摘要：
Electrochemical cells are disclosed that include electrodes comprising a composite that includes an active material, graphite and a binder. The amount of graphite in the composite is greater than about 20 volume percent of the total volume of the active material and graphite in the composite. The porosity of the composite is less than about 20%. The cells also comprise an electrolyte that includes a vinylene carbonate derivative or a halogenated ethylene carbonate derivative.
