![]() ![]() The battery management system monitors the health and temperature of the battery. At the top of each charge, the BMS also balances the energy across all of the cells and helps ensure you get the maximum life and performance out of your lithium-ion battery. The inside of an individual lithium-ion cell is relatively simple. There are four main components: The anode, the cathode, an electrolyte, and a separator. The negative electrode in a cell is called the anode. During charging, the lithium ions move from the cathode, through the separator, to the anode. The most popular material used for the anode is graphite. Common materials for the cathode are lithium cobalt oxide, lithium iron phosphate, and lithium manganese oxide. These different chemistries provide different benefits and voltages. The role of the electrolyte inside of a lithium-ion battery is to help transport the positive lithium-ions between the anode and cathode. The most common electrolyte inside of a lithium-ion battery is a lithium salt. What is a Separator?īetween the anode and cathode is the separator. The separator is a thin sheet of material that allows the lithium ions to pass through but doesn’t conduct electricity. It prevents the anode and cathode from shorting together electrically and forces the electrons to flow through your electronic device, giving it power. The separator also plays an important safety role. If the separator gets too hot, the pores close and prevent the lithium ions from passing through. Stopping the transport of the ions shuts down the battery cell, which can help prevent damage to the battery or a fire. Its easy to see how lithium-ion batteries have changed our world as they are used everywhere. They last much longer and store more energy than any previous battery type. However, this does not mean that manufacturers cannot improve these batteries. ![]() Here at Dragonfly Energy, we assemble the highest quality energy storage lithium-ion batteries utilizing conventional cells. ![]() While this current technology is changing the energy storage world, we did not stop there. We are actively working on the next generation of lithium-ion technology.įrom working on developing solid-state batteries that last longer and pack more energy to revolutionizing the manufacturing process our R&D team is looking to the future of energy storage. ![]()
