·Single-particle mechanics and electron transport performance are the core elements to improve battery performance. The single-particle compressive strength directly affects the powder compaction density and the optimization of the electrode rolling process. The single-particle electronic conductivity ensures efficient electron transmission of the electrode by reducing internal resistance, enhancing charge and discharge rate performance, and inhibiting the degradation of contact resistance during the cycle.
Test method: The microsphere particles are dispersed with a solvent and placed on a stage, and a compression test is performed using a test system, and then observed under an optical microscope;

1. Silicon Carbon-Single Particle Crushing Test The appearance of steps or mutations during the compression process indicates that the particles are partially broken/crushed; compressive strength: blue particles > green particles. The crushing positions and crushing force values of different particles do not show consistent regularity.
| 2. Compressive strength of ternary & iron lithium particles Ternary and iron-lithium particles were prepared in the same way, and the stress and strain of the particles were evaluated by extrusion test of single particles: the extrusion force of ternary particles was greater than that of iron-lithium particles.
