FAQ
Q1: What is the significance of Co-001 as a classic material?
Co-001 represents one of the earliest and most thoroughly studied sodium-ion layered oxide cathodes. Its well-characterized electrochemical behavior, mature manufacturing processes, and extensive industrial validation make it a reliable baseline material for sodium-ion battery development and production.
Q2: How does the capacity of Co-001 compare to other cathode materials?
With 160 mAh/g initial specific capacity, Co-001 offers competitive capacity output. However, the use of cobalt makes it more expensive than copper-based alternatives like Cu-HC-010 or Cu-IND-009, which offer similar capacity at lower cost.
Q3: What is the recommended operating voltage range?
The recommended operating voltage range is 2.0 – 4.0 V vs. Na⁺/Na. Stable cycling performance and reliable capacity output are achieved within this window.
Q4: Can this material be used in both sodium-ion and lithium-ion batteries?
This material is specifically designed and optimized for sodium-ion battery systems. It is not recommended for lithium-ion battery applications.
Q5: How does the rate capability of 85% at 1C benefit applications?
The 85% capacity retention at 1C demonstrates good kinetic performance, ensuring reliable power delivery under moderate discharge rates. This makes Co-001 suitable for applications requiring both high capacity and reasonable power output.
