Wholesale Lithium-Ion Battery for PV Systems?
Simply put, a lithium-ion battery (commonly referred to as a Li-ion battery or LIB) is a type of rechargeable battery that is commonly used for portable electronics and electric vehicles. The popularity of this kind of battery is also steadily growing for military and aerospace applications.
In a lithium-ion battery, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging. Additionally, lithium-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode.
Advantages of a Lithium-Ion Battery?
The lithium-ion battery offers so many benefits to a lot of electrical devices and appliances. The following are the most commonly known advantages of a lithium-ion battery:
- It has a high energy density, and it has the potential for yet higher capacities.
- It does not need prolonged priming when new. One regular charge is all that is needed.
- It has a relatively low self-discharge. In fact, its self-discharge is less than half that of nickel-based batteries.
- It is a low-maintenance battery. No periodic discharge is needed, and there is also no memory.
- It has specialty cells that can provide a very high current to applications like power tools.
Why Are Lithium-Ion Batteries Better for Solar Products than Lead-Acid Batteries?
The lead-acid battery is the oldest rechargeable battery in existence, and it also costs less upfront. However, despite that advantage, lead-acid batteries require regular maintenance and don’t last as long. These characteristics are some things that aren’t present in lithium-ion batteries.
For one thing, lead-acid batteries can only handle up to 50% depth of discharge. Beyond that point, there is a risk of negatively affecting their lifespan. On the other hand, lithium-ion batteries can handle deep discharges of 80% or more. This essentially means they feature a higher usable capacity.
Moreover, lithium-ion batteries are simply more efficient than lead-acid batteries, which means that more solar power can be stored and used in lithium-ion batteries. Lead-acid batteries are only 80%–85% efficient, depending on the model and condition. This means that if there are 1,000 watts of solar coming into the batteries, there are only 800-–850 watts available after the charging and discharging process. Meanwhile, lithium-ion batteries are more than 95% efficient. In other words, using the same example, there will be over 950 watts of power available with lithium-ion batteries.
And in addition to better storage for solar power, higher efficiency also comes with a faster rate of charge for lithium-ion batteries. They can handle a higher amperage from the charger, which means that they can be refilled much faster than lead-acid batteries.
Because of all these reasons, lithium-ion batteries have been proven to be the best choice of batteries when it comes to solar power. They do cost more upfront, but their price is worth it because they definitely get the job done right.
