The role of lithium battery in solar street lamps system original solar road
Now lithium-ion batteries in the solar street light system for lithium battery light weight, large capacity, long service life of street lamp light pole base, high cost performance is more and more widely used, solar street light, solar lawn lamp, solar garden light in the solar system such as
at present, lithium batteries because of its light weight, large capacity, long life, high cost performance, lamp base, more and more widely used in solar street light system. Lithium battery is becoming more and more widely used in solar power generation system, such as solar street light, solar lawn, solar garden light, etc. The author according to own working practice and related theory, the lithium-ion batteries in the solar street light, solar garden light, solar lawn work principle, structure, advantages and disadvantages were briefly reviewed. , only supplies the reference. The working principle of lithium-ion battery lithium battery is usually use manganese dioxide as positive pole material, metallic lithium metal or its alloy as the cathode material, and using nonaqueous electrolyte battery solution. It is a secondary battery, can use two reversible embedding and take off a built-in lithium ion compound as the positive and negative respectively. Lithium-ion batteries produced by positive and negative electrode reaction electronic charge and discharge. When the battery cathode of lithium atom ionization into lithium ions and electrons, lithium ion to the anode movement and synthesize lithium atoms and electrons. When discharge, lithium atoms from the anode surface ionization of graphite crystal into lithium ions and electrons, and synthesize lithium atoms at the cathode. Therefore, in this kind of batteries, lithium always take the form of lithium ion, and do not take the form of metallic lithium. Therefore, this kind of battery is referred to as lithium ion battery. Charging the anode reaction is lithium cobalt acid lithium = = ( x) Cobalt acid lithium cobalt acid lithium + + + - xenon ( Electronic) Charge on the cathode reaction is 6 c + + + xenon - cobalt acid lithium = total response: lithium cobalt acid lithium rechargeable batteries lithium cobalt acid lithium + 6 c = ( x) + lithium cobalt acid lithium cobalt acid lithium lithium battery discharge and chemical reaction, discharge equation is lithium manganese dioxide = lithium cobalt acid lithium
