Of the lithium battery, thereby laying the foundation for a Wireless Society back in the nineties. The battery Stores Energy by separating positive and negative charges, positive in one place negative to another. How many separated charges can be created in units of volume. And how long they can exist in this form determines the quality of the battery itself. The nutritional parameter of a lithiumion battery is high energy density, which allows our gadgets to work for a long time without recharging, modern lithiumion batteries store about 280 watthours per kilogram, while leadacid batteries are well known to you. Well, about 40. Now for a kilogram for everyone times more energy, you can store per unit mass. Another advantage is the work, at a variety of temperatures, lithiumion batteries can be used from minus forty to plus 50 . In addition, lithiumion batteries are the lightest. But despite all these advantages of lithium, there are also disadvantages that have not been completely eli
