Title (EN) A METHOD OF MAKING HARD CARBON MATERIALS
(FR) PROCÉDÉ DE FABRICATION DE MATÉRIAUX DURS DE CARBONE
Abstract:
(EN) A non- amorphous hard carbon material, synthesized from Furan-ring containing compounds, is described. These non-amorphous hard carbon materials have a d002 peak in their X-ray diffraction patterns, corresponding to an interlayer spacing of >3.6 Ă, along with a prominent D- band peak in their Raman spectra. BET surface area values between 2 m2/gm and around 100 m2/gm can be obtained by controlling the processing parameters of temperature, time and heating rate. The higher surface area HCs - in Li-ion and Na-ion anode configurations - are capable of high charging rates up to 100C with a cycle life of up to 1000 cycles. Composites of these non- amorphous hard carbons with silicon and lithium compounds are also disclosed.
(FR) L’invention décrit un matériau dur non amorphe de carbone, synthétisé à partir de composés contenant un cycle de furanne. Ces matériaux durs non amorphes de carbone ont une crête d002 dans leurs motifs de diffraction aux rayons X, correspondant à un espacement intercouche > 3,6 Ă, ainsi qu’une crête importante en bande D dans leurs spectres de Raman. Des valeurs d’aire de surface de BET entre 2 m2/gm et environ 100 m2/gm peuvent être obtenues en contrôlant les paramètres de traitement de température, de temps et de taux de chauffage. Les HC d’aire de surface supérieure — dans des configurations d’anode à ions Li et à ions NA — sont capables de taux de charge élevés pouvant atteindre 100 C avec une longévité pouvant atteindre 1000 cycles. L’invention concerne également des composites de ces carbones durs non amorphes avec des composés de silicium et de lithium.
