Batteries that have lithium as their anode are called lithium batteries. The charge moves from anode to cathode during discharge and cathode to anode during charging. Lithium batteries were introduced way back in 1980-1990s.
These batteries have completely revolutionized the portable electronics market such as cellular telephones and laptop computers. Today 18650 lithium ion battery are finding increased applications in electronics, electric cars, and solar markets.
Given its lightweight, high energy density and efficiency, lithium batteries are used in a wide range of portable consumer electronic devices, medical equipment, power backups, solar storage and in electric vehicles.
Solar is already cheaper than coal and this trend will only accelerate. However, the biggest problem with solar systems is that they must rely on the power grid to store excess power generated during the day and takes power from the grid at night.
This is done because the electricity network acts as a free source of energy storage for solar panel systems. However, the industry soon realized that this was not a viable option in the long term as the utility is the biggest competitor to diesel. Therefore, they started using self storage option to support the flawless work of the solar system.
Plus solar energy storage has been gaining traction because of economic encourage faster adoption of solar system is paired with a lithium battery. These batteries are very versatile and in addition to save energy for the home, they can also be used in the wholesale energy market to provide the capacity and frequency regulation.
