During the 1970s John Goodenough and Stanley Whittingham developed a new technology of using lithium-ion for power supply. These batteries are designed so that lithium ions move from anode to cathode through the electrolyte. It is a salt of lithium. The high energy density and low self-discharging of the batteries make them perfect for electronic appliances. These batteries are used in electric vehicles. Their uses are increasing in military and aerospace operations. Generally, the negative electrode is made up of carbon and metal oxide is used to make anode. The electrolyte is a mixture of ethylene carbonate and diethyl carbonate that contains lithium complex-ions. The design of the battery depends upon usage.

The voltage, energy density, and safety of these batteries can be changed according to the use. Lithium in its pure form is very reactive. So the electrolyte should be non-aqueous. Lithium is used n batteries due to its high energy providing quality and vigorous reactivity. Lithium-ion batteries are expensive as compared to a NiCad battery. These batteries can operate over a wide range of temperatures. The lithium-ion cells can be small-cylindrical or large-cylindrical.?


What is a rechargeable battery?

A rechargeable battery is known as a storage battery. It is a type of electrical battery. The reverse electrochemical reaction is used to accumulate energy in the battery. These batteries come in many shapes and sizes. These batteries are also known as accumulators. These batteries are good for the environment as they do not harm it. They can be used many times by charging it at a low cost.

What is the best lithium-ion rechargeable AA battery?

The disposable alkaline batteries are replaced by the AA batteries. This is due to the improvement made in the recharging process. The best lithium-ion AA battery provides 1.5 volts. They have a long life cycle. The lithium-ion batteries maintain more even voltages than any other cell. These batteries are used in high-performance flashlights and cameras. The high energy density provided by these batteries is about 3.7 volts. The AA batteries are the most popular batteries that are rechargeable. This is because the size of these batteries is good. Battery capacities are measured in mAh. AA batteries have a value of 2000 mAh.?

Characteristic of the best lithium-ion rechargeable AA battery


The energy density by weight and by volume can be measured for the best batteries. The gravimetric density of lithium-ion batteries is 90 W-R/KG. The volumetric densities of these batteries should be 210 W-R/L. this means that lithium-ion can be made much lighter than other batteries.


The lithium-ion provides 3.6 volts. These batteries are much better than NiCad or Ni-MH batteries that provide only 1.25 volts. The efficiency of the power of lithium-ion batteries can be improved by using switching converters.


The lithium-ion batteries are the best among all rechargeable. They have a small self-discharging percentage. It is very much clear that a battery having 30% self-discharging will lose at least 20% in the first few days of the month. The best lithium-ion battery has 5-10% of self-discharging per month.

Peak current

The current that a battery provides has to pass through ESR of the battery. The high ESR will provide the maximum current output. The lithium-ion battery has a typically high ESR than other batteries. So there will be less discharge of peak current.


How do you buy the best lithium-ion rechargeable AA batteries?

You can buy AA batteries online from any authorized distributor. Before buying you have to check different things related to the quality of the battery. Modern rechargeable batteries now come with high capacity to hold the charge for a year. You should know that the batteries should be tested through many radio control cars of children. Make sure that the charger available with the battery is perfect because a battery without a charger is like a cup without a tea. There are many batteries available on stores that can be charged more than one thousand times. You should check the capacity of the battery in mAh before buying. The capacity must be more than 19900 mAh for the best li-ion battery. This capacity gives you comfort in using it. There is no need to charge this battery often. Read all the specifications in the list.

How do you recharge lithium-ion AA batteries properly?

Charging and discharging is a chemical reaction. But in the case of lithium-ion batteries, it is quite different. For these, it is the energy flowing in and out due to the ion movement between the anodes and cathode. There are many parasitic reactions to electrolytes and electrodes that affect the recharging process.

These reactions include internal corrosion and the capacity of the ions to get trapped in the electrolyte. The Li-ion batteries are just like the lead-acid system. The Li-ion cannot accept the overcharge. It is a clean system that can accept energy when it needs. The lead-acid can cut off the voltage. The recharging process is easy and the full charge is present when voltages reach the threshold value. The lithium-ion batteries will be charged full as the voltage reaches the peak value but the saturation of the charges can take a longer time. A high current charger can fill the battery up to 70%. These batteries do not require a full-charged system.

If you use a low voltage threshold and eliminate the charge saturation then it will enhance the battery life but run time reduces. Use a compatible charger for your lithium-ion battery, if you use a low-cost charger. It will charge the battery in one hour but will not provide the saturation of the charges.

The state-of-charge will be reached after the completion of stage one charging. The battery at this point will be 85% charged but that will not contain an optimum amount of charges. This level of charging can be sufficient for many users but will not provide a long time use.
