Device for indicating the fully charged state of a battery
First Claim
1. A device for indicating the fully charged state of a storage battery, especially a lead-acid storage battery, by determining the temperature of a recombination catalyst, comprising a temperature-sensitive electronic component whose surface is provided at least partially with catalyst material, and is adapted for exposure to the battery gases, wherein the catalyst material is covered with an antimony-adsorbing layer.

Abstract
The temperature rise associated with the catalytic recombination of battery gases at the end of the charging process is converted into an electrical signal suitable for checking and controlling charging, in a temperature-sensitive component such as a commercially available NTC or PTC resistor coated with a PTFE-bound palladium-activated carbon mixture. An additional activated carbon layer protects the catalyst from poisoning by the stibine present in the battery gases.
