摘要： An electrode precursor for lithium batteries includes a layer of an electrochemically active particulate material and a binder. The binder is soluble in the cell electrolyte so that the electrolyte extracts the binder from the particulate material after assembly, leaving a particulate layer substantially devoid of binder. Thus, the binder does not significantly decrease electrical conductivity of the layer in the cell and does not impede the ionic access to the layer. The soluble binder may be present in the electrode precursor in an amount sufficient to protect particulate which would otherwise react with the atmosphere.

摘要： A secondary electrochemical cell including a first electrode and a counteectrode each capable of reversibly incorporating an alkali metal, an alkali metal incorporated in at least one of the electrodes and an electrolyte solution containing an organic solvent, a salt of the alkali metal and at least one sequestering agent capable of complexing with the alkali moiety of the electrolyte salt, wherein the first electrode includes a carbon composition having a degree of graphitization greater than about 0.40. A method for intercalating alkali metal ions into a highly graphitic carbonaceous electrode material by contacting the electrode material with an electrolyte solution of an electrolyte solvent, an alkali metal electrolyte salt and at least one sequestering agent capable of complexing with the alkali metal moiety of the electrolyte salt, which electrolyte solution is also in contact with a counterelectrode, and applying a current between the electrode material and counterelectrode so that the alkali metal ions intercalate into the electrode material from the electrolyte solution, which sequestering agent substantially prevents cointercalation of the electrolyte solvent with the alkali metal ions into the electrode material.

摘要： Characterizing electrochemical cell components and a response of an electrochemical cell to a specified operating condition involves preparing a sample of an electrode material in contact with an electrolyte. Self-heating, power-temperature or power-time data is obtained for the sample using a calorimetry technique, such as by use of an accelerating rate calorimetry technique or a differential scanning calorimetry technique. A power function is developed for the sample using the self-heating, power-temperature or power-time data. The power function is representative of thermal power per unit mass of the sample as a function of temperature and amount of reactant remaining from a reaction of the sample electrode material and electrolyte. A first power function is developed that characterizes a reaction between the cathode material and the electrolyte in terms of thermal power per unit mass of a cathode sample material, and a second power function is developed that characterizes a reaction between the anode material and the electrolyte in terms of thermal power per unit mass of the anode sample material. An electrode material sample from which a power function is developed is prepared using less than about 100 grams of the electrode material, such as between about 1 and 10 grams, but may be as little as between about 1 milligram and 1 gram. A computer system and computer-readable medium are provided to electronically design and test cells of arbitrary size and shape using power functions developed for individual electrode/electrolyte combinations.

摘要： Carbonaceous compounds and methods for preparation are described wherein the compounds comprise a pre-graphitic carbonaceous host having organized and disorganized regions and wherein atoms of other elements are incorporated in the host without changing the structure of the organized regions. A carbonaceous insertion compound with large reversible capacity for lithium can be prepared using elements capable of alloying with lithium, such as Si, as the incorporated atoms. These insertion compounds are suitable for use as high capacity anodes in lithium ion batteries.

摘要： An electrode precursor for lithium batteries includes a layer of an electrochemically active particulate material and a binder. The binder is soluble in the cell electrolyte so that the electrolyte extracts the binder from the particulate material after assembly, leaving a particulate layer substantially devoid of binder. Thus, the binder does not significantly decrease electrical conductivity of the layer in the cell and does not impede the ionic access to the layer. The soluble binder may be present in the electrode precursor in an amount sufficient to protect particulate which would otherwise react with the atmosphere.
