Lead Acid Battery vs Lithium Ion

The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, their ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by starter motors. Now lead acid batteries are commonly found in many applications, including UPS systems, automobile starting, lighting, and ignition (sealed lead acid battery), and even off-grid power systems. Lead acid battery vs lithium ion battery: there’re differences. 

A lithium-ion battery or Li-ion battery is a type of rechargeable battery composed of cells in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging. Li-ion cells use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode. Li-ion batteries have a high energy density, no memory effect (other than LFP cells) and low self-discharge. Cells can be manufactured to prioritize either energy or power density. They can however be a safety hazard since they contain flammable electrolytes and if damaged or incorrectly charged can lead to explosions and fires. Lithium ion batteries are always used for electronic appliances and portable applications.

FAQ for Lead Acid Battery vs Lithium Ion

  • Are there any benefits to lead acid battery or lithium ion?
  • Both lithium ion battery and lead acid battery do well in different applications. Lithium ion batteries are much lighter than lead acid ones when in the same capacity, which makes it easy to use lithium ion batteries in portable applications. Also, lithium ion batteries work well in efficiency and lifespan than lead acid batteries. However, lead acid batteries are more budget-friendly.
  • Lead-acid vs lithium ion batteries: Which are best for solar?
  • Lead-Acid batteries and lithium batteries are both commonly found in solar. But lithium batteries actually perform well when used in solar due to their high efficiency and long battery lifespan. What’s more, lithium batteries are low maintenance and exempt from scheduled cycling.
  • Do lithium batteries refill faster than lead-acid batteries?
  • Compared to lead-acid batteries, lithium ion batteries enjoy higher efficiency, thus comes a faster charge rate. Lithium ion batteries can also handle a high amperage from the charger, while lead-acid ones do not. So Lithium ion batteries refill faster than lead-acid batteries.
  • Why is traditional lead acid being replaced with lithium ion?
  • With the great development of lithium technology, lithium batteries have replaced lead acid batteries in many applications. There’s difference between lead acid battery and lithium ion battery. Compared with lead acid batteries, lithium batteries both are efficient and lightweight due to their high energy density, thus they’re usually found in portable applications. Despite being more expensive than normal batteries, lithium batteries offer a longer battery lifespan.
  • What is the recycling method for lithium ion batteries and how environmentally friendly is it vs. lead acid?
  • Currently, most lithium ion batteries need to be shredded into very small pieces by shredders, thus to be recycled. After shredding, the very small pieces, also called “black mass,” can extract cobalt, nickel and other valuable metals. The recycling methods of Lead acid battery vs lithium ion battery, there are differences. Lead acid batteries are highly recycled today, with a 90% recycling rate in many countries. Compared to the recycling process of lithium ion batteries, it’s more rigorous to recycle a lead acid battery, as it needs to be separated into pieces, then the sulphuric acid inside is neutralized and turned into sodium sulfate, and the lead and polypropylene parts are recycled to be used in other applications.
