What Are Lithium Batteries

Lithium batteries are the most popular type of rechargeable battery. They’re also the most expensive. But not all lithium batteries are equal, so it’s important to know what makes the difference.

First off, lithium batteries are a chemical mixture, not a chemical formula. To figure out how much lithium you’ll need, you should get a sense of what a battery is made up of and the kind of use you can expect. That will help you choose your battery type.Lithium batteries generally aren’t cheap. They cost more than alkaline batteries because they have a lot more lithium than alkaline batteries do. You can expect to pay at least 10 percent more for lithium-powered devices.

Characteristics of Lithium Batteries

In short, lithium batteries are not interchangeable with alkaline batteries. But they have a few shared characteristics.

Both types of batteries have positive and negative terminals. However, lithium batteries are polymerized, which means they’re not composed of metals like aluminum and steel. The positive and negative terminals are covered with a material called a lithium-ion battery electrode, which has a thin oxide layer on the surface.

The oxide layer protects the cathode and anode from the electrolyte that carries electricity between them. This prevents an electric current from leaking out of the battery and causing a fire, but it also provides the cathode and anode with a protective coating. Both types of batteries also use a positive and a negative plate to form a cell.

Advantages of Lithium Batteries

Lithium batteries have the following advantages over alkaline:

Longer Battery Life: This is the big one. Lithium-ion batteries provide battery life that’s at least twice as long as that of alkaline batteries. Some lithium batteries can last up to 10 times as long.

Low Sodium: Lithium is a great alternative to lithium-ion. That’s because lithium-ion batteries are prone to exploding if you overcharge them. By comparison, lithium-ion batteries have a low-sodium electrolyte that helps prevent the build-up of flammable chemicals, as well as the potential for overheating.

Denser Battery: As with any battery, lithium batteries have a lower total energy density than a comparable alkaline battery.

Disadvantages of Lithium Batteries

The downsides of this type of battery include:

Lithium batteries are less compact than alkaline batteries.

Lithium batteries are more expensive than alkaline batteries.

Lithium batteries need to be recharged regularly.

What Are Alkaline Batteries

There are three main types of lithium batteries, each with different chemical compositions. The alkaline batteries include:

AA alkaline batteries: These batteries are similar to AA batteries, but their chemistry has been altered. Instead of carbon, these batteries use a silicon ion. They are not rechargeable, which means you’ll have to buy new ones regularly.

Characteristics of Alkaline Batteries

You probably have seen the warnings on your box of batteries or taken a look at the battery label on your electronics and seen one of the words – alkaline or alkaline-carbon. Alkaline batteries store energy in the form of carbon. Unlike lithium batteries, they have no liquid electrolytes and the carbon (a water-based compound) cannot conduct current.

You can see here that these batteries store energy in carbon, which can then be discharged and recharged by applying electricity to the electrodes. The battery’s discharge and recharging characteristics are therefore very different from alkaline batteries, which store energy in acid. Many commercial computers use alkaline batteries because they are inexpensive and safe.

Should You Use Lithium or Alkaline Batteries?

While both types of batteries are popular, the answer to this question may change depending on your personal preferences.

While there’s no right answer, if you’re planning on using an electric car or a solar panel in your home, then you may want to stick to a lithium-ion battery. These rechargeable batteries have a longer lifespan, are more cost-effective and are safer to charge than alkaline batteries.

But for regular use, you may want to stick with an alkaline battery. These batteries will typically have a higher energy density, which means they have a larger amount of total charge.

What's the Difference Between a Lithium Battery and Alkaline Battery?

There’s a big difference between the two types of batteries—and it's best to know which one you need for your electronics.

Lithium-ion batteries are like your laptop computer or smartphone. Lithium ions (the building blocks of the battery) sit at the bottom of a container of liquid lithium and are surrounded by an electrolyte. This barrier gives the battery its name, the lithium ion.

They charge quickly, and there's no fire risk, as there are no explosives inside the battery. Most laptops and cell phones are made from lithium-ion batteries, though alkaline batteries have a higher capacity and can also be used in smaller devices. Lithium-ion batteries have a relatively short life span and will eventually degrade and require a charge.

Can You Replace a Lead Acid Battery with a Lithium Battery?

No. No matter how good a deal you can get on an alkaline battery, or how much cheaper it is to replace a lead acid battery than it is to buy a new one, you can’t just swap a lead acid battery in for a lithium cell..

Is Lithium Better for Battery Technology Than Lead Acid?

That depends. Lithium has many advantages as a battery material, compared to lead acid. For one, lithium is an excellent battery alloy. By combining two metals, lithium gives the anode a stable structure that’s more reliable and less prone to wear and tear. Another advantage of lithium: its reactivity with oxygen.

Conclusion

Lithium and alkaline batteries are two very different types of battery. Which one is right for you depends on the type of device you’re powering, the types of uses you may be providing for the battery, and what you expect the battery to last for.
