Why are lithium batteries not replacing lead-acid batteries?

Lithium Iron Phosphate Batteries: An Alternative to Lead-Acid Car Batteries

Electric vehicle lithium battery is durable and has a long battery life. Why is there no replacement for lead-acid batteries?

Why Lithium battery no Alternative lead acid batteries

As one of the mainstream means of transportation, electric vehicles can be seen in cities or in rural areas, regardless of their economic ability, they may be Used, And They Can Be Easily Driven Regardless Of Age. Why Can Electric Vehicles Be So Popular?

Lead-acid battery electric vehicles are affordable

The price is close to the people, and everyone can afford it and use it. Electric vehicles are the most affordable vehicles to buy and use.

The more congested the road, the more prominent the advantages of lead-acid battery electric vehicles

With the improvement of the economic level of ordinary people, cheapness is no longer the only reference for deciding which means of transportation to buy. After all, the price of cars is also falling, and many people can afford cars. The popularity of cars has brought traffic congestion problems. As a two-wheeled means of transportation, the more congested the road, the more prominent the advantages of electric vehicles, and the more favored they are.

There are many kinds of batteries for electric vehicles, and lead-acid batteries and lithium batteries are the mainstream

As the most popular means of transportation at present, the technology of electric vehicles has reached new heights, and even many electric vehicles are comparable to motorcycles. Especially in terms of batteries, the technology is becoming more and more mature, and the types of batteries are becoming more and more abundant. At present, the batteries that have been used in electric vehicles include: “lead-acid batteries, lithium batteries, graphene batteries, colloidal batteries. Batteries, Ni-MH batteries, Zinc-air batteries” and so on.

However, although there are many kinds of batteries, the market share of lead-acid batteries and lithium batteries in the electric vehicles that are actually produced and sold exceeds 95%. Lead-acid batteries and lithium batteries are the mainstream, and lithium batteries are called electric vehicles. The best choice for car batteries, it has more advantages than lead-acid batteries.

Lithium batteries of electric vehicles are better than lead-acid batteries in many aspects

Lithium batteries are better than lead-acid batteries. Lithium batteries have been used in electric vehicles for many years. Through practice, lithium batteries are better than lead-acid batteries in at least the following aspects;

Long life (deep cycle)

As the core component of an electric vehicle, the durability of the battery is related to the life of the electric vehicle. A good quality lithium battery has a cycle life of about 800 to 2000 times, and a normal life of a lithium battery is 5 to 8 years. time, which is unmatched by the 3-year lifespan of lead-acid batteries.

The specific energy is large.

Many people do not understand this parameter, but the larger the specific energy, the higher the battery efficiency. The same battery capacity, their volume will be smaller. In practice, lithium batteries are indeed only lead-acid batteries in weight. One-sixth of the battery, and one-third of the lead-acid battery in volume.

It is a fact that the self-discharge rate is low,

and the battery life of lithium batteries is longer than that of lead-acid batteries. As we all know, even if electric vehicles are not used, the batteries will self-discharge. The reason is that the electricity is scrapped, and the self-discharge rate of the lithium battery is very low, so it can store more electricity, and the battery life is naturally stronger.

Lithium batteries for electric vehicles, why there is no replacement for lead-acid batteries

Lithium batteries have many advantages, and they are not only used in two-wheeled electric vehicles, but also in electric vehicles that require more battery life. At present, lithium batteries are the mainstream ones. Since lithium batteries have become mainstream batteries in electric vehicles, but Why have lithium batteries been “suppressed” by lead-acid batteries on two-wheeled electric vehicles, why are lithium batteries so easy to use, and why are there no substitutes for lead-acid batteries?

1. The price of lithium batteries is higher than that of lead-acid batteries. If you learn more about electric vehicles, you can find one thing in common, that is, lithium batteries are usually mounted on mid-to-high-end electric vehicles. It is more difficult, so its price will be much higher than that of lead-acid batteries, and the more expensive products will be more difficult to popularize, resulting in lithium batteries unable to replace lead-acid batteries.

2. Lithium batteries are not as safe as lead-acid batteries, and electric vehicles have the risk of spontaneous combustion. This is what we know from the news. Almost every month, we can see the spontaneous combustion incident of battery charging, and the spontaneous combustion incident has been investigated. , Electric vehicles are basically lithium batteries, because of the structure, lithium batteries do have the safety hazard of spontaneous combustion, but lead-acid batteries do not have this trouble.

3. Ordinary electric vehicles equipped with lead-acid batteries basically meet the demand. If a product is relatively expensive, even if it cannot completely monopolize the market, if the product is truly irreplaceable, it will become the mainstream, so why is lithium battery so far in share It is smaller than the lead-acid battery, which is mainly used as a two-wheeled electric vehicle, and has clear parameter requirements in terms of speed and battery life. Under this parameter setting, the more affordable lead-acid battery is enough to meet the demand.

Is it better to use lead-acid batteries or lithium batteries for electric vehicles?

Recommendation 1: Choose lead-acid batteries within 60 kilometers of battery life. As mentioned above, lithium batteries have the advantages of large specific energy and low self-discharge rate. If the battery life is too low, the advantages of lithium batteries cannot be highlighted at all. When using lead-acid batteries and lithium batteries, the difference is not too big, and the price of lithium batteries is three times that of lead-acid batteries, and lead-acid batteries can be recycled and reused. Therefore, when the battery life of electric vehicles is not high, lead is the first choice. acid battery.

Suggestion 2: Choose a lithium battery with a budget of more than 700USD. The budget determines the parameters of purchasing vehicles. For most people, electric vehicles within 2450USD are generally accepted. After all, they are only used for short-distance travel, and at this price, they will not buy To a very good lithium battery electric vehicle, with a budget of more than 700USD, you can choose an electric vehicle with good configuration in all aspects.

Conclusion: Lithium batteries have just been applied to electric vehicles. Experts inside and outside the industry believe that lithium batteries will be the future. However, from the current point of view, lithium batteries do not have such a development momentum. The product will definitely eliminate the former, but there are still differences between theory and practice, and the audience, consumption capacity, practical use and other aspects must be considered. It is unlikely that lithium batteries will completely replace lead-acid batteries in a short period of time. However, the market share of lithium batteries will become larger and larger.

Why Lithium Batteries Have Not Replaced Lead Acid Batteries Summary

Understanding AGM Batteries vs Deep Cycle Batteries

Among the deep cycle batteries, rechargeable lead-acid batteries come in many types and are often used to start the vehicle and operate as an engine, as well as for emergency lighting. AGM batteries have been around since the 1980s, and perhaps most people don’t know what AGM stands for. In this issue, we will discuss what is special about AGM batteries and how to use our AGM batteries reasonably!

What does DOD stand for in a battery?

As a battery pack that stores electricity, it can provide power sources for a variety of needs, including solar energy, wind energy, powered cars, ships, drones, etc. When we buy batteries from merchants, we often encounter 80% DOD or 100% DOD marks, so what effect does it have on the batteries we use?
