Advantages and Disadvantages of Lithium ION Batteries

Lithium-ion batteries (LIBs) are incredibly popular nowadays. Today, lithium-ion batteries are one of the most successful and secure battery mysteries. About two billion cells are generated from such batteries each year. These are one of the most powerful rechargeable batteries. Popular because lithium-ion batteries have several important advantages over competitive technology:


Lithium ion batteries are not dependent on any chemical reaction for electrolysis. Rather it depends on the flow of lithium ions between the cathode and the anode. This is the biggest advantage of lithium ion batteries. Moreover, fast charging, relatively cool, low weight is also one of the reasons for the popularity of this battery.


Lithium ion batteries first came on the market about 28 years ago. Since then, small size light weight lithium ion batteries have become increasingly popular. Not only that, as long as the world wants to lean towards battery-powered cars. And in that case also a helpful lithium ion battery. Needless to say, the importance of lithium ion batteries in human society is immense.


Advantages of lithium ion batteries:



  1. Lithium ion batteries has more density

  2. Light weight and easy to carry

  3. Produces more voltage than any other rechargeable battery

  4. There is no risk of accident as no harmful liquids are used in it

  5. It charges very fast so the electric bill always remain low.

  6. Much lighter than other types of rechargeable batteries of the same size.

  7. Lithium-ion batteries retain their charge for long periods of time and lose only 5 percent of their charge per month, compared to 20 percent per month for NiMH batteries.


Disadvantages of lithium ion batteries:



  1. The price is higher than other equivalent batteries

  2. If the battery is not used for a long time, it will not return to normal charge.

  3. Large charges can cause short circuits

  4. The batteries started deteriorating as soon as they left the factory. Whether we use them or not, they will last only two or three years from the date of production.

  5. They are very sensitive to high temperatures. Lithium-ion battery packs degrade much faster than usual due to heat.


Various lithium-ion battery-ratings used in the market:


Volts and Amps: Let's not go into too many confusing details. Let's take a brief look at the fact that voltage pushes the flow of electrical energy, while measuring the force with amps. Typically, higher voltage electric bikes run faster, while higher amps require thicker wires or more powerful and larger battery packs.


Voltage: How fast an electron moves depends on the voltage. Single volt (VOLT)


Amps: The flow of electrons is called current and its single amps (AMPS)


Watts: A combination of volts and amps (volts * amps = watts) watt = volt * amps


What does AH mean in a car battery?


The full form of 'AH' mentioned in the battery is ampere-hour and it refers to the capacity of a battery to deliver uninterrupted current over a period of time (12 hours for a Class C12 battery and 20 hours for a Class C20 battery).


So if these words written on a battery:


Motor rating :   250 watt               watt= volt*amps


Voltage = 60 v ( 12*5)


Current rate : 55 Ah(Ah/backup time = current)


Backup time: 12 hrs


Batarry charging time : 4.5 hrs


Battary warranty : 3 years


It goes without saying that 5 batteries of 12v come with a total of 60V, 55Ah car battery means if it guarantees to provide 4.5A [55/12 = 4.5A] current for 12 hours backup time and it gives 250 ~ 270watt motor [4.5x60 = 270 watt] Can provide 12 hours backup for maximum load. Battery life is 3 years.


We will select the battery according to our needs by looking at the rating from the battery body above. The price will also be different depending on the rating.
