Due to the huge demand in the market, in recent years, major electric vehicle companies have been deeply cultivating technology. Taking the battery, one of the most important components, as an example, from the initial lead-acid battery to the graphene battery and lithium battery that gradually occupy a large share. The types of batteries on electric vehicles are becoming more and more abundant. However, so far, lead-acid batteries have not been replaced by lithium batteries with better performance. Why?

From a long-term perspective, under the same volume, lithium batteries are lighter and have better battery life; compared with traditional lead-acid batteries, graphene batteries have better service life, charging time, and battery life performance. There are better alternatives, why have lead-acid batteries not been replaced?

Reason one: mature technology cost-effective

From the perspective of production technology alone, lead-acid batteries have been in the market for decades. They are battery brands with mature technology and stable performance, and have a high degree of adaptation to electric vehicles. As for the manufacturing cost, the advantages of lead-acid batteries are more obvious. In other words, lead-acid batteries are more cost-effective in all battery categories. Considering the cost of production and manufacturing, the value of lead-acid batteries is self-evident.

Reason two: high safety performance

The characteristics of lead-acid batteries make them non-flammable, and the batteries are designed with normal pressure and low pressure. Even if they are overcharged and overdischarged, safety problems will rarely occur, and it is more reassuring for car owners to use them.

However, due to the high energy storage of lithium batteries after full charge, it is easy to cause safety hazards under the conditions of extrusion, puncture or high temperature, and it is not as good as lead-acid batteries in terms of safety performance. However, as the technology matures, it is believed that the performance of lithium batteries will stabilize.

Reason three: the price is cheap

The price here is cheap from the perspective of consumers. Although lithium batteries are small in size and large in capacity, the corresponding manufacturing cost is high, so the price is much higher than that of lead-acid batteries. The price of electric vehicles equipped with lithium batteries is usually thousands of yuan more expensive than electric vehicles equipped with lead-acid batteries.

If the user only plans to buy a transportation tool and does not have too high requirements for all aspects of the performance of the electric vehicle, he will naturally choose an affordable lead-acid battery. Or ordinary electric vehicles equipped with lead-acid batteries, in fact, can meet the daily travel needs.

How to choose lead-acid batteries and lithium batteries?

If you are entangled in how to choose lead-acid batteries and lithium batteries, it is recommended to choose lead-acid batteries within 60-70 kilometers, because if the cruising range is too short, choosing lithium batteries is somewhat "overqualified"; if the budget is sufficient and the electric vehicle has a range If mileage is required, electric vehicles equipped with lithium batteries can be selected.

Key words:

Clearly lithium batteries are more durable and have a long life, why can't they replace lead-acid batteries?

Lithium batteries have many advantages. Why don't manufacturers replace all electric vehicle batteries with lithium batteries?

Electric car battery, lead acid and lithium battery how to choose? which batteries to avoid
