A lithium-ion battery stores energy through a chemical reaction that occurs between its two electrodes: a positive electrode, called the cathode, and a negative electrode, called the anode. During charging, lithium ions move from the cathode to the anode through an electrolyte, which is a conductive solution.
Lithium-ion batteries use lithium ions to create an electrical potential between the positive and negative sides of the battery, known as the electrodes. A thin layer of insulating material called a “separator” sits between the two electrodes and allows the lithium ions to pass through while blocking the electrons.
A lithium-ion battery is a type of rechargeable battery that uses lithium ions to store and release electrical energy. It is commonly used in portable electronic devices such as smartphones, laptops, and electric vehicles. How does a lithium-ion battery store energy?
Lithium-ion cells can be manufactured to optimize energy or power density. Handheld electronics mostly use lithium polymer batteries (with a polymer gel as an electrolyte), a lithium cobalt oxide (LiCoO 2 or NMC) may offer longer life and a higher discharge rate.
During charging, lithium ions move from the cathode to the anode through an electrolyte, which is a conductive solution. This process allows the battery to store energy.
Lithium-ion batteries have changed our world. 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.
