In the solar street light battery market, lithium battery is a super energy-saving de Nova products, with its safety, light weight, long service life, complete charge and discharge, low maintenance costs, no memory effect and other characteristics of the rapid occupation of the market. Lithium batteries are also divided into ternary lithium batteries, lithium iron phosphate batteries, lithium iron manganate batteries and other types.
Solar street light lithium battery relative to the traditional lead-acid battery. Lithium batteries have no pollution is certain, long life, no memory effect, charge and discharge more times, thus longer life and other characteristics. For example, the same capacity of lead-acid batteries and lithium battery comparison, lead-acid battery charge and discharge times of 400 times, while lithium batteries can reach about 1000 times, is nearly three times the lead-acid battery, and thus the life of the lead-acid battery is nearly three times. At present, energy storage lithium batteries are widely used in the solar street light market, but due to the problem of market confusion, some consumers often buy poor quality lithium batteries, so how to judge the quality of solar street light lithium batteries?
Lithium battery how to detect.
1, shape testing: variable width, thickness, TTV, verticality, warpage and chamfering.
2, electrical performance testing, including the type of conductivity, resistivity and less son life.
3、Appearance inspection: hidden crack (infrared flaw detection), cracks, perforations, microcrystals, line marks, crystal off, chipped edges and missing corners.
4, impurity analysis: impurity oxygen, carbon content analysis.
In addition, if we do not have professional tools to determine the good or bad lithium battery, then it is recommended to look at the appearance of the product, if the appearance is older, then this is not a good quality product, so the purchase of products to see the brand of lithium battery products.
The advantages of lithium batteries.
1, lithium battery voltage is high and light weight. A single battery can reach an average voltage of 3.7V or 3.2V. Relatively equal to 2-4 NiMH or Ni-isolated batteries in series voltage.
2, the energy and density of lithium batteries for other batteries is also very high. Lithium batteries have high storage energy density, currently commonly used lithium battery density can reach 450-620Wh/kg, is 5-7 times more than lead-acid batteries. If people choose the battery will also take into account a very important issue, that is, pollution.
3, for the battery weight to compare. The weight of a lithium battery is about 5-6 times that of a lead-acid battery. Although the weight of lithium batteries and lithium polymer batteries is not much difference in weight. But look at the capacity and life, people are going to choose the lithium battery.
4, lithium battery life time life is very long, a lithium battery life if no accidents can be used for more than 6 years, up to 9 years. The normal number of uses is more than 1000 times. If no accident occurs the number of times used can reach more than 1500 times.
5, low self-discharge, and no memory effect. The production of lithium batteries to the body of the lithium battery to add a protection plate can make the lithium battery has an overcharge and overdischarge effect. The lithium battery itself has a high power tolerance.
6, lithium battery green, lithium batteries do not contain lead, mercury, cadmium toxic substances.
