Why are lithium-ion batteries divided into hard packs and soft packs? The characteristics of hard-packed lithium-ion batteries. Power lithium-ion batteries are divided into soft packs and hard packs, and hard packs are divided into cylinders and squares. The packaging structure has advantages and disadvantages. In terms of market trends, the share of soft pack batteries is increasing and is estimated to exceed 50%. Car manufacturers want powerful lithium batteries, and they don’t know the battery pack. It is best to communicate with the lithium battery manufacturer. The overall goal is to promote soft batteries.

Why are lithium-ion batteries divided into hard packs and soft packs?

Lithium-ion batteries are divided into two important types: soft case and hard case. One reason is to meet the special requirements of lithium-ion batteries in different application environments, and the other reason is the higher energy ratio.

High energy ratio is an important indicator of all batteries. The low weight of soft lithium-ion batteries may allow the device to insert heavier soft lithium-ion batteries.

If you want to choose a lithium-ion battery, you can’t choose between a hard case and a soft case. If you don’t know which one is better, you can go back and think about what you want to satisfy when you buy a lithium-ion battery. According to your needs, which battery is better depends on your needs.

From the perspective of the packaging process, lithium-ion batteries are divided into two types: soft pack and hard pack. The packaging process of soft-packed lithium-ion batteries is different from that of hard-packed lithium-ion batteries, and it must meet the energy ratio requirements.

Characteristics of hard-packed lithium-ion batteries

Lithium-ion batteries in rigid packaging: There are two types of classification: cylindrical and square. The packaging structure has its advantages and disadvantages, the important thing is that it should be related to different demand points. It is difficult to guarantee the consistency of tightly packed lithium-ion batteries. There are too many models and it is difficult to standardize the craftsmanship. It is suitable for custom processing and is not convenient for automatic processing of lithium-ion battery packs.

The hard-shell lithium-ion battery pack and the soft-shell lithium-ion battery pack are mainly related to the packaging materials of the lithium-ion battery pack. If there is wrapping paper on the outside, it is not easy to see. You need to see the main body of the battery. The weight of a steel shell battery will be heavier than a battery of the same volume. However, the key point of the battery is that it is not easy to distinguish between an aluminum case and a soft-shell battery, but the soft-shell battery is slightly softer than an aluminum battery and is easily deformed by breaking it by hand.

Lithium-ion batteries are currently undergoing a period of rapid product development. The market share of flexible lithium-ion batteries is still high and the largest. In addition, the biggest difference between soft lithium-ion batteries and other batteries is that the soft packaging material uses aluminum. Plastic composite membrane, which is also the most important and technically demanding material in soft lithium-ion batteries.
