Studio di film sottili di carbonio non grafitico mesoporoso come anodi modello per batterie agli ioni di sodio

Sodium-ion batteries are regarded as promising energy storage technologies to complement lithium-ion batteries. Despite hard carbon being already established as the benchmark anode, to this date the mechanism of sodium storage in hard carbon is still under debate, with the uncertainty over inaccessible pores particularly hindering a rational optimization of the material. Here, hard carbon thin films possessing ordered mesoporous structures are synthesised by a soft-templating and spin-coating procedure. Then, the films microstructures and pore morphologies are characterised and correlated to their electrochemical properties.
