    摘要： Provided is a secondary battery system which can accurately detect a state of a secondary battery system (such as a secondary battery state and a secondary battery system failure). The secondary battery system (6) includes dV/dQ calculation means which calculates a dV/dQ value as a ratio of a change amount dV of a battery voltage V of a secondary battery (100) against a change amount dQ of an accumulation amount Q when the accumulation amount Q of the secondary battery (100) is changed. The secondary battery system (6) detects the state of the secondary battery system (6) by using the dV/dQ value.

    摘要： A control method for a lithium ion secondary battery includes performing a charging step of charging the lithium ion secondary battery with a predetermined quantity of electricity when the battery voltage of the lithium ion secondary battery has decreased to a lower limit battery voltage that is set at a value that falls within a range higher than (B−C) V and lower than or equal to (B−C+0.2) V where a maximum value of a positive electrode potential of a flat portion in a discharge positive electrode potential curve is B (V) and a negative electrode dissolution potential is C (V). It is possible to suppress a dissolution of a negative electrode current collector of the lithium ion secondary battery to prevent the service life of the lithium ion secondary battery from shortening because of an internal short circuit.

    摘要： A vehicle comprises a battery, i.e. a power storage unit having a capacity different from a reference capacity, a current sensor for detecting a current inputted to the power storage unit or outputted therefrom and delivering the detection value by converting it depending on the ratio of the capacity of the power storage unit to the reference capacity, and a controller performing current integration by receiving the output from the current detecting section and judging charged state of the power storage unit. The current sensor preferably comprises a sensor for measuring a current flowing through wiring connected with the power storage unit, and a converting section for converting the sensor output depending on the ratio of the capacity of the power storage unit to the reference capacity. When the capacity of the power storage unit is equal to n times of the reference capacity, the converting section delivers the sensor output while multiplying by 1/n.

First of all, it becomes feasible to maintain the electric connection between the active-material powder and the conductive material stably by adhering the conductive material to a surface of the active-material powder. Further, the fibrous conductive materials are bonded to the conductive material that is adhered to a surface of the active-material powder. It is feasible to maintain the electric connection by getting the fibrous conductive materials entangled to each other. That is, it is feasible to keep the electric connection even when strains occur in the electrode material, because the fibrous conductive materials absorb the strains to keep the mutual contacts; even if large strains occur, it is possible to maintain the electric connection, because it is not disconnected compared with that in conventional conductive materials.
