- Description
- The rapid growth of smart technology has accelerated the need for compact and durable microbatteries. Fabrication of thin-film microbatteries is effective to address the requirements of the evolving technology. In the present work, pristine, optically transparent, nanoporous LiFePO4 (LFP)is synthesized via RF magnetron sputtering. The effect of nanoporosity on the electrochemical properties and charge storage mechanisms of LFP is explored. The galvanostatic studies revealed an initial discharge capacity of 32 Ah cm2?m1 and stabilised to 17.5 Ah cm2?m1 after 100 cycles. The capacity fading can be attributed to the increased formation of SEI caused by the enhanced interaction between the cathode and electrolyte due to the nanoporosity. The films demonstrate good rate capability and reversibility. Optical studies reveal a bandgap of 3.74eV, highlighting the potential for usage in optically transparent microbatteries. This work provides key insights into the intrinsic electrochemical behaviour of pristine nanoporous LFP thin films, creating a pathway for its implementation in microbatteries.
