Abstract:
To overcome the layer stacking effect in TiVC films, a laser writing technique was applied. With optimized laser power, an interlayer expansion of 23 times was achieved without compromising the structural integrity. This structural modification effectively facilitates ion transport while preserving the intrinsic high capacity of TiVC. As a result, the electrode retained 42.7% of its capacitance at an ultrahigh scan rate of 1000 mV s-1, demonstrating an exceptional combination of high capacity and outstanding rate performance.

Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
