| Abstract Scope |
With a growing population and increasing energy consumption, there is a pressing need for clean energy conversion and storage devices to build a sustainable society. Protonic ceramic electrochemical cells (PCECs) are considered one of the most promising candidates due to their excellent ionic conductivity at intermediate temperatures (300-600°C). However, problems such as high contact resistance caused by electrolyte surface defects and poor interfacial bonding have hindered their development. Herein, we have developed a digitally controlled laser ablation method with high controllability, flexibility, and scalability to engineer the electrolyte surface with desired roughness and patterns to improve the interface chemistry and bonding between the cathode and electrolyte. The PCECs, after undergoing the laser engineering process, demonstrate decreased contact resistance and a multiple-fold increase in peak power density compared to that of the pristine ones. |
