The difference between lead-acid batteries and lithium batteries of electric bike
At present, the electric bike battery on the market are divided into two camps: lead-acid and lithium batteries, and for lead-acid batteries and lithium batteries, each has its own advantages, which brings certain difficulties to consumers in purchasing. Now, let’s take a look at the difference between these two electric batteries.
The difference between lead-acid batteries and lithium batteries:
1.Product price: The current mainstream lead-acid batteries on the market generally cost around RMB 450 , while lithium batteries are more expensive, usually around RMB 1,000 .
2.Service life: lead-acid batteries generally have a service life of about 2 years, while lithium batteries are more durable, with a life span of 4-5 years; lead-acid batteries are generally fully charged and discharged within 300 cycles, while lithium batteries are fully charged and discharged The number of cycles exceeds 500 times.
3.Mass and volume: With the same capacity, lead-acid batteries are heavier and larger than lithium batteries.
4.Electric battery capacity: Compared with lead-acid batteries, lithium batteries have a higher average voltage and higher energy density. In other words, a battery of the same size has a larger capacity.
5.Warranty period: The warranty period for lead-acid batteries is generally 1 year, while the warranty period for lithium batteries is longer, which can be guaranteed for 2 years.
Advantages and disadvantages of lead-acid batteries and lithium batteries:
1.Advantages of lead-acid batteries: Compared with lithium batteries, the price of lead-acid batteries is relatively cheaper, the recycling price is higher than that of lithium batteries, and the high-rate discharge performance is better.
2.Disadvantages of lead-acid batteries: lead-acid batteries are relatively heavier, and contain sulfuric acid and some heavy metal substances, which are corrosive and easily cause environmental pollution; in addition, lead-acid batteries have lower energy density, and their service life is less than that of lithium batteries.
3.Advantages of lithium batteries: Compared with lead-acid batteries, lithium batteries are smaller, lighter, more convenient to carry, and have a relatively longer lifespan. In addition, lithium batteries have greater energy, can provide greater current, and are more adaptable to high and low temperatures, are less affected by temperature, and are more environmentally friendly.
4.Disadvantages of lithium batteries: The safety and stability of lithium batteries are relatively poor. If they are not handled properly, there is a risk of explosion. In addition, lithium batteries cannot be discharged at high currents, and the production requirements are high, and the cost is also higher.
Which is better, lead-acid battery or lithium battery:
Lead-acid batteries and lithium batteries have their own advantages, so choosing the one that suits you is the best. Although lithium batteries have many advantages, at present, their technology is not perfect, and the initial products are often not mature. The lead-acid battery technology has become more mature and cheaper after years of precipitation. It is relatively better at present, and has always been favored by users.
However, lithium battery is the future trend of the battery industry, and the technology is also being improved step by step. After improving the cost performance, I believe that it can replace lead-acid batteries in the future.
