    摘要： A lithium secondary battery employing as its negative electrode active material a material that increases in volume by alloying with lithium during charge achieves high discharge capacity and good cycle performance. The lithium secondary battery includes a negative electrode having a negative electrode active material (2) and a negative electrode current collector, a positive electrode having a positive electrode active material (1) and a positive electrode current collector (3), and a non-aqueous electrolyte. The negative electrode active material (2) is a material that increases in volume by alloying with lithium during charge. The negative electrode active material (1) is arranged so as to be on, and in contact with, the negative electrode current collector. The negative electrode active material (2) contains, when in an end-of-discharge condition, 8% or more of lithium with respect to the total capacity of the negative electrode active material (2) as measured when it does not contain lithium.

    摘要： In a thin type sealed cell utilizing a cell case made of a laminated material, a storage life and reliability of the cell is increased by preventing a sectional surface at an end of the laminated material from being exposed in the cell case, and thereby a leakage of an electrolyte out of the cell and a short circuit in the cell are avoided. This is achieved by disposing a resin layer on the inner surface of the cell case composed of a sheet type laminated material, and covering the sectional surface existing inside the cell case with resin.

    摘要： Capacity degradation due to charge/discharge cycles is suppressed in either a non-aqueous electrolyte secondary cell provided with a positive electrode including, as a positive electrode active material, a lithium-transition metal complex oxide having a layered structure and containing at least Ni and Mn as transition metals, and a negative electrode containing a carbon material as a negative electrode active material and having a higher initial charge-discharge efficiency than that of the positive electrode, or an assembled battery having a plurality of cells each of which is the secondary cell. A control circuit incorporated in the secondary cell or the assembled battery, or in an apparatus using the secondary cell or the assembled battery, monitors the voltage of the secondary cell or each of the cells in the assembled battery so that the end-of-discharge voltage of each cell is 2.9 V or higher.
