In the pursuit of higher energy density for lithium-ion batteries, silicon-based anodes have emerged as a promising candidate. However, their commercialization is hindered by challenges such as significant volume expansion and, critically, non-uniform lithiation. This article explores the causes, detrimental effects, and advanced solutions to mitigate this issue, a key consideration for anyon...

I. Structural Design of Power Battery Systems The structure of a power battery system comprises cells, modules, and battery packs. The cell is the most fundamental unit, and its structural design and material selection are decisive for battery performance. Mainstream cell types currently available include cylindrical, prismatic, and pouch cells, each offering certain advantages in terms of energy ...

The lithium battery separator acts as a protective barrier between the positive and negative electrodes, conducting ions but not electrons. In the ideal state after electrolyte filling and formation, the separator should maintain complete and flat contact with the electrodes. However, when we disassemble batteries, we often find severe wrinkling of the separator. (This can also be clearly observed...

As the global battery industry seeks alternatives to lithium-based chemistries, sodium-ion batteries have steadily moved from academic research into early-stage commercialization. Among various cathode candidates, NFPP (Na₃Fe₂(PO₄)₃) has gained increasing attention due to its balanced performance, structural stability, and supply-chain advantages. Rather than pursuing extreme energy density, NFPP ...

Formation and capacity grading are among the final and most critical stages in lithium-ion battery manufacturing. Although these steps occur after electrode fabrication and cell assembly, they strongly influence the electrochemical stability, safety performance, consistency, and lifetime of the final product. In industrial battery production lines, the formation process activates the battery for t...

Pouch cell batteries are widely used in consumer electronics, electric vehicles, and energy storage systems because of their high energy density, lightweight structure, and flexible design. Compared with cylindrical and prismatic cells, pouch cells use laminated aluminum laminated film as the outer packaging instead of a rigid metal case. This structure allows better space utilization and lower we...
