Abstract
A new anode configuration (20) is proposed for a lithium microbattery (10). The anode (20) preferably consists of nanotubes or of nanowires (24) such that the empty space (26) left between the different components (24) provides compensation for the inherent swelling upon discharging the microbattery (10). With the absence of stresses on the electrolyte (18), the lifetime of the battery (10) may be increased.
