  • Methods of preparing a safety battery
    Patent number: 10826050
    Abstract: The present invention relates, in part, to methods of preparing a safety battery. Methods can include dispensing a safety ink formulation between the two poles of a battery. Upon exposure to moisture, the formulation provides an electrical connection between two poles, thus minimizing electrical discharge and/or reducing the formation of electrochemically generated ions at the pole(s).
