Comparison Between Lithium Iron Phosphate Battery and Ternary Lithium Battery

Batteries play a very crucial role in the development of the modern world. They are the reason we are enjoying easy communication and staying in touch with the rest of the world. This is because batteries power all the electronic devices used in different areas to improve human life.

It is no wonder there has been so much development and revolution in the battery market. Today, a wide range of batteries are designed to meet specific user needs.

Lithium-ion phosphate (LFP) and ternary lithium batteries are two of the most common option on the market today. They are powerful batteries with high-performance features and great longevity.

Today, we look at what these batteries are and what makes them different from each other. This information should help you make more informed decisions when buying.

What Are Lithium Iron Phosphate And Ternary lithium batteries?

The best way to get the most from any battery is to understand what that battery is and how it works. LFP and ternary lithium batteries may be new terms to some consumers. This will make it very hard to decide which option is best for a particular need.

There is lots of information on the internet explaining the batteries. Unfortunately, some of it is too complicated, and you may not understand it well. But don’t worry; we have broken down the definitions to make them more understandable.

Lithium-ion Phosphate Batteries

All lithium batteries have lithium metal as one of their main components. However, there are specific features that make one different from the other. For LFP batteries, they come with lithium-ion phosphate as the cathode material, hence, their name.

The cathode materials for Li-Ion batteries are mainly lithium cobalt oxide, lithium manganese, lithium nickel oxide, ternary materials, and lithium iron phosphate, among others. So, the cathode material determines the battery’s name and its performance.

LFP batteries promise the longest service life, with over 4000 charge cycles up to 80% DOO. These batteries can work for over ten years in the right conditions, which has made them extremely popular. Their large capacity and general safety also contribute to their popularity and use.

Ternary Lithium Battery

Ternary lithium batteries may not be the most common option for most consumers, but they are pretty amazing. They are a type of lithium-ion battery containing three transition metal oxides; nickel, cobalt, and manganese on the electrode. Also, the batteries bring out the best performance of lithium cobaltate, combining it with the high specific capacity of nickelate and the safety of manganate.

In short, it is one of the best lithium-based batteries on the market today. The ternary battery is currently among the most popular options and growing at the fastest rate. It is the battery you want to use when you need the best performance.

Comparison Between Lithium Iron Phosphate Battery And Ternary Lithium Battery

As stated above, lithium batteries are categorized depending on the specific materials that make them unique. That is the main difference between LFP and ternary lithium batteries, and it determines how the batteries perform.

A comparison is necessary if you want to better understand these batteries and choose the perfect solution for your application. We have highlighted the main points of interest here, with a focus on what makes each option unique.

Endurance and Performance

The battery’s energy density carries the day when it comes to the endurance of new energy applications. LFP battery cells have an energy density of about 150Wh/Kg, while ternary batteries carry over 220Wh/kg. That means ternary lithium batteries have more endurance.

Thermal Stability

Another crucial factor to consider when looking for batteries is safety. And this comes up in the form of thermal stability. LFP batteries have the best thermal stability compared to ternary batteries and hence, are safer. The batteries can withstand temperatures as high as 350C, and the components will start decomposing at 500C, compared to 300C of ternary lithium batteries.

Efficiency in Charging and Discharging

A battery’s performance is often determined by its charging. Consumers want batteries that can charge faster and safer and discharge more slowly. In this case, ternary lithium batteries offer more efficiency.

Experiments have been done to compare these two solutions, and the results show a slight difference between them when charging under 10C. When the charging temperature rises above 10C, the difference becomes more apparent. At 20C, ternary lithium batteries maintain a constant current ratio of 52.57, while LFP batteries maintain 10.08%. That means ternary lithium batteries are five times more efficient.

Charge Cycles

When buying batteries, one of the biggest concerns for consumers always longevity. That means the number of charge cycles the battery delivers before it dies completely. It determines how long you can use your battery efficiently.

LFP batteries have better life cycles than lithium ternary batteries. The primary lifespan of a typical lithium ternary battery is 2000 cycles, although its capacity reduces to 60% at 1000 cycles. Even the best ternary lithium battery, like the one from Tesla, can only keep 70% efficiency after 3000 cycles. LFP batteries, on the other hand, will still have 80% capacity efficiency at the same point.

Summary

Both lithium-ion phosphate and ternary lithium are good battery solutions. LFPs are generally safer, longer lasting, and more resistant to temperature. Ternary lithium batteries are lighter, offer more charging efficiency, and have lower temperature resistance. Therefore, each option will only perform best under specific user conditions. In other words, it matters more where you are using the battery.

Application Of Lithium Iron Phosphate Battery And Ternary Lithium Battery

Lithium-ion phosphate and ternary lithium batteries are common options for new power vehicle systems. The higher power density of LFPs makes them ideal for medium-power applications like robotics, AGV, E-mobility, last-mile delivery, and so on. They are also applicable in heavy-duty environments like marine and industrial vehicles, and using them in energy storage systems is possible.

Ternary lithium batteries can be used in daily consumer applications, power tools, portable items, EVs, and much more. They are powerful batteries with the ability to deliver excellent power and performance under any circumstance. Besides, several ternary lithium batteries are currently on the market, including 14500, 14650, 20700, and 21700, designed for specific uses.
