Advantages and disadvantages of lithium batteries and lead-acid batteries for solar street lights

<p>Solar street lights use clean energy and use battery panels to convert solar energy into light energy to provide lighting services. It is widely used in both urban and rural areas in my country. Not only street lights, but also garden lights, etc., all use solar power. The<a href="https://www.ufo-battery.com/lithium-battery-for-solar-street-light-lifepo4-battery-customized-battery" rel="noopener noreferrer" target="_blank"> lithium battery for solar street light</a> stores the electric energy of the solar panel and can be used for lighting at night.</p><p><br></p><p>As we all know, lithium batteries are widely used in today's society and are an advanced battery type. The main lithium battery used in solar lights is lithium iron phosphate energy storage battery. So, do energy-saving and clean solar lights use lifepo4 lithium battery?</p><p><br></p><p>In fact, there are lead-acid batteries in use at the same time. Compared with lithium iron phosphate battery, its disadvantages are:</p><p>1. Low energy density</p><p>The same is 48v12Ah, the lead-acid battery is only 33Wh, while the solar street lamp lithium battery can reach 125Wh</p><p>2. Service life</p><p>Lead-acid batteries have 60% capacity when cycled 300 times, while lifepo4 lithium battery&nbsp;still have 80% capacity when cycled 1500 times</p><p>3. Not environmentally friendly</p><p>Lead-acid batteries produce pollution, and lithium batteries are recognized as environmentally friendly batteries.</p><p><br></p><p>Since there are so many shortcomings, why are lead-acid batteries still in widespread use? Mainly because of its mature product, low price and convenient maintenance. So it is still the mainstream of the market.</p><p><br></p><p>But with the restrictions of national industrial policies, market share is declining. The market share of solar light lithium batteries is gradually increasing, and the prospects are broad.</p>
