What are the advantages of lithium batteries for electric vehicles ? The following Dery Energy lithium battery manufacturers will explain to you:

The advantages of lithium batteries are as follows:

1. Under the same volume, the lithium battery can store more, which is conducive to reducing the weight of the body.

2. Lithium battery has no memory, and it is not easy to cause battery dead or life loss due to incomplete charging.

3. The lithium battery has a long life.

"Lithium battery" is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time. With the development of technology, lithium batteries have now become mainstream.

A lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the charging state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharged state, the main component of the positive and negative electrodes is lead sulfate. The nominal voltage of a single-cell lead-acid battery is 2.0V, which can be discharged to 1.5V and charged to 2.4V; in applications, 6 single-cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery. 24V, 36V, 48V, etc.

The weight of a lithium battery with the same capacity is only one-third of that of a lead-acid battery. The light weight will inevitably reduce the power consumption of the vehicle. Therefore, the cruising range of electric vehicles using lithium batteries will definitely exceed that of lead-acid batteries of the same capacity. At the same time, due to the reduction in the weight of the whole vehicle, the climbing ability and speed have also been greatly improved; and the life of lithium batteries is longer than that of lead-acid batteries, and the capacity drop is not as obvious as that of lead-acid batteries! Especially in winter, the capacity of lead-acid batteries decreases significantly, while lithium batteries do not change much.
