I. Cylindrical Cells Advantages And Disadvantages

1.Cylindrical lithium cells are easy to manufacture and mechanically stable, making them enduringly popular. They’re also very safe – if internal pressure grows too great, most cells are designed to rupture, mitigating safety hazards – and benefit from longevity, an attractive price point and comparatively low watt-per-hour cost, making them an economical choice.

2.The cylindrical design, however, causes notable space between cells, making space efficiency more challenging. A well-designed cylindrical-type lithium battery takes advantage of the structure’s energy-dense nature, using free space to install thermal regulation solutions.

3.Cylindrical cells are generally encapsulated in steel or aluminum shells, which are heavier and the energy density is relatively lower.

II. Prismatic Cells Advantages And Disadvantages

1.The shell of prismatic cell is mostly made of aluminum alloy, stainless steel and other materials. The weight of Prismatic cell is lighter than cylindrical cell. The winding or lamination process is used internally, and the protection of the battery cell is better than the polymer cell. And the safety of the prismatic cell has also been greatly improved compared with the cylindrical cell.

2. The prismatic cell is made of aluminum alloy, which is lighter and safer than steel shells cell.

3. Since the prismatic cell can be customized according to the size of the product, there are thousands of models on the market, and beause of there are too many models, the process is difficult to unify. The primastic cell has no problem in the use of ordinary electronic products, but for industrial equipment products that require multiple series and parallel connections, it is best to use a standardized cylindrical lithium cell, the production process can be guaranteed, and it will be easier to find replacement cells.

III. Polymer Cells Advantages And Disadvantages

1.The Polymer lithium cell’s key advantages lie in its thin profile, lightness and effective use of space; the Polymer cell’s thin, rectangular shape facilitates better layering and gives product designers increased flexibility. Unsurprisingly, polymer cells are typically found in mobile phones, tablets and other lightweight electronic devices.

2.While space efficiency makes polymer cells highly attractive, several disadvantages exist. polymer cells are expensive to design and manufacture, in turn making them more expensive for consumers. They die quicker, as thermal management is less effective, and are relatively sensitive to deformation in high-pressure situations, and easy leakage.

3.Other drawbacks include a limited number of standardized sizes and an average higher watt-per-hour price.
