How to Charge Lithium-ion Battery- Complete Detail
Lithium-ion batteries are chargeable batteries that are not widely used in all the power sectors, like mobile phones, laptops, vehicles, and many other fields.
The features that make lithium-ion batteries better than other batteries are their life span, charging cycle; they can last for a long time without charging, being lightweight and affordable, and many other factors that distinguish lithium-ion batteries from all the other types of batteries.
However, the question which makes the people confused is how to charge Lithium-Ion batteries? Down in this post we provided a full detail on this.
Many people using lithium-ion batteries don’t know how to charge them, as they don’t have sufficient knowledge about the batteries and the charging procedure, so they don’t need to worry. Here we will describe how to charge lithium-ion batteries that can be used for a long time.
Why to Charge Lithium Ion Batteries?
You are thinking about why you need to charge the lithium-ion batteries, as you are not using these batteries directly, but keep in your mind that laptops, mobile devices, and other gadgets that are powered by lithium-ion batteries are also the things that you need to know how to charge them.
So, properly charging all these gadgets means using your devices for a long time after charging just once a day. The charging process of a lithium-ion battery is straightforward, as it can only deal with the electric device that is powered lithium-ion battery, so we discuss how to charge the device of lithium-ion battery.

Charging Lithium-Ion Batteries Steps:
Here are the following steps that you can adopt to charge the lithium-ion battery or the device that is powered by the lithium battery.
Tips for Charging the Lithium Ion batteries
No doubt those lithium-ion batteries are becoming more popular; now, most of the big companies are using lithium-ion batteries in their products, as the lithium-ion batteries can be shaped in different sizes.
But it depends on how you use a device that is powered by a lithium-ion battery, but there are many tricks that you can follow to make your lithium-ion batteries more efficient; here are a few tips.
Understand Battery Language
The first thing you must remember is the battery language, which means understanding the battery charging, discharging, and the chemical reaction that is occurring inside the battery.
We know that lithium-ion batteries consist of two electrodes, one has a positive charge, and the other one has a negative charge. The electrons move in the battery when we charge or discharge the battery, changing the ions from one electrode to another.
When using the devices, the electrons move from anode to cathode outside the battery, but when you are charging your battery, the electrons move in the opposite direction. The charging and discharging is a cycle, and the number of cycles your battery can perform depends on its manufacturing, the components, and mainly how you use your lithium-ion battery.
The unit that is used to measure the rechargeable battery capacity Ah, as we usually discuss that this battery is 4000 mAh. On the other hand, A Lithium-Ion Battery charging and discharging rate are called the C rate, which is also called the function of the C rate.
The C rate means how much time you will charge or discharge the battery like 2C charge-discharge takes 30 minutes.
CCCV Charging process
Charging a lithium-ion battery is not an easy process; you have the select the charger according to your battery; otherwise, a wrong charger can damage the health of your battery. Many people use any charger, claiming that the battery can last for more than one hour after some time. So that’s why you have only to use the charge that you will get with the lithium-ion battery or with your device.
The CCCV means that Constant Current is followed by the Constant Voltage, as the capacity of the charging battery is dependent directly on the voltage, so in case of decreasing, the capacity will also decrease.
So you have to check out the ideal voltage for charging your battery and increasing the charging capacity of the lithium-ion battery. Now there are also floating modes in which we charge the batteries, like the floating solar system.
But many people also oppose the floating mode because they think that this can damage the battery health, and somehow this is true.
Design BMS Carefully
The Lithium battery management system plays a vital role in lithium-ion batteries, and the BMS has two main features: thermal management and electrical management. The thermal management prevents the lithium-ion battery from overheating.
We know that the lithium-ion battery is made from various connected cells and the BMS, so the manufacturers connect all these elements by balancing every wire, as a sound balancing system can increase the battery performance and its Lifespan.
Lower Charger Rate
The professionals recommend always charging the batteries at a lower speed because the lithium ions intercalate smoothly without damaging the electrodes. On the other hand, if you increase the charging speed, the ion will not penetrate the electrodes properly, which can cause battery health damage.
The fast charging rate is also available for the batteries used in electric bikes and vehicles, but their battery life span is shorter. Also Check Best Lithium Battery for Bike
This also depends on how much time it takes for your device to recharge, so you have to check the right tradeoff between the charging time and speed of the lithium-ion battery. The ideal charging rate that is considered best for the electrodes is C/50, but not all applications can afford the charging time for more than 50 hours.
Lithium-ion Charge Discharge chemistry
The lithium-ion battery provides current to the device when it is discharging. Still, inside the cell, the chemical reaction occurs in which the anode releases the lithium ions and passes to the cathode. These ions release the electrons, which flow in the opposite direction of the lithium ions.
After that, both the electrons and ions combine at the cathode; in this process, the chemical energy is the release that is stored in the cell in the form of electrical energy.
The above process happens when the battery is discharging. When you are using the device without connecting it to electricity, the same process happens when the battery is charging; the only difference is that it happens in the opposite direction.
The lithium ions move towards the anode from the cathode, and the electrons also move in the opposite direction of the lithium ions. You have to keep in your mind that the charging process is not 100% efficient because of some energy loss as heat, and the battery efficiency level is only 95%.
