Silicon has attracted huge attention in the last decade because it has a theoretical capacity ∼10 times that of graphite.

Na ₃ MnCO ₃ PO ₄ offers a specific capacity of 176.7 mA h g ⁻¹ , reaching 92.5% of its theoretical if electronic conductivity is sufficient.106

Interface engineering fundamentally revolutionizes magnesium-based hydrogen storage systems by orchestrating atomic-scale interactions and mass transport pathways through synergistic integration of structural design and compositional modification.
