DOCUMENT TYPE: Journal CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 38 The electrochem. stability, transport and interfacial properties of gel electrolytes contg. ethylene carbonate immobilized in a poly(acrylonitrile) (PAN) matrix with a Lithium (bis)trifluoromethane sulfonimide (LiTFSDI) salt have been studied for various LiTFSI concns. These gels have been evaluated for lithium batteries applications by lithium plating-stripping on a Cu foil, lithium-polypyrrole battery cycling lithium-graphite intercalations nd Li-ion battery prototypes. The good results obtained were attributed to high lithium transference nos. and relative stability of the lithium and lithiated graphite anodes in presence of ethylene carbonate. .

Rate effect on lithium-ion graphite electrode performance

Rate effect on lithium-ion graphite electrode performance. Tran, T. D.; Feikert, J. H.; Pekala, R. W.; Kinoshita, K.

DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 52, 78 The electrochem. performance of lithium-ion graphite electrodes with particle diam. at 6-44 mm was evaluated at different discharge (intercalation)/charge (deintercalation) rates (C to C/60). The electrode capacity depends on both the av. particle size and rate. With a simple rate program, the electrode performance is dependent on the cycling rate. The capacity of small graphite particles (6 mm) at C/2 rate was 80% of that achieved at C/24 rate (~372 mAh g-1). The capacity of large graphite particles (44 mm) obtained at fast rates (C/2) was only 25% of that obtained under near-equil. conditions (C/24). The electrode capacity, however, is nearly independent of the charge rate when the electrode is fully intercalated using a modified rate program contg.There are some commonly used reagents with their cas registry numbers 90076-65-6 and 7439-93-2 in this article. a const.-voltage held at 0.005 V (vs. Li+/Li) for several hours. The electrochem. behavior is related to the physicochem. properties of the graphite particles. .
