Under the dual pressures of energy shortage and global environmental protection, lithium batteries, with their high energy density and long cycle life, have become the core choice in the fields of energy storage and power. From power station energy storage systems, telecommunications and communication uninterruptible power supplies, to electric vehicles, military and aerospace equipment, the application scope of lithium batteries continues to expand.
In the composition of ternary lithium-ion batteries, the cathode material plays a decisive role in battery performance, and preparing high-quality ternary precursor powders is the key first step to obtain high-quality cathode materials. However, to accurately evaluate the quality and performance of ternary precursor powder, metallographic preparation is an indispensable key step. The following are the sample preparation method steps for your reference.
① P2500 metallographic sandpaper grinding
② CS + 3μm PD-WT diamond polishing solution polishing
③ ZN + 0.05μm AO-W alumina polishing solution polishing
