There was an immediate voltage change when the high rate pulses were applied. The maximum current that could be applied to the cathodes, at the rated charging voltage limit for the cells, was around 10 C. For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode.
(The metal-lithium battery uses lithium as anode; Li-ion uses graphite as anode and active materials in the cathode.) Lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest specific energy per weight.
Most Li-ion batteries share a similar design consisting of a metal oxide positive electrode (cathode) that is coated onto an aluminum current collector, a negative electrode (anode) made from carbon/graphite coated on a copper current collector, a separator and electrolyte made of lithium salt in an organic solvent.
For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode. This introduces the possibility of lithium plating. Another issue is that the diffusion limited process could not be sustained through many of the high rate, 10 s pulses.
1. Introduction Lithium-ion batteries (LIBs) dominate as the energy storage devices of choice in applications ranging from mobile electronics to electric vehicles. The operational characteristics of LIBs are temperature dependent, and frequently find themselves exposed to drastically varying temperatures while in operation.
On discharge, the anode undergoes oxidation, or loss of electrons, and the cathode sees a reduction, or a gain of electrons. Charge reverses the movement. Li ion batteries come in many varieties but all have one thing in common – the “lithium-ion” catchword.

If a battery is specified to deliver 9 amps, and you limit current to nine amps, the battery will likely achieve lifetime performance reasonably similar to what is specified in the datahseet. Going beyond the rated current may not cause immediate failure, but is likely to adversely affect device lifetime. Trying to draw e.g. 10 amps from a 9 ...
