Are lithium-ion batteries expensive? Which is more cost-effective, lithium-ion batteries or lead-acid batteries? The price of lithium-ion batteries is two to three times higher than that of lead-acid batteries. For long-term use, lithium-ion batteries are much more cost-effective. The development potential of lithium-ion batteries is higher than that of lead-acid batteries, and it is also very suitable as a power source for new energy vehicles.
Are lithium-ion batteries expensive?
Lithium-ion batteries are small in size, light in weight, fast in charging, long-lasting, and environmentally friendly new energy. The price of industrial lithium-ion batteries is around 2 yuan to 15 yuan, depending on the actual capacity and whether it has a protective board.
The production cost of lithium-ion batteries is high, the production equipment is expensive, and the labor cost accounts for about 40% of the production cost. The price is about three times that of lead-acid batteries.
The price of lithium-ion batteries is mainly related to their capacity, because the larger the capacity, the more electrical energy can be stored, for example, for electric vehicles, they can run farther. Therefore, we must first determine the specifications of lithium-ion batteries, including voltage, capacity and other parameters.
In terms of price, lithium-ion batteries are still twice as high as lead-acid batteries. The price of No. 5 rechargeable batteries is 89 yuan, and the price of AA1.5V lithium-ion batteries is 128 yuan. The performance is also very good. The price comes from the Internet and is for reference only.
Which one is more cost-effective, lithium-ion batteries or lead-acid batteries?
① Energy density
At present, the energy density of lead-acid batteries is about 50-70wh/g, while the energy density of lithium-ion batteries is generally 200-260wh/g, which means that when the battery weight is the same, the discharge efficiency of lithium-ion batteries is higher, and the battery life is also stronger.
② Number of cycles
Generally speaking, the more popular lithium-ion batteries at present are ternary lithium-ion batteries and iron-lithium-ion batteries. Generally speaking, the number of cycles of ternary lithium-ion batteries can reach more than 1,000 times, while the number of cycles of iron-lithium-ion batteries can reach 2,000 times. However, the number of cycles of lead-acid batteries is only about 300-350 times, so the service life of lithium-ion batteries is about 3-6 times that of lead-acid batteries.
③ Volume
The volume capacity density of lithium-ion batteries is usually about 1.5 times that of lead-acid batteries, so under the same capacity, the volume of lithium-ion batteries is about 30% smaller than that of lead-acid batteries.
④ Nominal voltage
The nominal voltage of lead-acid batteries is 2.0V, while the nominal voltage of lithium-ion batteries is 3.6V. Under the same voltage and current conditions, electric vehicles using lithium-ion batteries have more power and faster speed increases.
The price of lead-acid batteries is about 1/3 of that of lithium-ion batteries, which shows how low their price is. The performance of lithium batteries is so good, and the price is certainly not cheap, generally around 1,600 yuan per piece; while lead-acid batteries are of course cheaper, generally around 800 yuan per piece. Although the price of lithium batteries is twice that of lead-acid batteries, their service life is 5 times!
In general, due to the high endurance requirements, lithium-ion batteries shine in the field of new energy vehicle applications. The future development of new energy vehicles and the guidance of national policies will definitely promote the development of the lithium-ion battery industry.
