Advantages and disadvantages of lithium batteries

Lithium batteries have many obvious characteristics, first of all: (1) High working voltage. The operating voltage of lithium batteries is 3.6V, which is three times the operating voltage of nickel-hydrogen batteries and nickel-cadmium batteries. Higher than energy. The specific energy of lithium batteries can reach 150Wh/kg, which is 3 times that of nickel-cadmium batteries and 1.5 times that of nickel-hydrogen batteries. (2) Long cycle life. At present, the cycle life of lithium batteries has reached more than 1,000 times, and can reach tens of thousands of times at low depths of discharge, which is many times that of other secondary batteries. The self-discharge rate is low. The monthly self-discharge rate of lithium batteries is only 6-8%, which is much lower than nickel-cadmium batteries (25-30%) and nickel-hydrogen batteries (15-20%). (3) No memory. It can be charged at any time according to the need without affecting the battery function. No pollution to the environment. Lithium batteries do not contain harmful substances and are veritable green batteries. Can be made into any shape. Therefore, Tesla should be a model of the benefits of lithium batteries. Lithium batteries also have certain shortcomings. First of all, the performance is: (1) The cost is too high. First of all, the price of the cathode material LiCoO2 is relatively high, but from the point of view of the price per watt hour, it is now lower than the nickel-hydrogen battery, equal to the nickel-cadmium battery, but higher than the lead-acid battery. (2) A special protection circuit must be supplied to prevent overcharging. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
