LiFePO4 Lithium Battery VS Lithium-ion Battery for Solar Energy System

LiFePO4 Lithium Battery VS Lithium-ion Battery for Solar Energy System

With the widespread use of the solar energy system, people would like to purchase much better and cheaper equipment, especially LiFePO4 lithium battery as energy storage batteries. However, there are a lot of different batteries for choose.

Here we will help you figure out which one is better to store power: LiFePO4 lithium battery or lithium-ion battery?


liFePO4 battery

Lithium Iron Phosphate Battery (LiFePO4 Battery) is a newer type of battery gaining recognition in the manufacturing industries for its higher power output, faster charging, lighter weight, and longer life. It is majorly used in RVs, golf cart, marine, boats, and off-grid homes,etc. While the LiFePO4 battery isn’t great for tiny devices like watches. Because they have a lower energy density compared to other lithium-ion batteries.

The following are its advantages:

Long life span: You can use it for longer. In fact, you can use a high-quality LiFePO4 battery for many years longer than other types of batteries. It lasts for about 5,000 deep cycles, which can last almost 10 years.

Safety: Equipped with BMS system, Lithium iron phosphate batteries do not decompose,collapse, heat up easily, or form strong oxidizing substances when it is at high temperatures or overcharges. LiFePO4 batteries is incombustible. It can withstand high temperatures without decomposing. It’s not prone to thermal runaway, and will keep cool at room temperature.

Excellent performance: The LiFePO4 battery will reach full charge in 2 hours or less.

The self-discharge rate when not in use just only 2% per month.When it comes to runtime, LiFePO4 battery is higher than lead acid batteries and other lithium batteries. With these high performance No maintenance needed.


Lithium-ion Battery

Lithium-ion batteries are an advanced battery technology that utilizes lithium ions as a key component of their electrochemistry. During the discharge cycle, lithium atoms in the anode are ionized and separated from their electrons. Lithium ions travel from the anode, through the electrolyte, until they reach the cathode, where they recombine with electrons and are electrically neutralized. Lithium ions are small enough to pass through a microosmotic separator between the anode and cathode. That's partly because lithium is small.

Lithium-ion batteries offer many advantages over other high-quality rechargeable battery technologies :

Large capacity: The battery has twice the capacity of the equivalent nickel-cadmium battery, making it more suitable for long-term communication. Conventional lithium-ion batteries have a voltage of 3.7V, three times that of nickel-cadmium and nickel-metal hydride batteries.

Strong charge retention abilityit is allowed a wide operating temperature range. After 30 days of open circuit storage at (20±5)℃, the discharge capacity of the battery at room temperature is greater than 85% of the rated capacity. Lithium-ion batteries have good discharge performance at both high and low temperatures, and can reach -20ˉ+60℃. The high temperature and discharge performance are better than those of other cell types.

Long cycle life: Lithium-ion batteries use carbon anodes. In the process of charging and discharging, the dendrite lithium will not appear in the carbon anode, so as to prevent the damage of the internal dendrite lithium short circuit to the battery. After 1200 times of continuous charging and discharging, the battery capacity is still no less than 60% of the rated value, far higher than other types of batteries, with long-term economic use.

Eco-friendly: It does not contain cadmium, lead, mercury and other harmful substances, is a clean green source of chemical energy.

Lightweight: Typically, lithium-ion batteries have more than twice the specific energy of nickel-cadmium batteries. Compared with nickel-metal hydride battery with the same capacity, the volume can be reduced by 30% and the weight can be reduced by 50%, which is conducive to small and light portable electronic equipment.

So which one should you choose?

After the particular comparison, it is clear that they have their unique advantages. When you want to buy batteries for large equipment and need to use for a long while, then lithium batteries will be your best choice. If you want to buy batteries for tiny equipment and don;t want to pollute environment, lithium-ion battery is the right answer. So if you want to purchase batteries for solar battery energy storage system, come and choose LiFePO4 lithium battery.
