Hard Carbon Core Technology Advantages
With a radius of 1.02 Å, sodium ions are over 35% larger than lithium ions (0.76 Å), making them unable to embed into traditional graphite layers. Hard carbon boasts a larger interlayer spacing (0.38–0.4 nm) and a rich microporous structure. This provides highly efficient pathways and abundant storage sites for sodium ions, fundamentally solving the core technological bottleneck of sodium-ion battery anodes.
