Lithium battery manufacturer: What are the obvious differences between soft battery and hard battery.

The biggest difference between soft battery and hard battery is similar to their names. The basic difference is that the packaging structure of a battery is soft and that of a battery is hard. The packaging technology of the flexible battery generally adopts the polymer shell, and the aluminum plastic film packaging is used in the structure; Hard coated batteries are generally packaged with steel or aluminum shells.

Hard packed batteries are divided into cylindrical and square ones. At present, most of the hard packed batteries on the market use square structures. Hard pack battery is better than soft pack battery in terms of airtightness due to different packaging technologies. However, the shape and structure of the flexible battery can be determined according to the customer's needs, so which type of battery to use depends on the environment.

Why don't electric vehicles use soft battery

Because of the special nature of the flexible battery, the manufacturing cost of the flexible battery will be relatively high, because basically the aluminum plastic film was originally imported; At the same time, the production efficiency of using soft battery will be relatively low, which greatly improves the production cost of electric vehicles; In addition, due to the structure, the structural tightness of the soft package battery is not as high as that of the hard package battery.

Therefore, the most important thing is that the production cost of the soft battery will increase a lot compared with the traditional hard battery. In addition, due to structural reasons, many car enterprises finally fail to consider the feasibility of the soft battery.
