When considering buying batteries, lithium batteries are the first choice for most people. Among lithium batteries, NMC and LiFePo4 Battery are the main types of lithium batteries chosen. So, what are the differences between these two types of lithium batteries?
There are significant differences in application and performance between these two types of batteries. The following article will analyze their advantages and disadvantages in detail from several aspects such as safety, service life, and environmental sustainability to help you understand these two batteries as much as possible. type and choose the battery that better suits your needs.
LiFePO4 battery is lithium iron phosphate battery, which uses phosphate as the cathode material. Iron and phosphate are used instead of nickel and cobalt, making the battery cheaper to manufacture than nickel-based batteries. The energy density of this type of battery is relatively low, making it more suitable for standard or short-range electric vehicles. Lithium iron phosphate batteries use low-resistance materials, are safer and more stable, and have a long service life, so they can also be used in solar energy storage and off-grid systems.
Based on the above understanding, let us analyze and compare the differences between the two in terms of safety, service life, environmental sustainability, etc., and why LiFePO4 is a better choice for home battery storage together with solar photovoltaics.
The full name of NMC battery is lithium manganese cobalt oxide battery, which uses a combination of nickel, manganese and cobalt as the cathode material. Because of its high energy density and high power output, it is more suitable for applications such as portable electronic devices and electric vehicles. However, because the transition metal materials used in the positive electrode of NMC batteries, especially nickel, have high activity, people also have certain concerns about the safety of this battery.
1. High safety
LiFePO4 batteries have built-in overcharge and over-discharge protection circuits, which makes LiFePO4 batteries have higher thermal stability than other batteries, can withstand high voltage use for a long time, are less prone to thermal runaway, overheating and other safety issues, and are less likely to cause thermal runaway, overheating and other safety issues. Short circuits can occur and cause electrical fires and are best suited for use in domestic and commercial locations where safety is critical.
2.Long service life
One of the main advantages of LiFePO4 batteries is their durability and long service life. LiFePO4 batteries typically have a cycle life of 2,000 times. The LiFePO4 batteries provided by CXJPowers have a cycle life of more than 6,000 times. When choosing solar energy storage for your home, it's important to choose batteries with a long lifespan.
*Cycle life refers to the number of charge and discharge cycles that a battery undergoes under specified charge and discharge conditions when its capacity or performance drops to a specified percentage of the initial value after experiencing multiple complete charge and discharge cycles.
3. Environmentally sustainable
LiFePO4 batteries do not use the same toxic chemicals and harmful heavy metals (such as cobalt or nickel) found in other batteries. Therefore, LiFePO4 batteries are more Eco-friendly and easier to recycle.
4. Low maintenance
LiFePO4 batteries are designed and produced to reduce battery degradation rates. Once a LiFePO4 battery is installed, you don't need to worry about proactive maintenance to extend its life.
5. Can work normally in the environment of -20℃-60℃
LiFePO4 batteries are rugged and can operate effectively and efficiently at high and low temperatures from approximately -4.4°C to 70°C. This makes them ideal for home/commercial use in most geographical locations and climates.
6. Compatible with solar charging
This type of battery is highly compatible with solar storage systems and is constructed and designed to easily plug-in with solar panels.
In some cases, the initial cost of purchasing and installing an LiFePO4 battery may be higher than other batteries, but this is usually offset by a longer service life and lower maintenance costs.
While LiFePO4 cells are more suitable for use in solar storage systems, there are situations where NMC is a more popular choice.
NMC batteries have higher energy density, which means they can store more energy in a smaller space. This makes them ideal for use in small applications where space and weight are a priority, such as portable electronics, tools and electric vehicles.
The industry often discusses and compares NMC and LiFePO4 together. NMC is worrisome due to safety and thermal runaway issues. So in terms of home or commercial battery storage, is LiFePo4 always the winner?
The debate continues to rage among industry experts and is likely to continue for some time. But when it comes to solar cell storage, LiFePO4 is widely considered the better choice, which is why many top battery manufacturers are now choosing this chemistry for their energy storage products.
Which type of battery you choose depends on your specific needs. If you need a battery that is safe, reliable, and has a long service life, LiFePO4 batteries may be your best choice. However, if you need a battery with higher energy density for small applications, NMC batteries may be better for you. No matter which type of battery you choose, you should pay attention to its safety, reliability, and performance, and consult a professional to ensure you make the best choice.
