Will lithium battery be unavailable if it is stored for a long time?

Introduction

Lithium-ion batteries have become prevalent to power anything from electric vehicles to cellular phones. They are a popular choice for portable electronic gadgets due to their lightweight nature, excellent density of energy, and rechargeability. But many of us can overlook a vital aspect of lithium batteries: the effect of storage for years on their performance.

Like any other product, lithium batteries have an expiration date. Extended periods of inactivity cause them to lose functionality, live shorter lives, and even pose safety risks. We'll delve into the complexities of batteries made of lithium-ion in this blog post, examine the effects of keeping them unused for extended periods, and offer maintenance advice to maintain these power sources operating at their best.

What Do lithium batteries Do?

Let's quickly define a lithium-ion battery before getting into the mechanics of long-term storage. A particular kind of battery pack called a lithium-ion battery relies on the movement of lithium-ion ions through the positive and negative electrodes to store and discharge electrical energy.

One of the main advantages is the elevated energy density of lithium-ion batteries, which allows them to store a substantial amount of energy in small and light packaging. This characteristic has completely changed the world of portable electronics, paving up for a generation of ultra-thin smartphones, computers with long battery lives, and even electric cars.

These batteries do have certain limits, though. One of them is that they have a limited lifespan, which is affected by several variables, including usage patterns and storage conditions.

Store No More than 4 Months

Like athletes, lithium-ion batteries require constant activity to maintain optimal performance. They could look noticeably worse if you keep them on the sidelines for an extended period. Ideally, it would be best to refrain from keeping lithium batteries inactive for long periods. The most important one for lithium-ion batteries is always using them for four months.

How come this is the case? Lithium-ion batteries gradually lose their charge even when unused since they have autonomy over time. It may become challenging to recharge the battery if it discharges. Deep discharge is the term for this event, which might permanently harm the battery.

Consider the following advice to prevent deep discharge during long-term storage:

●Partial Charge: Charge a lithium-ion battery to about 50% of its capacity before storing it. A fully charged battery can degrade more quickly during storage. Hence, it is not recommended.

●Cold Ambient: The battery should be kept in a cold, dry location, ideally between 20°C and 25°C (68°F and 77°F). Lithium-ion batteries can degrade more quickly in extremely hot or cold climates.

Recharge the Battery in Time

It's important to take the proper precautions while putting a lithium-ion battery back into operation if you ever find yourself in a position where it has been stored for a long time without use. Failure to do so may cause performances to suffer and risk your safety.

Here's how to precisely revive a lithium-ion battery that has been put away:

1.Check for Damage: Visually examine the battery for any indications of physical damage, such as edema, leakage, or odd scents, before recharging it. Avoid recharging the battery if you observe any of these problems since it can be risky. 

2.Partial Recharging: Recharging only a portion of the battery's capacity should be done if the battery is in good shape. Only charge it partially all at once since this will strain the battery and cause overheating.

3.Monitor Temperature: Keep an eye on the battery's temperature while it is charging. Disconnect it from the charging as soon as it gets too hot. A battery that is deteriorating or damaged may exhibit elevated temperatures.

4.Use Battery: Use the battery in your smartphone as you normally would after it has been partially charged. By doing this, you can recycle the battery and stop it from degrading further.

Electronic Components Consume Electricity

Lithium-ion batteries continue to lose energy even when not in use because of the power demands of the device's electrical components, which is another crucial factor to consider. The phenomenon is referred to as "parasitic load."

A tiny amount of power is used from the battery by electronic parts like sensors, indication lights, and even the battery management device. In the long run, this power drain causes the battery to deplete to a dangerously low level and undergo deep depletion.

Use the following advice to lessen the consequences of parasitic load:

1.Power Off: Turn off a lithium-ion battery-powered item fully before storing it for an extended period. Turning off all of the electronics will reduce the battery's drain.

2.Withdraw the Battery: It may occasionally be easy, depending on the device. It is ensured that no energy is consumed when it is not in use by doing this.

3.Check Battery Voltage: Occasionally check the battery's voltage with a reliable multimeter. If you notice a significant voltage drop over time, think about charging the battery to prevent a deep drain. 

Monitoring the battery's voltage may prevent problems before they arise, keeping your lithium-ion batteries in top shape for lengthy storage periods. These easy-to-follow tips can help your batteries last longer and perform better, avoiding unpleasant surprises when powering your devices.

Final Thoughts

Although lithium-ion batteries have completely altered how we recharge mobile devices, they are prone to deterioration and stagnation. These batteries can perform worse and pose safety risks if kept in storage for a long time. If you want to prolong the lifespan and efficiency of your lithium-ion batteries, keep the following important considerations in mind:

●With a complete recharge, the lithium-ion pack should last four months.

●Batteries ought to be maintained in a dry, cool spot out of the way.

●Partially recharge the power source that has been stowed while monitoring the temperature.

●By being aware of it, take actions to lessen the parasitic load, such as turning off devices or removing batteries.

You can improve the functioning and lifespan of your lithium-ion batteries by following these suggestions, so will also guarantee that they are going to securely and dependably power everything you love for many years to come.
