When designing lithium-ion batteries, the choice of battery casing material is critical. It must not only protect the battery's internal electrochemical components and structure but also possess properties like heat resistance, corrosion resistance, vibration resistance, and crush resistance. Among numerous materials, aluminum shells have emerged as the preferred choice due to their unique advanta...

Lithium-ion batteries (LIBs) are the powerhouse of modern electronics and electric vehicles (EVs), and their performance hinges on the cathode materials. Among these, ternary cathode materials such as NCM (Nickel-Cobalt-Manganese oxides) and NCA (Nickel-Cobalt-Aluminum oxides) dominate due to their balanced energy density and stability. However, varying the ratios of nickel (Ni...

The voltage of a lithium battery is closely related to the electrode potentials of its cathode and anode materials. Variations in voltage among lithium batteries using different materials primarily stem from the following factors: Impact of Electrode Materials’ Chemical Properties Lithium batteries operate through the movement of lithium ions between the cathode and anode during charging and disch...

In lithium-ion battery manufacturing, the fineness of the slurry (mainly referring to the electrode slurry) is a key parameter affecting electrode performance (such as capacity, rate capability, cycle life, safety) and process stability. Different battery types have significantly different fineness requirements for the slurry (usually measured by particle size distribution indicators such as D50, ...

Self-discharge in lithium-ion batteries refers to the phenomenon where the battery's charge/voltage naturally decreases when disconnected from an external circuit (i.e., in an open-circuit state). This is an inherent characteristic of all batteries, though the degree varies. Lithium-ion batteries exhibit a relatively low self-discharge rate but are still affected. The primary causes can be categor...
