To address this issue, we present the current limit estimate (CLE), which is determined using a robust electrochemical-thermal reduced order model, as a function of the pulse duration, depth of discharge, pre-set voltage cut-off and importantly the temperature.
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.
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.
However, at high specific currents, the overvoltage that drives the Li-ion insertion reaction increases due to limitations of the interfacial kinetics, charge and mass transport. Consequently, the electrode potential, falls below the Li/Li + redox potential and deposition of metallic lithium becomes possible.
For high rate charging at the cathode, there is a risk of forming a higher resistance phase around the predominantly hexagonal or rhombohedral phase particles . A high rate charge pulse can lower the surface lithium concentration to the point at which irreversible phase change can occur.
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.
bre A) was used between the H1609 and the lithium metal. This minimised the risk of dendrite formation during the tests. The formation, limits of 0 – 5 V and ± 150 mA. The high rate current pulse tests used a Maccor 4000 unit, with limits of - 2 V to + 8 V, and ± 5 A. For the 0.005 –1.5 V. The cathodes used 2.5–4.2 V, with a CC-CV charge pro-
