A new, structurally refined Sn-C composite lithium battery electrode with unique stability and high electrochemical performance was investigated. The synthesis of the Sn-C nanostructured composite material was based on the infiltration of an organometallic tin precursor in an organic resorcinol (benzene-1,3-diol)-formaldehyde (methanol) gel, followed by calcination under argon. All the reagents were purchased from Aldrich and used without further purification. The resorcinol formaldehyde gel was prepared by mixing 28 mmol resorcinol with 120 mmol formaldehyde, 37% in water. Sodium carbonate was added as catalyst, with the ratio resorcinol/catalyst of 45 (mol/mol). It was observed that the new Sn-C composite material combines high stability with electrochemical performance.

Abstract
A new, structurally refined Sn-C composite lithium battery electrode with unique stability and high electrochemical performance was investigated.

All the reagents were purchased from Aldrich and used without further purification. The resorcinol formaldehyde gel was prepared by mixing 28 mmol resorcinol with 120 mmol formaldehyde, 37% in water. Sodium carbonate was added as catalyst, with the ratio resorcinol/catalyst of 45 (mol/mol). It was observed that the new Sn-C composite material combines high stability with electrochemical performance.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
