Solar street lamps use clean energy and use panels to convert solar energy into light energy to provide lighting services. It is widely used in both urban and rural areas of our country. Not only street lights, but also garden lights, etc., are powered by solar power.
Solar street lamp lithium batteries store the energy of solar panels and light them at night. As we all know, lithium batteries are widely used in today's society and are an advanced type of battery. Solar light lithium batteries are mainly lithium phosphate energy storage batteries.
So energy-saving, clean solar lamps, are they using lithium iron phosphate? There are lead-acid batteries in use at the same time.
Compared to lithium iron phosphate batteries, its disadvantages are:
1, Low energy density
The same is 12V 10Ah, the lead-acid battery is the only 80Wh, and the solar street lamp lithium battery can reach 128Wh
2, Service life
Lead-acid batteries have 60% capacity at 300 cycles, while lithium iron phosphate batteries still have 80% capacity when cycled 3000 times
3, Not environmentally friendly
Lead-acid batteries are contaminated, and lithium batteries are recognized as environmentally friendly batteries. With so many shortcomings, why are lead-acid batteries still widely used? Mainly because its products are mature, cheap, easy to repair.
So it's still the mainstream of the market. But with the limits of national industrial policies, market share is declining. Solar lamp lithium battery market share, is gradually rising, broad prospects.
