From: Closed Loop Recycling of Electric Vehicle Batteries to Enable Ultra-high Quality Cathode Powder
SEM images of precursors that collected at different range of time and the final cathode (bottom right). For example, Day 1 shows SEM images of Day 1 precursor with a magnification of 200 (scale bar: 100 μm). The insert for the Day 1 precursor shows the SEM of the same material with a magnification of 1,500 (scale bar: 10 μm), etc.
