However, lithium-ion batteries defy this conventional wisdom. According to data from the U.S. Department of Energy, lithium-ion batteries can deliver an energy density of around 150-200 Wh/kg, while weighing significantly less than nickel-cadmium or lead-acid batteries offering similar capacity. Take electric vehicles as an example. The Tesla

This excellent video from BASF covers what happens inside lithium ion batteries when they are charging and discharging. Although its focus is on batteries for electric vehicles the basic principles remain the same for all lithium ion units.
Rechargeable lithium-ion battery with charger. The circuit diagram below represents a simple Li-ion battery charger circuit. However, the above circuit lacks a temperature regulation feature. Hence, when charging, use a relatively low input current. This lithium-ion battery charger is a simplistic circuit that requires the following components:
Lithium-ion batteries have a terminal voltage of 3-4.2 volts and can be wired in series or parallel to satisfy the power and energy demands of high-power applications. Battery models are important because they predict battery performance in a system, designing the battery pack and also help anticipate the efficiency of a system [ 1, 2 ].

Besides, it is compatible with USB supplies and wall adapters. For best results in charging a 3.7 V Lithium-ion battery, apply a constant current of approximately 20 to 70 % of its capacity. You should do this until it reaches 4.2 V. Afterwards, charge the battery at a constant voltage until there is a 10% drop in the initial charge rate.
Lithium-ion batteries’ popularity is rising owing to their significant advantages over lead-acid batteries. However, a Li-ion charger circuit is different from that of the latter. Next, let’s discuss them. A Li-Ion Battery You can charge a Li-Ion battery at a rate of 1C, equivalent to the battery’s Ah rating.
Thus, connecting a discharged 3.7 V Lithium Ion Battery will prompt the IC’s pin 2 to detect the low voltage level and set it high. It initiates the charging process. When the battery archives its threshold full charge capacity, Pin 6 will change the output to low. Thus, this will limit further charging.
Primarily, the IC’s pins 2 and 6 are responsible for controlling the lower and upper voltage limits, respectively. Thus, connecting a discharged 3.7 V Lithium Ion Battery will prompt the IC’s pin 2 to detect the low voltage level and set it high. It initiates the charging process.
