What Are Lithium Batteries?

View as

What is a lithium battery? As popular as they are, not many people know or fully understand these batteries. A lithium battery is a rechargeable battery that uses lithium ions as the main component of its electrolyte. In a more straightforward form, these batteries run most of our day-to-day electronics, including our laptops and mobile phones. There are different types of lithium batteries as well, which we will tackle later.

There are different types of lithium batteries as well, which we will tackle later.

More importantly, these batteries are known for their many advantages over other battery types. They boast a faster charging rate, a longer service life, and better stability, all in a lighter pack. This is why the lithium battery has become a staple in various applications, such as camping, off-grid, and home backup. 

Because of this, lithium batteries are typically more expensive, causing some people to hesitate to purchase them. Many opt for traditional lead-acid batteries instead, despite the many advantages they can get from using lithium as their portable battery pack for camping. Fortunately, several providers offer affordable yet high-quality lithium batteries, making these top-notch power packs more accessible. 

If you're currently looking for one, try an Outbax lithium battery. We have several of them here and they're not your typical batteries—they're lithium iron phosphate batteries or LiFePO4 batteries! Known as the best power pack type, these are hard to score at great prices, so don't miss your chance and check out our website today. 

Need a bit more background on lithium batteries before making a purchase? We got you. Read on and learn about these superb power packs before heading out to the nearest battery store!

How Does a Lithium Battery Work?

We're done with "What is a lithium battery?" Now, it's time to learn how these power packs operate. A lithium battery works by transferring lithium ions between the anode and the cathode during charge and discharge cycles. 

A lithium battery has four major components: the anode, the cathode, the electrode, and the separator. When the battery is charged, lithium ions are stored in the anode. When discharging, these ions leave the anode and move to the cathode, where they are absorbed into the cathode material.

Meanwhile, the electrodes allow this exchange of ions to go smoothly while the separator prevents contact between them to help avoid a short circuit. 

During charging, an external voltage is applied to the battery, causing li-ions to move from the cathode to the anode through the electrolyte, where they are stored. During discharge, when the battery supplies power, the process reverses: the ions move from the anode to the cathode through the electrolyte, creating an electric current that can power devices.

The movement of ions back and forth during charge and discharge cycles enables the lithium battery to store and release energy.

What Are the Different Types of Lithium Batteries?

There are six different types of lithium batteries. Let's look at each one, particularly the lithium iron phosphate batteries or LiFePO4 batteries, which are currently gaining traction for their superior build and performance. 

Lithium Cobalt Oxide

LCO batteries are mainly used for their ability to provide longer runtime. However, they have high specific energy but low specific power, making them unsuitable for high-load applications. 

Lithium Manganese Oxide

These batteries stand out mainly for their three-dimensional chemistry, which improves ion flow and lowers internal resistance. This improves stability and safety, making them a good option for power tools and medical instruments.

Lithium Nickel Manganese Cobalt Oxide

Due to the combined elements used in the cathode, this battery type boasts exceptional stability and high specific energy. NMC batteries are ideal for power tools and electronic vehicles like e-bikes.

Lithium Nickel Cobalt Aluminium Oxide

High in energy with a decent battery life, NCA batteries are popular in the electric vehicle market. However, they tend to be expensive despite not being as safe as other battery systems. 

Lithium Titanate

Unlike NCA, LTO batteries are extremely safe and have impressive lifespans. This is why they are widely used in telecommunication systems and even military equipment applications.

Lithium ion Batteries

Lithium ion batteries have been around for long and are still widely used today. In fact, they are so popular that they would often come up with a simple search of "what is a lithium battery" online!

Often mistaken as similar to the LiFePO4 batteries, this power pack stands out for its high energy density and low self-discharge rate, making them convenient for everyday use. 

However, the downside of a lithium-ion battery is that it's prone to overheating, which can lead to fires or explosions. The reason behind this is the lack of a battery management system, which is what our next battery's edge is all about.

Lithium Iron Phosphate Batteries

Finally, let's talk about the lithium battery that gradually reached the top. As mentioned earlier, LiFePO4 batteries have a good reputation in the battery industry. Dubbed the safest batteries in the market, these power packs are backed by a built-in battery management system (BMS), which helps increase battery protection and ensures a stable, reliable output. 

LiFePO4 batteries come in different capacities and voltage levels. Boasting unrivalled battery performance and ultra-portability, these battery packs are widely available online and in physical stores. In fact, every Outbax lithium battery we have is a LiFePO4 battery to ensure quality power output for all of our customers!

What Makes LiFePO4 Batteries Special?

Let's talk more about the lithium iron phosphate battery or LiFePO4 battery. If you ask a seasoned battery user, "What is the best lithium battery for a caravan?" the answer would most likely be a LiFePO4 battery. You're most likely to get the same answers if you ask regarding the best camping battery or even home backup battery. 

This is how good these power packs are. Need more convincing? Check out some of the top features that made the LIFePO4 batteries stand out among the different types of lithium batteries!

Built-in BMS

Efficiency and quality power made the lithium battery shine in the first place, but the LiFePO4 power pack took this to the next level with an integrated BMS. Thanks to the built-in system, you enjoy maintenance-free battery use as it optimises battery cells for smooth operation. 

More importantly, the BMS shields your battery from common issues such as overcharging, over-discharging, overheating, and short circuits. 

Safe, Eco-friendly Composition

LiFePO4 batteries comprise safer, non-toxic chemicals, making them a better choice for the environment. The lithium battery composition of these power packs is also less prone to catching fires and explosions, perfect for both seasoned and first-time battery users. 


LiFePO4 batteries charge significantly faster than other battery varieties, usually taking just 1-2 hours with AC power and 3-6 hours when using solar panels. The charging duration varies based on battery capacity, current flow, and the chosen charging technique.


Thanks to its high density, the LiFePO4 battery pack increased output in a lightweight form. These power packs are about four times lighter than a lead-acid battery but can be discharged by up to 80% for longer runtime. It's the perfect camping battery, off-grid battery, or battery backup in case of power outages!

Longer Lifespan

Although one LiFePO4 battery may cost more than two lead-acid batteries, they last twice as long. Proper maintenance can last up to a decade, making them a valuable investment, especially for those who use batteries regularly. 


The superior performance of the lithium iron phosphate battery (LiFePO4 battery) has made it a must-have for outdoor, work, or household backup purposes. It also has a wider operating temperature between -4°F and 140°F, translating to reliable performance under changing weather conditions. 

The continuous development in the lithium battery sector also made it a terrific pair of solar panels. Equipped with amazing energy storage capabilities, having a LiFePO4 battery alongside your solar panel will help you maximise the solar power you generate throughout the day for use during peak hours or in the evening.
