In the same energy consumption, the battery pack volume and weight of the same situation, new energy vehicles single maximum driving range depends on the energy density of the battery. The higher the energy density of a battery, the more power it can store per unit volume or weight.
However, high energy density is only one of the indicators for evaluating a battery, which should be measured from the three dimensions of energy density, life and economy. From the history of lithium-ion batteries, the first to be eliminated is the highest energy density lithium cobalt acid battery. Because although the energy density of lithium cobalt acid is high, but the safety is not guaranteed.
Therefore, although the benefits of high energy density are obvious, such as the same amount of power battery volume and weight is lighter, then you can leave more buffer space for collision. It can also greatly reduce the weight of the vehicle, reducing energy consumption. The same weight, you can carry more batteries, you can have a longer range. But it also has to be based on the premise of increasing safety and cycle life.
