Abstract: A safety battery apparatus comprising a battery housing within which is located one or more rechargeable electrochemical cells, and a heat safety apparatus associated with the battery housing, wherein the heat safety apparatus includes a heat detection apparatus and an electrical switch that forms part of an electrical circuit to which the electrochemical cell(s) are connected and/or forms part of an alarm circuit; the heat detection apparatus comprises a frangible bulb filled with a liquid or gas that is configured to shatter or break at a pre-determined temperature as a result of thermal expansion of the liquid or gas within the bulb, and a biasing element; the heat detection apparatus is operatively coupled to the electrical switch; the switch has an isolation configuration in which the switch isolates the electrical circuit from the electrochemical cells and/or activates the alarm circuit if a pre-determined threshold temperature within the battery housing is exceeded; the biasing element exerts a biasing

Abstract: An electrical component including a polymeric body which (i) defines at least one electrical connection; or (ii) is configured for attachment to an electrical cable or wire; or (iii) is configured for attachment to an electrical apparatus, wherein the polymeric body or a portion thereof includes a thermochromic composition which has a first colour condition below a first threshold temperature and a second colour condition if the composition is heated above the first threshold temperature, and wherein the thermochromic composition maintains the second colour condition until it is cooled below a second threshold temperature.
