Do Lithium-ion Batteries Lose Charge When They Are Not in Use?

A lithium-ion (Li-ion) battery is a high-tech battery that employs lithium ions as an essential component of its electrochemistry. Lithium atoms in the anode are ionized and separated from their electrons during a discharge cycle. The lithium ions travel from the anode through the electrolyte to the cathode, where they recombine with their electrons and electrically neutralize.

If you have had a smart phone for more than a year or two, you must have noticed that the lithium-ion batteries degrade over time and refuse to hold a charge like they used to. The following article is mainly divided into three topics, so take a look at them to know everything about lithium batteries.

Do Lithium-ion Batteries Go Bad If Not Used?

This is a frequently asked question around the world. You usually buy lithium batteries with the expectation that they will last for a specified amount of time. Lithium batteries have an estimated life of two to three years with 300 to 500 charge cycles. However, this is not always the case, and lithium batteries can go bad after a short period of time. However, there is no possible way of knowing what caused the batteries to die suddenly.

As a result, you must pay attention to what is being discussed here. This will save you money and the trouble that death batteries cause. Take note of every detail, and rest assured that you will be able to enjoy the benefits of a well-functioning lithium battery.

What Causes lithium battery to Go Bad?

Some of the conditions that we subject lithium batteries to cause them to fail. After a few years of use, the batteries die. As a result, we will look at some of the causes of lithium battery death. They are as follows:

1) The Effect of Solid Electrolyte Interface

During the charging process, lithium gravitates to the negative electrode, changing the voltage potential of the battery. The removal of the lithium during discharging does not completely reset the battery. A stable electrolyte interface is formed on the surface of the anode by a mesh of lithium atoms (SEI).

2) Temperature Affect

Heat is the most common cause of lithium battery failure. Lithium batteries can be destroyed by extreme heat or cold. The reduced temperature has an effect on the transformation of active chemicals within the cell. Also, this lowers the cell's current holding capacity for both charging and discharging.

Low temperatures also slow the rate of chemical reaction, slowing the insertion of lithium ions into the intercalation space. As a result, power is reduced, and the anode's lithium plating suffers from capacity loss.

High temperatures cause a new set of problems that can result in total battery damage. The reaction rate is increased, resulting in higher currents and, as a result, higher I2R heat dissipation and, as a result, even higher temperatures.

3) Age

Batteries deteriorate as they age. As a result, the batteries die as a result of the numerous recharge cycles. As time passes, the plates are covered with mesh-like chemicals. The lithium battery will then sustain permanent damage as a result of this.

4) Fatigue Due To Mechanical Action

When lithium cells are charged or discharged, their negative electrodes expand and contract. This is due to the effect of lithium I intercalation in and out of the crystal electrode structure.

Why Do Batteries Lose Charge When Not In Use?

For standard, grocery-store single-use batteries, the answer is simple. As the chemical electrolyte completely transforms, the battery eventually loses its ability to generate new ions that can run the gauntlet of the circuit it creates with your electronic device. There is no chemical electrolyte, no ions, no electrons, and no battery power. The term "Rock Content" refers to the total amount of chemical electrolyte that is used.

Your smartphones use a lithium polymer battery, which is more prone to power shortage after the automatic power off and on cycle. The Smartphone runs out of control, and the possibility of it not booting up arises. The battery has most likely entered sleep mode. The main board battery of the Smartphone is also dead, and the charging programme code cannot be started at boot; remove the battery and insert it with the imported mobile phone charger for about 30 minutes before placing it on the mobile phone to test it. If it can be switched on, recharge it with a line charger. Paying no attention to the problem of mobile phones, even if the battery is dead, you can switch it on and off

How to Tell If A lithium-ion battery Is Bad?

They frequently exhibit swelling; be careful not to come into contact with any leakage and dispose of in accordance with local regulations. Furthermore, they do not hold a charge well and become hot while charging.

The most obvious sign that a Li-Ion cell is nearing its end of life is that it no longer holds a charge well, performs poorly, and becomes noticeably warmer when charging. Following are some points related to the topic. 

See if it inflates or overheats.

If it won't chare or won't hold a charge anymore or shows voltage bellow specified with a timer

Now is the time to check the voltage. It could be dangerous if it is above or below the normal limits. However, if there are protective circuits, a completely dead battery may simply be sleeping. You can sometimes bring them back to life by connecting them to a known good battery for a minute or three. However, the damage may already be done. Some say don't even try to resurrect a dead lion; instead, throw it away.

Charge the battery using a reputable charger. Examine the voltage and temperature. If it becomes too hot, discard it. If the voltage falls below the normal full voltage, discard it.

Check the voltage to see if it is within the specification for a fully charged battery.

Place the now-fully charged batteries in a cool, preferably fireproof, location.

Wait about two weeks.

Examine the voltage.

Any battery with a significant voltage drop should be discarded.

Conclusion

No matter what type of battery it is or what material it is made of, it will drain the charge even when not in use. Similarly, when not in use, Lithium-Ion batteries will drain. If you charge the battery when it is completely discharged, you will reduce its capacity. So, whenever you trust it, make sure there is still some charge in it! It should not be entirely drained. The above article has explained how the lithium batteries turn in bad condition if not taken; this article will also help you know when your lithium batteries state is getting worse.
