The packaging technology of lithium batteries is simply the final appearance of lithium batteries. Mature lithium battery packaging technologies are three types: prismatic, cylindrical and pouch batteries.

　　In addition to the three mature packaging technologies, lithium batteries currently have new CTP technology, and have derived two new products, "blade battery" and "CTP battery", both of which are upgraded forms of prismatic batteries.

　　CTP (Cell to Pack) technology refers to the direct grouping of batteries, skipping the intermediate link of battery modules. On the one hand, this technology improves the space utilization rate in the battery pack and increases the charge capacity; on the other hand, it reduces the weight, which greatly increases the energy density of the entire battery pack.

　　At present, the blade battery represented by BYD chooses the solution of completely abolishing the module; the CTP battery of the CATL era is taking the route of integrating small modules into large modules.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　These two routes have their own advantages and disadvantages, but they are both in the early stages of commercialization, and the manufacturing process and mass production still need to be improved, and they cannot replace traditional technologies on a large scale in a short period of time.
