Choosing the correct battery is a task when we are bombarded with a lot of choices. Especially, when it comes to Lithium-ion batteries, which are the current buzz in the battery industry. Lithium-ion batteries are one of the most technologically advanced batteries that we have. Many of the lithium-ion battery manufacturers make high quality batteries leaving us with confusion to choose which one to buy.
What are lithium-ion batteries in the first place?
Lithium-ion batteries are rechargeable batteries which means they are not disposed of once they are used but they are charged again to be used later on. John B. Goodenough is known as the father of the lithium-ion battery technology.
These batteries are widely used commercially like in mobiles, laptops and other such electronic equipment. These days they are being used for electric vehicles as well.The earlier lithium batteries used metallic lithium and theory were disposable but the lithium-ion batteries used lithium compound as one of the electrodes in the battery.
Most of these batteries differ from each other according to the way they are manufactured by the battery manufacturers. The core design remains the same but some improvisations are done by the company which manufacturers them like additives are added to improve the battery’s performance. Compared to their lead acid counterparts, the lithium ion batteries are much lighter, efficient and have more power storage.
Working of lithium ion battery
The lithium-ion battery has mainly 4 parts namely:
1.Anode
2.Cathode
3.Separator
4.Electrolyte
When the battery is being charged the lithium ion moves from the cathode to the anode via the electrolyte and the reverse happens during discharging. The cathode or the positive electrode is usually a lithium oxide material while the anode is graphite. The electrolyte is non aqueous and normally contains organic liquids.

Why choose lithium-ion batteries?
They have a wide variety of benefits and advantages over the other conventional batteries being used. The primary features of the lithium-ion batteries that sets them apart from others are:
1.High energy-to-weight ratios,
2.high open circuit voltage,
3.low self-discharge rate,
4.Light in weight
5.Longer lifecycle
6.High operating temperature.
7.Store high capacity power
Things to consider before choosing the right lithium ion battery:
In the market there are a lot of varieties and options available while buying the lithium ion batteries. How to choose the right one is a challenge. Keep the following points in mind while making the right purchase.
1.Power you need: First check and estimate how much power you need and the time duration, be it your homes or vehicles or equipment. If your power requirement is large and for a continuous period of time, try investing in a battery that offers the desired power supply steadily for hours. Also calculate where you want to use it for and how.
2.Rate of charging: The rate of charging depends how fast the battery gets charged safely. Sometimes the battery takes a long time to charge before they can be used. This hinders the overall productivity as there is a waiting period that needs to get over. But be beware of chargers that offer to fast charge your battery, they could do more harm than good. Always use the charger that comes with the battery pack and make sure they are a genuine piece. Never charge your battery in a hurry and follow all the precautions while charging it
3.Range of operating temperature
Every lithium ion battery is different and hence you need to read the label of the battery before making sure about its details. Check at what temperature range you will be operating your battery and make sure the one you brought can be used in that temperature range.
4.Lifespan:
No battery runs for the entire life but has an expiry date. Check the expiry date before making the purchase. Lithium ion batteries have an inherent longer life due to its chemistry but every battery differs from each other depending on the type, specifications and the way they are made. High quality batteries will last longer since they are made of fine materials inside. Hence opt for the lithium ion batteries with longer life.
Tips to take care of the lithium ion battery:
1.Dont’t overcharge the batteries
Take care not to overcharge the batteries. Different batteries with different voltage and capacities charge at different speeds so the time would differ. Don’t keep the batteries that charge in around 2 hours, charging for overnight.
2.Never deeply discharge them
Don’t use more than the prescribed limit of your battery’s capacity.
3.Use the correct battery charger
Always use the genuine right battery charger that comes with the battery .
4.Handle with care
Don’t drop, cut, tear or roughly handle them
5.Potect from water, fire and heat
Keep them in a place away from water, fire and heat.
Also maintaining and taking care of the batteries goes a long way for the longer lifespan of the batteries.
