1. Lithium batteries are better. Regardless of the volume or weight specific energy of lithium batteries, lithium batteries are more than three times superior to lead-acid batteries. Lithium batteries are smaller and lighter. Long life expectancy. The lifespan of lithium batteries used in electric vehicles is typically more than 800 times longer. Lithium batteries using lithium iron phosphate cathode materials can reach about 2,000 times, which is 1.5-5 times longer than lead-acid batteries. This significantly reduces the cost of using lithium batteries, extends their service life and improves the convenience of use.
2. Comparison between lithium batteries and lead acid batteries
1 Battery capacity
The capacity of lithium batteries is generally 8-10A, and that of. lead acid batteries The capacity is about 20A.
2. In terms of kilometers traveled
It is also a 48V battery when fully charged, lithium battery and lead acid battery electric vehicles can travel 30-40 kilometers. its speed depends mainly on the size of the motor used.
3. In terms of durability
Lithium batteries have strong durability, slow consumption, can be charged and discharged more than 500 times, and have no memory. 5 years. Lead-acid batteries generally have a memory of less than 400 deep charges and discharges and have a lifespan of approximately two years. If you are using a maintenance-free lead-acid battery, be aware that the battery loses little water and it is usually not necessary to add distilled water when using it. In terms of durability, lithium batteries have good vibration resistance. The fully charged battery is securely attached and vibrates atan amplitude of 4 mm and at a frequency of 16.7 Hz for 1 hour. There are no leaks, no battery expansion or rupture, or opening. the circuit voltage is normal; good recharge capacity, 0.1AC fully charged battery at 25 degrees Celsius for 48 hours, no leakage, no battery expansion or rupture, normal open circuit voltage, capacity retention rate above 95%, good toughness acquainted significantly, entirely; charged battery When the battery is discharged for 5 minutes at 2AC or 5 seconds at 10AC, no conductive parts will merge and there will be no appearance deformation.
4. In terms of price and warranty period
The current consumer battery is 48 volts. If it needs to be replaced, the lead-acid battery costs about 380-450 yuan (.48V12AH-48V20AH). The warranty period is 1 year; lithium batteries are relatively expensive, costing around 1,000 yuans (48V12AH), but the warranty period is 2 years.
5. Warranty period
The common battery on the market is 48 volts. If it needs to be replaced, the lead-acid battery is about 450 and the warranty period is 1. year; lithium battery price It is relatively expensive, costing about 1,000 yuan, but its warranty period is 2 years.
Which is better, lead acid battery or lithium battery?
The difference between lithium battery and lead acid battery is as follows : different weight, different lifespan, and different battery capacity.
1. The weight is different. The weight of the lithium battery is only 1/4 of that of the lead-acid battery of the same capacity, and the volume is only 1/3 of that of the lead-acid battery. lead acid battery of the same capacity.
2. The lifespan is different. The lifespan of lead-acid batteries is generally enaround 2 years, while lithium batteries are more durable, with a lifespan of 4 to 5 years. The lead-acid battery cycle is generally fully charged in 300 times, while the lithium battery is fully charged and discharged more than 500 times.
3. Battery capacity is different from lead-acid batteries, lithium batteries have higher average operating voltage and higher specific energy. In other words, for the same size rechargeable batteries, lithium batteries. have greater capacity.
Applications of lithium batteries:
Lithium batteries are widely used in energy storage systems such as hydropower, l thermal energy, wind energy and solar power plants. , and uninterrupted postal and telecommunications communications Power supplies, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.
Lithium-ion batteries have been widely used in portable devices such as laptops, cameras and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery has been tested in electric vehicles and has become one of the main power sources for electric vehicles in the 21st century. It will also be used in satellites, aerospace and energy storage.
With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of lithium battery industry.
On the mCurrent market, lead-acid batteries and lithium batteries have always occupied a dominant position. Lead-acid batteries and lithium batteries have their own advantages. Lead acid batteries and lithium batteries? Which battery is best? Today the editor will analyze it for everyone.
Which is better, a lead acid battery or a lithium battery?
1. Lifespan: Lead-acid batteries can generally be charged about 400 times and have a short lifespan. , generally 2 years. Lithium batteries are much more durable than lead acid batteries. Due to their low consumption, lithium batteries can be charged more than 500 times and have a lifespan of 4 to 5 years.
2. Volume and quality: In terms of volume, lead acid batteries are bulky while lithium batteries are smaller, so lithium batteries are more convenient for drivingand transportation. From a quality perspective, both have their advantages and disadvantages, and consumers can choose according to their own circumstances. Here I would like to remind everyone to choose top brands when purchasing.
3. Price and warranty: The replacement price of lead-acid batteries on the market today is relatively cheap, about 500 yuan, and the warranty is generally one year, while the replacement price of lithium batteries is generally 5,000 yuan. twice that of lead-acid batteries, reaching It costs around 1,000 yuan, but comes with a 2-year warranty.
4. Miles traveled: If the batteries are of the same power and both are in sufficient power state, the miles traveled of lead-acid batteries and lithium batteries are almost the same, mainly depending on the engine power.
5. Capacity: the capacity tothe lead-acid battery is relatively large, reaching 20 amps; The capacity of the lithium battery is relatively small, only 8-10 amps.
6. Environmental protection: From the perspective of environmental protection, although lead-acid batteries have gradually begun to follow the path of green production, we generally still cause environmental pollution if we use incorrectly lead-acid batteries. The production process of lithium batteries has always been green and environmentally friendly, and it is also more environmentally friendly in terms of recycling and use. Therefore, from the perspective of environmental protection, lithium batteries are truly environmentally friendly products.
