The method of increasing the battery capacity is a conscientious approach. There are many ways to increase the capacity, the most of which is to start with the battery material. At present, ternary lithium-ion batteries are the highest proportion of power lithium battery types in China, and the proportion of lithium iron phosphate batteries has fallen very quickly. However, no matter how conscientious it is, it won't do anything good if it falls into the hands of the wrongdoer. In order to increase the battery capacity, some manufacturers have lowered the requirements for battery stability, and the safety hazards have increased. Therefore, some people in the industry worry that the rapid success in battery capacity may affect the safety of electric vehicles.

Another way is to reduce the overall weight of the entire power lithium battery, which is actually a temporary solution rather than a permanent cure. Some high-quality power lithium batteries have a separate cell for each battery pack, so that the entire battery pack will not be affected in the event of a failure. To reduce the weight of power lithium batteries, these cells are the first to bear the brunt. Either develop new materials to reduce weight without affecting the protection of the battery, or directly reduce the material or replace it with a lighter but weaker material.
