"is that Lithium ions should not be transferred between two battery terminals at a rate exceeding two moles per minute."
Seems to a be a missing parameter here. Moles per minute per unit of area? For example: per square cm or square meter.... In any case, it seems to be a large number of charges transferred regardless of the areal dimensions of the transfer surface. Given that 1 Coulomb is an Ampere second, and that there are ~96 thousand coulombs per mole: Hence at this suggested "limit" we are indeed at huge, and unlikely to be realistic, implied power densities.
