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.
In fact, the internal charging mechanism of a lithium-ion battery is closely tied to the chemical reactions of the battery. Consequently, the chemical reaction mechanisms, such as internal potential, the polarization of the battery, and the alteration of lithium-ion concentration, have a significant role in the charging process.
The battery charging voltage of this chip is given as 4.2 V. Datasheet I know that 3.7 V Li-Ion batteries charge smoothly up to 4.2 V. But what I'm wondering is, can the Li-Ion battery stay at 4.2 V voltage for a long time? Will it damage the battery?
The charging voltage limit for a Sony Li+ battery is 4.2V. If the voltage between terminals is allowed to reach 4.45V, the battery life is compromised.
This is the maximum cell charging voltage, according to the data sheets. The LFP cathode in the M1A cell reached the 3.6 V cell charge limit at around 10 C. After the initial resistive increase, the electrodes then switched to a diffusion limited process, as indicated by the linearity of the voltage vs. t 0.5 plots.
For a Li+ battery, CCCV (constant current, constant voltage) is the universally accepted charging method. With the exception of the voltage source/resistor method used exclusively for very small capacity (a few mAh) Li+ batteries.
