The structure of prismatic cells:
The main components of a typical prismatic cell include top cover, shell, positive plate, negative plate, diaphragm consisting of laminated or wound, insulation parts, safety components, etc.
The shell of the prismatic cell is generally steel or aluminum; with the market-driven pursuit of energy density and the progress of production processes, the aluminum shell is gradually becoming mainstream.
What are the advantages and disadvantages of lithium prismatic cells?
Advantages
The prismatic cell has the high reliability of the package; it has high energy efficiency, is lightweight, has high energy density, has a simple structure, and is easy to expand. It is currently an important option to increase the energy density by increasing the capacity of a single cell;
Disadvantages
People can customize the prismatic cell according to the size of the product, so there are thousands of models on the market. The processes are difficult to standardize, the level of production automation is not high, the variability of the single unit is significant, and in large-scale applications, there is a problem that the system life is much lower than the life of the single cell.
