How Can Custom Lithium-ion Battery Pack Life Be Extended?
The world is populated with lithium ion batteries. They are almost everywhere you turn. From smartphones to laptops to electric vehicles and wireless power tools, lithium ion battery has suddenly become a household name today.
While these batteries have remained the most used when it comes to storing energy in mobile devices, there seem to be a great level of confusion regarding how lithium ion battery lifespan can be prolonged.
So to help you understand this, we have decided to dig through several research papers and discoveries that were made by experts. As such, highlighted below are several tips that can help ensure a longer lifespan of your custom lithium ion battery pack. The first on our list is:
Your battery will not last the test of time when you keep exposing it to conditions that are capable of degrading it. Reduce the way you expose your lithium ion battery to such conditions, and it will last for much longer. Here are some of the conditions you should be very aware of.
Avoid extreme temperatures
You are to avoid both extremely low and high temperatures when using your lithium ion battery. High temperatures can facilitate lithium ion battery degradation, leading to serious safety hazards like explosion or fire.
If a smartphone or laptop becomes extremely hot while charging, it is an indication that you should remove the plug from the charging point. Also, avoid subjecting your battery to low temperatures. It has a way of deteriorating the life of the lithium ion battery.
Reduce charging time at 0% or 100%
Ensure your lithium ion battery does not spend too much time charging at 100% or 0%. These extreme percentages bring a lot of stress to the battery. Consider doing a partial charging that will keep the battery at 80%, instead of allowing it fully charge to 100%. If you cannot achieve that, make sure the device is removed from charging the moment it gets to 100%.
LG and Samsung has recommended that their products be put to charging when it gets to 20%. Sony and Nokia meanwhile said that their smartphones are liable to battery damages anytime they are left to charge above 100% for a long time.
In many laptops, the battery management system triggers to battery to stop charging the moment it gets to 100%, and will not resume charging until the battery level drops to 95% or below. Notwithstanding, manufacturers still advocate that you unplug your laptop anytime it becomes fully charged.
Fast chargers are not necessary
All chargers are not the same. Some will charge your lithium ion battery faster than others. One thing users have gotten used to recently – is the habit of using fast chargers to charge their devices. Fast chargers are superb. They can get you back to using that device as soon as possible.
But, studies have indicated that using fast chargers is a way of running down your lithium ion battery. And when a battery begins to discharge too fast, it is unhealthy for the lifespan. Standard charging is the best. You can also take extra measures to stop your device from discharging too quickly. For laptops and smartphones, reducing screen brightness, disabling location services, as well as quitting high-power applications when not in use will help a lot in reducing the rate of battery discharge.
Avoid storage or use of lithium ion batteries within environments that contain high amount of moisture. Also, if you can, ensure the batteries are not punctured, hit, or damaged by any means.
Most manufacturers who are into wireless power tools have also advised against allowing the battery to completely run down before they are recharged. Some equally recommend a least temperature of 37F and a maximum temperature of 104F when charging the battery.
Battery cells are composed of electrodes (anode and cathode), as well as an electrolyte that can react with either electrode. Lithium ion batteries, like every other battery, degrades slowly as you use it. Every part of the battery will be affected in the process. The cathode, anode, electrolyte, current collector, and separator will all be affected.
Battery degradation comes in two basic formats: power fade and capacity fade. Capacity fade has to do with the reduction in the quantity of power the battery can store, whereas power fade is all about the reduction in power produced by the battery.
Prolonging lithium ion battery lifetime reduces the environmental burdens and costs linked with producing new batteries. This includes material consumption, greenhouse gas emission, mining impacts, and the environmental risks of battery disposal.
As the portable electronics and electric vehicles continue to grow, a small extension in battery life will have a huge impact on the environment.
Recoverable & permanent losses
Lithium ion battery loss are of two types. It is ether they are recoverable or permanent. After charging a lithium ion battery to 100%, it is bound to lose 5% of that capacity in the first twenty-four hours. A percentage of about 3% will be lost every month due to self-discharge and when the battery is equipped with protection circuits.
Self-discharges have been attributed to the surrounding temperature of about 20C. That figure will increase when the temperature is higher, as well as when the battery starts to age. Fortunately, charging is all that is required to recover this kind of battery loss (recoverable).
As you can rightly discern, permanent losses cannot be replaced. Once a lithium battery is on that route, it is gone. The best way to avoid a permanent loss is to know what the causes are. Permanent loss can be caused by a number of factors such as the frequency of full discharge/charge cycles, temperature, and battery voltage.
The lifespan of your lithium ion battery is in your hands. If you are careful about all what has been said here and apply them where necessary, it will benefit your battery long-term. Battery capacity losses are inevitable; we can only minimize them.
