SEM Morphology:
SEM imaging shows that S76L consists of single-crystal primary particles with clear faceted crystal surfaces and a uniform spherical to quasi-spherical morphology, consistent with the particle size distribution.

SEM, low magnification (×1,000, 50 μm scale bar).

SEM, high magnification (×2,000, 20 μm scale bar). Imaging with Hitachi SU8000 SEM.
XRD Pattern:
The XRD pattern shows a clean layered NCM structure with well-defined (003), (101), and (104) characteristic peaks and no secondary phases.

Electrochemical Performance (Coin Half-Cell, 4.30–3.0 V vs Li⁺/Li, 0.1C, 25°C):
| Parameter | Specification | Typical Value |
|---|---|---|
| Specific Capacity (mAh/g) | ≥ 172.0 | 176.3 |

Packaging & Storage:
S76L is packaged in aluminum-foil-laminated vacuum bags inside plastic drums or cartons, with a net weight of 20.00 kg ± 0.02 kg per drum. Alternative packaging such as ton bags or cartons can be arranged by agreement. When sealed under vacuum and stored in a cool, dry place, the shelf life is one year.
Handling Notes:
Avoid impact and inversion during transport
Store in a clean, ambient, cool and dry environment
Protect from direct sunlight, heat, and rain during transport
Use immediately after opening; if not used immediately, reseal to prevent moisture absorption
