Knowledge introduction of lithium-ion batteries and lead-acid batteries for solar lights

Solar lights, lithium-ion batteries and lead-acid batteries, solar street lights use clean energy and convert solar energy into light energy to provide lighting services. It is widely used in my country's urban and rural areas. Not only street lights, but also garden lights, all use solar energy to generate electricity. Lithium-ion batteries in solar street lights store electricity from solar panels and light them at night. As we all know, lithium-ion batteries are widely used in today's society and are an advanced battery type. Lithium-ion batteries for solar lights mainly use lithium iron phosphate energy storage batteries. So, do energy-saving and clean solar lights use lithium iron phosphate batteries? In fact, lead-acid batteries are also in use. Compared with lithium iron phosphate batteries, it has the following shortcomings: 1. Low energy density is also 48v12Ah, lead-acid battery is only 33Wh, while solar lamp lithium-ion battery can reach 125Wh 2. Service life lead-acid battery capacity is 60 at 300 cycles %, while the capacity of the lithium iron phosphate battery is still 80% after 1500 cycles. 3. It is not the pollution caused by the green lead-acid battery, and the lithium ion battery is considered to be an environmentally friendly battery. With these shortcomings, why are lead-acid batteries still in widespread use? The important reason is that their products are mature, inexpensive, and easy to maintain. So it is still mainstream. However, due to my country's industrial policy restrictions, the market share is declining. The market share of lithium-ion batteries for solar lamps is gradually increasing, and the prospects are broad.
