Electrochemical Testing:
Test Conditions:
Binder system: SBR/CMC
Composition ratio (MAG-106 : SP : SBR : CMC) = 91 : 5 : 2.4 : 1.6
Electrolyte components: LiPF6 / EC : EMC
Discharge: 0.1C down to 0.001 V
Charge: 0.1C up to 2.0 V, cutoff current 0.01C
Recommended Usage Guidelines:
Design Capacity:
The anode design capacity is 350 mAh/g.
For consumer lithium-ion batteries, an excess ratio of 6–8% is recommended;
for power-type lithium-ion batteries, an excess ratio of 10–15% is suggested.
Tap Density:
The electrode tap density (first roll) is 1.55 g/cm³.
Actual tap density should be controlled between 1.50–1.65 g/cm³, depending on battery structure and performance requirements.
Cycle Performance:
For cylindrical or prismatic aluminum-case consumer lithium-ion batteries:
≥ 80% capacity retention after 800 cycles at 1C charge/discharge rate.
For pouch-type power batteries:
≥ 80% capacity retention after 500 cycles at 1C charge/discharge rate.
