A thermal battery(30) is housed in a chamber that utilizes micro-electromechanical systems (MEMS)-based technology to offer superior chemical stability and advantageous mechanical and thermal properties. The thermal battery of the present invention is activated by heat, for example heat generated by a pyrotechnic charge(32), for example thermite, for immediate and thorough activation of the electrolyte. The anode(36), cathode(38) and electrolyte(40) of the battery are formed of pellets having a curved interface for increased current density. The electrolyte preferably comprises a three-component eutectic salt mixture. In this manner, the thermal battery of the present invention is well suited for applications that require highly integrated thermal batteries that are relatively small in physical size, yet are capable of reliable performance over a wide range of operating conditions. |
