Researchers at WMG at the University of Warwick (UK) have developed a method to assess the maximum current for commercial 18650 Li-ion batteries, using novel instrumentation methods enabling in operando measurements. In an open-access paper in the journal Electrochimica Acta , they reported that the maximum charging current that could be safely applied to the evaluated high-energy cells is 6.7 times higher than the manufacturer-stated maximum.
