What are the important advantages of lithium batteries? What are its shortcomings?

1. They are generally much lighter than other rechargeable batteries of the same size. The electrodes of lithium batteries are composed of lightweight lithium and carbon. 2. Lithium is also a highly active element, which means that a lot of energy can be stored in its atomic bonds. This means that the energy density of lithium batteries is very high. 3. A typical lithium battery can store 150 watt-hours of electricity in a 1 kg battery. Ni-MH battery packs (Ni-MH Ni-MH) can store 100 watt-hours per kilogram, and lead-acid batteries can only store 25 watt-hours per kilogram. Using lead-acid technology, it needs 6 kilograms to store the energy that a 1 kilogram lithium battery can handle. Lithium battery packs will only lose 5% of their electricity per month, while nickel-hydrogen batteries will lose 20% every month. 4. They have no recall effect, which means that you don't have to discharge completely before charging, like some other battery chemistries. Lithium batteries can handle hundreds of charge/discharge cycles. This is not to say that lithium batteries are perfect. They also have some shortcomings: 1. Regardless of whether you use them or not, they can only be used for two to three years from the date of production. 2. They are extremely active to high temperatures, and the heat will cause the lithium battery pack to degrade faster than under normal conditions. Assuming you completely discharge the lithium battery, it will be damaged. 3. The lithium battery pack must have an onboard computer to manage the battery. This makes them expensive.
