Square battery and soft bag lithium battery.powerstation lifepo4

　　Generally speaking, a square or rectangular battery is called a square battery. The most common is the mobile phone battery. Most of the encapsulated shells are mostly used in aluminum alloy and stainless steel. The soft bag lithium battery is a liquid lithium -lyric battery cover on the upper layer of polymer shell. The structure is used in the structure. When the hidden safety hazard occurs, the soft -packed battery will only spit up and the safety is very high.

　　Founded battery advantages and disadvantages

　　1. Advantages

　　The packaging shells of square batteries are mostly materials such as aluminum alloy and stainless steel. The internal battery is used for rolling or overlap type. The shape battery has also improved greatly.

　　2. Disadvantages

　　Because the square battery pack can be customized according to the size of the product, it will also cause many square batteries on the market. Too many different types of batteries will make it difficult to unify the process, make the automation level is not high, the single difference is large, and there may be a set of square battery packs in the group.

　　Soft bag lithium battery advantages and disadvantages

　　1. Advantages

　　Soft bag lithium batteries use polymer electrolytes and soft packaging materials. This is the most critical and most technical difficulty in soft -pack lithium batteries. Soft packaging materials means that the soft bag lithium battery can also be customized according to the requirements of the customer's requirements. The soft -bag lithium battery does not explode like a square lithium battery and cylindrical lithium battery, and the weight is lighter than other batteries.

　　2. Disadvantages

　　Although the shape of a soft -pack lithium battery can be customized according to the needs of customers, the existing soft -packed electrical core numbers are small, which cannot meet the needs of the market, and the cost of developing new models is relatively high. In addition to the high development cost, the cost of the soft -packed lithium batteries is higher than that of squares. The cost problem is the focus of the breakthrough of soft -pack lithium battery companies in the future.
