Abstract: A peel off assembly for exposing a safety feature comprising an aversive agent for a battery includes a first adhesive layer adhered to a base layer. Optionally, a layer comprising a colorant is disposed over and coupled to the first adhesive layer. A layer comprising a water-soluble material and an aversive agent is disposed over and coupled to the first adhesive layer. A second adhesive layer is disposed over and coupled to the layer comprising a water-soluble material. A kill strip layer is disposed between the second adhesive layer and the base layer. Optionally, a label is disposed over and coupled to the second adhesive layer. The second adhesive layer is adapted and arranged to release from the layer comprising the water-soluble material, when a peel force is applied such that the second adhesive layer and the kill strip layer are removable from the layer comprising a water-soluble material when the peel force is applied to the second adhesive layer.

Abstract: A reusable battery indicator includes a voltage sensor, a communication circuit communicatively connected to the voltage sensor, an antenna operatively coupled to the communication circuit, and a connector. The connector is electrically connected to the voltage sensor, and the connector is adapted to be removably connected to a battery, thereby providing an electrical connection between the voltage sensor and the battery. An electrical circuit is completed between the voltage sensor and the battery and the voltage sensor. The connection mechanism includes part of an electrical lock and key assembly.

Abstract: The invention is directed towards an electrochemically active cathode material for a battery. The electrochemically active cathode material includes a non-stoichiometric beta-delithiated layered nickel oxide. The non-stoichiometric beta-delithiated layered nickel oxide has a chemical formula. The chemical formula is LixAyNi1+a-zMzO2•nH2O where x is from about 0.02 to about 0.20; y is from about 0.03 to about 0.20; a is from about 0.02 to about 0.2; z is from about 0 to about 0.2; and n is from about 0 to about 1. Within the chemical formula, A is an alkali metal. The alkali metal includes potassium, rubidium, cesium, and any combination thereof. Within the chemical formula, M comprises an alkaline earth metal, a transition metal, a non-transition metal, and any combination thereof.

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).
