A miniature 10 mAh, 3.75 V Li-ion battery (button cell) has been developed for external medical application. The miniature cells (0.2 cm3) show excellent performance in terms of cycle life, energy and power. Life tests have exceeded 2700 cycles at 60% DOD and discharge rates of 1-3 mA. Full discharge tests (100% DOD) have shown very good performance with more than 90% of the capacity delivered at the C-rate. Pulse discharge tests indicated excellent pulse capabilities of up to 100 mA over low-level background currents of 10-100 μA. © 2001 Elsevier Science B.V.
