The latest street lamp

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 have been closely watched. Of all the batteries, lithium batteries is why? Lithium battery energy density high, compared with other battery is very high, 460 - 600 watts/kg, is 6 - of lead-acid batteries Seven times. This means that under the same charge capacity, lithium batteries are lighter in weight. According to the calculation, the equivalent volume of 1/5 of the weight, weight is about lead acid products 1/6. Relatively long service life and lithium battery service life can reach more than 6 years. High power endurance. Solar street lamps lithium battery charge and discharge ratio can reach 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 than waiting like tin nickel metal hydride battery and nickel battery power runs out. The high and low temperature has a strong adaptability. Lithium battery can be in - 40℃- Use below 60 ℃, in - after the process 45 ℃. Finally, it is green. In production, use or waste, does not contain or generate toxic heavy metal material, such as lead, mercury, cadmium, etc. So, choose the lithium battery of solar street light is a good choice.
