What Is A Lithium Battery?

Many people like you wonder what is lithium. Meaning they want to know the difference between lithium batteries and other types of batteries like lead acid.

So what exactly is a lithium battery?

A lithium battery, also known as a lithium-ion (Li-ion) battery, is any type of battery that uses the mineral Lithium as one of the main components in its construction. Lithium batteries are known for their light weight and long lifespans and are used in many applications, from mobile phones, laptops, electric vehicles to solar generation.

Lithium-ion batteries typically follow the same design consisting of a cathode (positive electrode) made of some kind of Lithium metal, an anode (negative electrode) made of Graphite or Silicon, and a lithium salt as the electrolyte.

Some of the more notable types of Lithium-ion batteries are:

●Lithium Iron Phosphate LFP (LiFePO4)

●Lithium Cobalt Oxide LCO (LiCoO2)

●Lithium Manganese Oxide LMO (LiMn2O4)

●Lithium Nickel Cobalt Aluminium Oxide NCA (LiNiCoAlO2)

●Lithium Nickel Manganese Cobalt Oxide NMC (LiNixMnyCozO2)

●And more…  

Since the 1960s Lithium batteries have gone through many changes with each successive generation being better in terms of cost, lifespan, energy density, and other aspects.

Nowadays, in solar energy circles, LiFePO4 (LFP) batteries are the best lithium-ion batteries on the market, boasting many areas where they are superior to other lithium and lead-acid batteries.

What is a Lithium Iron Phosphate LiFePO4 battery?

An LFP or LiFePO4 stands for lithium iron phosphate. If you are wondering where the ‘F’ comes from. It comes from Ferrum, the Latin word for Iron. LFP batteries have a Lithium Iron Phosphate cathode and Graphite anode, which gives them a lower energy density in exchange for increased safety and better performance in other aspects such as discharge rate.

So how does an LFP battery stack up to other lithium-ion batteries?

How long do lithium batteries last?

Roughly speaking, depending on the quality and type, your lithium battery can last anywhere from two to over ten years. More affordable lithium-ion batteries typically have between 500 and 3000 life cycles. While premium Lithium Iron Phosphate LFP batteries can last anywhere from 3500 to over 4000 cycles. 

Other external factors also influence the performance and lifespan of your batteries. Therefore, proper storage and use will protect and preserve your batteries so they last longer.

When not being used, it’s recommended to store your batteries in a cool, dry place away from direct sunlight and heat. When recharging, you should follow the manufacturer’s instructions to prevent overcharging, misconfigurations and other actions that can negatively impact battery life. Doing this will ensure your battery will last for the longest possible time.

How To Take Care Of Lithium Batteries?

Lithium batteries are a powerful and versatile energy storage device but they can wear out over time. That’s why it’s important to take proper care of them because otherwise, they won’t last long.

Here are some tips on how to take care of your lithium batteries:

1.Store Lithium Batteries Properly – It’s important to store lithium batteries correctly so that their chemical properties remain the same. Keep the battery away from extreme temperatures, humidity and direct sunlight.

If you are going to store the battery for a long time, we recommend you store it at an SoC (state of charge) between 30% to 50%. Don’t put away the battery at 100%.

2.Balance Partial Charge & Discharge Cycles – To enjoy the best Lithium-ion battery lifespan do not discharge your batteries completely. Lithium batteries perform best when they experience balanced cycles of charge and discharge. In short, don’t leave your battery full and don’t 100% discharge your batteries all the time.

3.Avoid Overcharging – Overcharging causes more strain on your lithium battery than normal usage does. Excessive voltage speeds up the degradation of your batteries.

4.Avoid Extreme Heat or Cold – Lithium batteries don’t perform well in extremely cold or hot environments. So if you plan to use a Lithium battery outdoors, make sure the environment is within the recommended optimal thermal range of the battery. 

5.Handle with Care – Always keep careful track of where your battery is placed. Avoid dropping or bumping the battery since severe impacts can damage the battery.

By following these tips and tricks for taking proper care of your lithium-ion battery, you’ll be able to max out your battery pack’s lifespan.
