A thin-film battery with a Li/LPO/LCO/SRO/STO structure was fabricated with the epitaxial LCO (104) film. The thin-film batteries delivered steady lithium deintercalation and intercalation of LCO at high voltages ranging up to approximately 4.6 V without severe degradation.
Despite the huge potential of mechanically flexible batteries in healthcare, robotics, transportation and sensing, their development towards real-world applications is stalled due to issues such as capacity decay, limited energy/power density at any given pliability, compromised safety and poor packaging.
The bio-inspired battery demonstrated excellent dynamic capacity stability over 35 electrochemical and 11,000 bending cycles, as shown by the discharge capacity and coulombic efficiency of the cell when in unbent, positive bend and negative bend states (Fig. 7h).
An advantage of thin materials is good interfacial contact with the electrolyte and thus more reaction sites compared to thicker electrodes. Subsequently, thin devices often utilise GPEs, which may be functionalized to achieve good electrochemical performance and high electrode/electrolyte contact despite high viscosity 99.
