I believe that the battery industry has a certain understanding of friends, lithium batteries and lead-acid batteries will not be unfamiliar with the rapid popularity of the new energy industry, new energy vehicle power battery often used battery type: lithium batteries and lead-acid batteries. For lithium-ion batteries and lead-acid battery difference: battery materials, battery cost, charging range. Lithium-ion batteries have high energy, and its charging speed is faster, its cost is higher, lead-acid batteries are relatively cost-effective.
1. Battery materials and capacity:
Positive and negative lithium battery materials are often used for lithium metal or lithium alloy, positive materials often used materials: cobalt, lithium iron, ternary and other materials. Negative electrode is mostly graphite powder or artificial graphite. The electrolyte is often a non-hydrolysable solution. Lead-acid batteries often use lead, other oxides, the electrolyte used is: sulfuric acid solution. Therefore, the capacity also has a difference, lithium battery capacity is often: 8-10A, lead-acid battery capacity is often: 18-20A.
2. Battery price:
Lithium batteries are mainly made of electrode materials, electrolyte, diaphragm and other combinations. Therefore, lithium batteries for lead-acid batteries cost more, so the price, lithium batteries than lead-acid batteries price is a little higher.
3. Battery charging:
Lithium battery charging time is relatively fast, only a few minutes to 3 hours. And lead-acid battery charging even reached 10 hours. Mainly because lithium-ion batteries can receive current quickly, so lead-acid batteries are faster.
