one electrical property of the conductor element.

The hydration of cadmium oxide in the presence of nickel acetate gives the possibility of obtaining a compound of general formula CdNi(OH)(CHCO)with 0&#x3c;x&#x2266;0.05 and 0&#x3c;y&#x2266;0.10. This compound may be advantageously, used as an electrochemically active material of an anode of the envelope type of a nickel cadmium generator. This anode does not contain any sulfates responsible for the formation of short-circuits. Further, this anode has a high electrochemical yield. A method for preparing this compound and the anode is described.
