About Lithium Batteries
Probably the most advanced storage technology that marketed across the globe is Lithium batteries. As the name suggested, lithium ions act as electron discharging agent that move from the negative electrode positive electrode, and back when charging. The Lithium batteries utilize an interpolate lithium compound as positive material at the electrode and typically graphite at the negative electrode.
On the positive note, these batteries have a high energy density, and low self-discharge make it ideal to incorporate with all the battery inverters. Moreover, these batteries areequipped with safety procedures since they contain a flammable electrolyte, and if damaged or incorrectly charged can lead to explosions and fires.
