    摘要： Provided is a secondary battery with a negative electrode comprising a carbon powder capable of occluding and discharging cations, particles constituting the powder being consolidated with a binder, the binder consisting essentially of a polyimide or polyvinyl formal resin. In this battery, carbon particles are sufficiently consolidated and, are also adhered firmly to the negative electrode collector metal so that they hardly peel off from the negative electrode. As a result, the battery hardly decreases its capacity even when charge-discharge cycles are repeatedly run, thereby having a long cycle life. Furthermore, since the binder for the negative electrode comprises PI or PVF, containing no fluorine, there is little danger of the battery bursting or breaking even when the battery temperature becomes abnormally high, whereby the battery has high reliability.
