Lithium nickel manganese cobalt oxide (NMC811, NEI Corp.) positive Li-ion electrode samples of areal capacity 2.2 mAh cm -2 was secured to a petri dish using Kapton® tape before being fixed to the translation table of a laser micro machining instrument (A Series, Oxford Lasers Ltd.) containing a 352 nm laser with a spot size of ~40 um. The laser was programmed to mill a series of lines at 2 mm s -1 . The resultant electrode was cut to 15 x 20 mm (w x h) with a protrusion of 500 x 250 µm (w x h) from the top of the main electrode body. This area is used to image the electrode with limited FoV techniques and will be referred to as the tab. Additionally an area of 5 mm x 10 mm was milled into the opposite side of the electrode to allow for ultra-sonic welding of an aluminium terminal to the electrode's bare current collector.
