What are the advantages of lithium AA batteries?
Lithium-ion batteries have built a reputation for itself that no product can overcome, at least for the time being. Lithium-ion batteries have proven to be the best solution for a rechargeable source of energy. Not only that, but nowadays energy can be stored from renewable resources (sun and wind) directly to lithium-ion batteries.
Scientists believe that there is no need to find a replacement for lithium-ion batteries. Instead, all of the current research work is to upgrade those batteries. Since the first lithium battery that was designed in 1970 until this moment, all that was done in the field was upgrading and enhancing the same battery "Lithium-ion battery"
The current researches focus on removing the flammable liquid from inside the lithium-ion batteries. The liquid that can cause those batteries to catch fire. The call the new upgrade a Solid-state battery.
It is also worth mentioning that the Lithium-ion batteries now are the most economical solution for portable energy sources. Their manufacturing prices have become very affordable, that they are the number one choice for every single mobile phone, laptop, and even electric cars manufacturers.
Another reason that makes the Lithium-ion batteries irreplaceable -at least for now- is their size. Storing Lithium-ion batteries in bulk is a simple task. They are compact, small, flexible and versatile. They can be stored easily and hassle-free. Not only that, but their shelf life is phenomenal. One battery can be stored for up to ten years.
Researches now are also focusing on how to integrate Lithium-ion in all energy storage aspects. However, the problem they are facing is the discharge rate, which is relatively small. The challenge now is to produce a lithium-ion battery with a very slow discharging system that can last for more than one day. Moreover, researches are also concerned by the size of these batteries. They want to make a small battery with a large capacity. As mentioned before, electric cars' batteries before were around two tones, nowadays they are only 300 kg. If they could make it even less, it would be a huge step in the right direction.
In addition, integrating lithium-ion batteries in more applications will eventually save the planet. That is because -as previously mentioned- you now can store energy in the battery coming from renewable resources. Thus, reducing the need for fossil fuels. If we succeeded in reducing the need for fossil fuels even by 5% annually. Then in less than a century from now our planet would be saved from the harmful emissions that come from using fossil fuels.
Conventional Lithium-ion batteries operate at a 3.7V per cell. However, AA lithium-ion batteries have circuitry inside their cells so that the voltage is reduced to 1.5 volts instead of 3 volts. Lithium-ion AA batteries have a capacity that matches the highest NiMH batteries capacity, and they are a lot lighter than them. However, they are more expensive than NiMH ones.
There are also other Li-ion AA batteries that are designed for heavy-duty purposes. Like the 18650 and the CR123A.
The 18650 batteries are Lithium-ion rechargeable batteries. The scientific name for them is 18650 cells. They have a 3.7V voltage and have capacities between 1800 mAh and 3500 mAh. The average charge time for the 18650 battery is approximately four hours. The 18650 batteries are larger than the AA batteries. They are used widely in the robotics world.
Most 18650 batteries last between 300 and 500 charge cycles. However, the lifespan of these batteries can be extended beyond those numbers if you charge the batteries regularly before they completely discharge. Since the 18650 battery is a LiPo battery, it will degrade over time, which unfortunately is an irreversible process. With proper usage, you can get over a year or two of life from your battery.
Moreover, AA Lithium batteries have many advantages over their counterparts:
They are designed to last longer, for up to four times more than their counterparts.
They are perfect for heavy-duty devices
Lithium batteries can withstand extremely low temperatures.
They are much lighter.
All of the above makes the AA lithium batteries a perfect choice for most applications.
How much are lithium AA batteries?
Prices of AA Lithium batteries vary from one company to another and depend on more than one factor. From shelf life to heavy usage, there are numerous variables that contribute directly to their prices.
However, in 2019 market AA Lithium batteries varies from $2.33 per count to $9.99 per count. Moreover, they are available easily in most retail stores and on Amazon.
