Is it better to use Rechargeable Cylindrical Pouch Battery or Rechargeable Square Pouch Battery for new energy vehicles?
A good electric car is definitely inseparable from a good battery, such as Rechargeable Cylindrical Pouch Battery, Rechargeable Square Pouch Battery and other types of batteries. For new energy vehicles, whether to choose a round battery or Rechargeable Square Pouch Battery is more practical More suitable? Let’s talk about it here. First, let’s talk about the basic characteristics of cylindrical lithium batteries. At present, the production process of cylindrical lithium batteries is mature, the cost is low, and the battery product yield and battery pack consistency are high because of the heat dissipation of the battery pack. With a large area, its heat dissipation performance is better than that of Rechargeable Square Pouch Battery; cylindrical batteries are easy to combine in multiple shapes and are suitable for full layout of electric vehicle space design, but cylindrical batteries are generally packaged in steel or aluminum shells, which are heavier , The specific energy is relatively low.
The rectangular hard-shell battery shells are mostly made of aluminum alloy, stainless steel and other materials. The coiled or laminated process is used inside. The safety of the battery core has also been greatly improved compared with the cylindrical battery. The steel shell of the cylindrical lithium battery In contrast, light weight and safety, as well as the resulting performance advantages, make aluminum shells the mainstream of lithium battery shells, and lithium battery aluminum shells are currently developing in the direction of high hardness and light weight technology.
Because Rechargeable Square Pouch Battery can be customized according to the size of the product, there are thousands of models on the market, and because there are too many models, the process is difficult to unify. Rechargeable Square Pouch Battery has no problem in use, and there is no clear standard division as cylindrical batteries, but for vehicles that require multiple series and parallel, it is best to use standardized production of cylindrical lithium batteries, so that the production process is guaranteed , It will be easier to find replaceable batteries in the future.
