Lithium battery:
1: (light, small size) Lithium battery developed since childhood
Lead acid battery with the same capacity on the market In comparison, the volume of lithium battery is 2/3 of the volume of lead-acid battery, and the weight is about 1/3 of the weight of lead-acid battery. Lithium batteries of the same volume have a higher capacity than lead acid batteries. Reducing weight increases the range of electric vehicles by approximately 1
0%.
2: (Increased lifespan) Lithium batteries are well known for their health. The average lifespan of lithium batteries is about one year, about 1.5 times longer than lead-acid batteries. charged and discharged more than 500 times, and the battery will last forever. Memory, strong resistance to earthquakes.
3: (Resistance to overload, good(resistance to charge and discharge) Lithium batteries have opened the eight extra meridians since childhood, so at normal temperatures, lithium batteries can be continuously charged for 48 hours without a battery. Expansion and leakage In case of accidents such as liquid rupture, the capacity remains above 95%. And with a special charger, it can be charged and discharged quickly.
The production cost of lithium batteries is high, and the production equipment is expensive and labor costs account for
about 40% of the production cost . The price is about three times that of lithium batteries. lead-acid batteries. At three times the price, the quality/price ratio is not very high. It looks rather flashy and the lithium battery is not recyclable. Once worn out, you can only throw it away or find a place to bury it. After thousands of years, generations wereures will dig it up and it will be an antique.
Can lead-acid batteries and lithium batteries for electric vehicles be used interchangeably?

Are lead acid batteries better than lithium batteries? In fact, there is no essential difference between theux in principle. This mainly lies in materials, mainly reflected in electrode materials and electrolytic materials. So there will be a big difference between the two in daily applications. both are reflected in usage in terms of lifespan, endurance and environmental impact.
The reasons why lithium batteries are better than lead acid batteries:
1. Lifespan
The first is the lifespan of lithium batteries which are very safe. and are used in acupuncture, they are always safe and will not deform under harsh conditions such as short circuit and extrusion. Good temperature performance, can be used at high temperatures without affecting service life. Lithium batteries therefore have a longer lifespan than lead acid batteries.
2. Endurance
The biggest problem with lead acid batteries is theeur high energy density. Conventional lead-acid batteries generally weigh more than 35 kilograms, which will affect battery life and machine mobility. Lithium batteries of the same capacity generally weigh less than 10 kg and are half the volume of lead-acid batteries. Additionally, lithium batteries charge quickly, while lead-acid batteries charge slowly and consume power quickly.
3. Environmental impact
Lithium batteries are cleaner and more environmentally friendly than lead acid batteries. As we all know, lead is a heavy metal and therefore lead batteries can have a significant impact on the environment. However, lithium batteries do not cause any environmental pollution either during their production or during their use.
In summary, lithium batteries are superior to acid batterieslead in terms of lifespan, endurance and environmental impact.
What is the difference between lead acid batteries and lithium batteries?
Battery life is different, market price is different, mileage is different, volume, quality and driving. the kilometers are also different.
Battery life; Lead-acid batteries typically have a lifespan of around 2 years, while lithium batteries are more durable, with a lifespan of 4 to 5 years. Lead-acid batteries are typically fully charged and discharged in 300 cycles, while lithium batteries are fully charged and discharged in over 500 cycles.
Market price: Currently, the most common lead-acid battery on the market costs about 450 yuan, while the price of lithium battery is about 1,000 yuan.
Mileage: The battery is also48 V. When fully charged, lead-acid/lithium battery electric vehicles have similar ranges, depending on vehicle speed, engine size, etc.white. Of course, in terms of battery capacity, lead-acid batteries are slightly larger than lithium batteries.
Quality: Compared to the lightweight body with a lithium battery of only 2.5/3 kg, the lead-acid battery with the same capacity generally weighs around 16/30 kg. Not only is the battery high quality, but it is also high quality. also large in size compared to lead acid battery. Compared with cars, lithium-ion cars adopt a detachable design, which is more convenient to drive and carry.
Mileage traveled: The same battery is 48V. Once fully charged, electric vehicles equipped with lead-acid batteries and lithium batteries can travel30 to 40 kilometers. The speed mainly depends on the size of the motor used. Are lead acid batteries better than lithium batteries? What is the difference between lead acid batteries and lithium batteries @2019
Yes, both lead acid batteries and lithium batteries are energy sources. voltage and current to motors and other circuits. As long as the battery voltage is the same, it can be used universally.
Lithium batteries have the advantages of extremely low self-discharge rate and gentle discharge voltage, allowing pacemakers implanted in the human body to work for a long time without recharging. Lithium batteries typically have a voltage rating above 3.0 volts and are best suited for use as an integrated circuit power supply.
Charging involves connecting an external DC power supply tothe battery to charge it, so that electrical energy is converted into chemical energy and stored. Discharging is the release of electrical energy from the battery to power external devices.
When the VRLA battery charge reaches its peak, the charging current is only used to break down the water in the electrolyte. At this time, the positive electrode of the battery produces oxygen and the negative electrode produces hydrogen. . The gas will overflow the battery, causing electrolysis. The liquid is reduced and water must be added from time to time.
Detailed information:
When charging lithium batteries, the upper limit of voltage must be adjusted Only then can the lifespan, capacity and safety of the battery be taken into account at the same time. The ideal upper limit of the charging voltage is 4.2 V. The batteriesLithium batteries must also have a lower voltage limit when discharging. When the cell voltage is lower than 2.4 V, some materials begin to be destroyed. And since the battery will self-discharge, the longer it is discharged, the lower the voltage will be. So it is better not to stop the discharge at 2.4 V.
When a lithium battery is discharged from 3.0 V to 2.4 V, the energy released is only approximately 3% of battery capacity. Therefore, 3.0 V is an ideal discharge cut-off voltage.
When charging and discharging, in addition to voltage limitations, current limitations are also necessary. When the current is too high, the lithium ions do not have time to penetrate the storage location and will accumulate on the surface of the material.
