Reverse Engineering : Investigation on the Material Trends in Lithium-ion Battery

We obtained lithium-ion battery cells from 3 different commercial electric vehicles manufactured by an automotive company for the reverse engineering investigation. We named the samples “Model A,” “Model B,” and “Model C” here. Model A is the newest and Model C is the oldest vehicle model among the three samples. We disassembled and analyzed each of the cathode sheets, the anode sheets, and the separator sheets using multiple analytical instruments.
