24 v lithium-ion battery solar street lamps1

In the development of solar street lights, batteries have been a issue for people. In numerous battery, why choose lithium battery. Lithium battery with high energy storage density, relative to other batteries, lithium-ion battery energy density is high, at present has reached 460 - 600

in the development of solar street lights, batteries are always the concern of the people. Why in many batteries, lithium batteries? Compared with other batteries, lithium-ion battery energy density is very high, 460 - 600 watts/kg, is 6 - of lead-acid batteries Seven times. This means that the lithium battery lighter under the same charge capacity. According to the calculation, under the same volume of weight is about 1/5 of the lead acid products, 1/6. Relatively long service life and lithium battery service life can reach more than 6 years. With high power tolerance. Lithium battery solar street lamps * of charging and discharging rate can amount to 15 c - 30C。 Second, low self-discharge rate. No memory effect. This means that the solar street lamps of lithium battery can charge and discharge at any time, rather like tin nickel metal hydride battery and nickel batteries until run out of battery. High and low temperature flexibility. Lithium battery can be in - 40℃ - Use below 60 ℃, in - after the process 45 ℃. At last, the environmental protection. Used in production, or abandoned, it does not contain or generate toxic heavy metal material, such as lead, mercury and cadmium. So, choose the lithium battery of solar street light is a good choice.
