Nano-sized Al-Ni energetic powder material for heat release element of thermoelectric device

Abstract

In this paper, a method of fabrication of an Al-Ni powder energetic material with a 90-100 nm particles is proposed and experimental results of a study of its properties are presented. High values of specific energy and the rate of its release make it possible to use this material as an heat release element in thermoelectric power generation devices. It has been demonstrated experimentally that it is possible to maintain a voltage value higher than 1 V for 45 seconds as a result of combustion of a 3 gram Al-Ni sample that using a simple DC-DC converter will allow charging supercapacitors or accumulators.
