Why Are Lead-acid Batteries Not Being Replaced?

Many users who have bought electric vehicles know that there are various types of electric vehicle batteries. Whether it is a two-wheeled vehicle, a tricycle or a four-wheeled vehicle, different types of batteries can be installed, such as lead-acid batteries, lithium batteries, graphene batteries, etc.

Now, lithium batteries and graphene batteries have gradually occupied part of the market due to their advantages of long battery life, small size, and light weight. Will the traditional lead-acid batteries be replaced? In fact, in the long run, under the same volume, lithium batteries and graphene batteries with lighter weight, larger capacity, and more intelligent intelligence will have a larger market share, but lead-acid batteries still have their value.

1. Production technology of lead-acid batteries

First of all, in terms of production technology, lead-acid battery technology has been produced and used for decades. It is the battery category with the longest industrial production time and the most mature technology. Its performance stability and compatibility with electric vehicles All are higher. Moreover, the manufacturing cost of lead-acid batteries is the lowest among concentrated batteries, so its cost performance is also the highest among all batteries.

Although emerging batteries such as lithium batteries are popular in the market due to their long battery life, long life, and larger battery capacity, the current technology cannot guarantee that the battery will not fail during use. Once a problem occurs, other maintenance cost is too high, and the cost of using the battery will naturally come up.

2. The price advantage of lead-acid batteries

Lithium battery is a battery with relatively high power density. Although it is relatively small in size, it is expensive. In terms of our common 48V10Ah battery specification, the price of lithium battery packs is much higher than that of lead-acid batteries. Taking the price of electric vehicles as an example, lithium battery electric vehicles are more expensive than lead-acid battery electric vehicles. Therefore, more users are still willing to choose lower-priced lead-acid batteries.

3. Safety aspects of lead-acid batteries

The electrolyte characteristics of the lead-acid battery itself make the lead-acid battery non-flammable. In addition, the battery adopts normal pressure and low voltage design, and has good safety performance. Made into thousands of ampere-hour batteries, it provides convenience for large-scale energy storage. As for the characteristics of lithium batteries, because they store more energy after fully charged, lithium ions are too active, and they are easy to cause combustion due to extrusion, puncture, high temperature, etc. However, with the continuous advancement of technology, the performance of lithium batteries in the future will definitely tend to be stable.

If the lead-acid battery is in a state of incomplete discharge for a long time, it should be given a chance to fully discharge once a month to maintain the activity of the battery plate material. Complete discharge can run for a long distance until the controller is undervoltage protection and automatically cuts off. In general, lead-acid batteries still have great market advantages and will not be easily replaced in a short time.
