A review of current collectors for lithium-ion batteries
A typical LIB is composed of a cathode, an anode, a separator, electrolyte and two current collectors, as shown in Fig. 1 a. Commonly used cathodes include LiCoO 2 (LCO), LiMn 2 O 4 (LMO), LiFePO 4 (LFP), and LiNiMnCoO 2 (NMC) and the anode mainly used is graphite [7, 8], which more recently contains additional active components such as SiO x to

Pylontech Charge Current Limit
Second, the charge current limit is dynamic, which means that somewhere between 95 and 100% SOC the battery will reduce the charge current limit. This is normal. If you enable DVCC, disable SVS and STS, and enable current limit then you should not have to see a reduction from your MPPT. In other words, you can have 60A coming from the MPPT and

How to measure charging current for TP4056 module?
You only expect to see 1A (assuming R PROG =1.2kΩ) under specific circumstances e.g. battery voltage >2.9V (V TRIKL), and that is after a short period of rising charge current, up to a maximum of 1A - see the TP4056 datasheet. If a battery is not attached or <2.9V then you would only measure a maximum of the trickle charge current, as you

When it still has charge it can be up to 4.2 V. I use an average of 4V. The 12 V, 1.5 A from the charger will be (efficiently) converted by a switching charging circuit to 4 V and 4.5 A. So although 1.5 A (at 12V) is taken from the power adapter, the battery is charged with 4.5 A (at 4 V) ! So charging 20 Ah at that current will take 5 hours.
