AI Article Synopsis
- LMO thin films are created on Si substrates with a platinum current collector using a special method called multi-layer pulsed-laser-deposition.
- These films demonstrate impressive electrochemical cycling performance, achieving a high reversible capacity of 2.6 μAh cm at current densities up to 1880 μA cm.
- The cycling stability is exceptional, maintaining 99.996% capacity retention over 3500 cycles, indicating a significant contribution from nondiffusion-controlled, pseudocapacitive-like storage mechanisms in the LMO electrode.
Article Abstract
LiMnO (LMO) thin films are deposited on Si-based substrates with Pt current collector via multi-layer pulsed-laser-deposition technique. The LMO thin films feature unique kinetics that yield outstanding electrochemical cycling performance in an aqueous environment. At extremely high current densities of up to 1880 μA cm (≈ 348 C), a reversible capacity of 2.6 μAh cm is reached. Furthermore, the electrochemical cycling remains very stable for over 3500 cycles with a remarkable capacity retention of 99.996% per cycle. We provide evidence of significant nondiffusion-controlled, pseudocapacitive-like storage contribution of the LMO electrode.
