摘要： 100 parts by weight of a carbon material having irreversible capacity and 20 to 150 parts by weight of a lithium-containing complex nitride represented by the general formula Li 3-X M X N wherein M is at least one selected from the group consisting of Co, Ni, Mn and Cu, and wherein 0.2≦X≦0.8, are included in a negative electrode thereby to compensate for the irreversible capacity of the carbon material by the above-described nitride. This enables the maximum utilization of large capacity possessed by an amorphous carbon or low crystalline carbon, thereby making it possible to provide a non-aqueous electrolyte secondary battery having high capacity and excellent cycle reversibility.

摘要： The present invention relates to non-aqueous electrolyte secondary batteries comprising an positive electrode and a negative electrode capable of intercalating and de-intercalating lithium, a non-aqueous electrolyte and separators or solid electrolytes. The negative electrode contains, as a main component , composite particles constructed in such a manner that at least part of the surface of nuclear particles comprising at least one of tin, silicon and zinc as a constituent element, is coated with a solid solution or an inter-metallic compound composed of the element included in the nuclear particles and another predetermined element which is not an element included in the nuclear particles. To improve the ability of the battery, the composite particles mentioned above can include at least one trace element selected from iron, lead and bismuth. The porosity of a mixture layer at the negative electrode is 10% or more and 50% or less. The amount of the non-aqueous electrolyte, the thickness of the separators or the like is restricted in a specific value. The foregoing construction suppresses occurrence of an internal short circuit between the positive electrode and the negative electrode caused by expansion of the negative electrode materials , thereby achieving a high capacity battery with a superior charge/discharge cycle properties, which is suitable for a high-speed charging.

摘要： The present invention provides a battery-driven electronic device for which a long time use of the battery can be achieved and mobile communications equipment such as a portable telephone. Even if the time at which the output voltage of a battery 201 becomes below the supply voltage required by a load 206 including a power amplifier for wireless communications comes earlier than a conventional lithium ion battery because of its discharge characteristics that the battery voltage change ratio is 0.25 or more, a step-up and -down converter 200 operates as follows. When the output voltage of the battery is higher than the supply voltage required by the load, the voltage is set to a predetermined supply voltage by the step-down operation mode. When the output voltage of the battery is decreased and becomes lower than the supply voltage required by the load, the voltage is set to a predetermined supply voltage by the step-up operation mode. Thus, even for a battery employing a new material having a high energy density, a long term use of the battery can be achieved.
