Millimeter scale thin film batteries for integrated high energy density storage

摘要

TFBs of 95μm total thickness show a discharge capacity of 25μAh and maintain 60% of this value at 0.25mA. Upon cycling, TFBs exhibit excellent capacity retention, with an average loss of 0.05% per cycle. Results at 37°C present similar performance, thus highlighting the great potential of these TFBs as integrated energy storage solution in particular for medical implantable, injectable and wearable solutions.
