Part of the MEMS Reference Shelf book series (MEMSRS, volume 6)


In this chapter, the application of high power density (1–2 W/cc) and high energy density (100–200MJ/cc) 147Pm fuel in 1–20mW/cc, 5 year lifetime microbatteries is explored. The resulting >220 W-h/cc microbatteries could potentially replace the currently employed 1–10 W-h/cc electrochemical batteries [18] and enable longer lifetime autonomous microsystems
