he development concept of large cylindrical battery revolves around three aspects: high safety, long life, and high rate is designed for small power batteries. Our 4680 battery, from the perspective of safety life, is also standardized. Now the battery is roughly the same size as other general batteries on the market, and can be assembled in existing products at will. In addition, we have developed a large cylindrical 46120 with full-ear ears for high-rate needs. Whether it is cycle life or safety, we have achieved a relatively high level.
From our current point of view, we have done some tests, whether it is safety or reliability tests, our performance is particularly excellent, especially in safety, such as crashes, fires and other demanding tests, we can now pass.
To sum up our large cylindrical sodium battery, there are three main points. The first is extreme safety. The NFPP system we use is a very high-safety system. The second performance, whether it is low-temperature discharge, rate performance or cycle performance, is relatively comprehensive. Another one is cost, which was mentioned before. Including our structural parts design and so on, we have carried out comprehensive work around these three aspects.
