Abstract

In a lithium secondary battery using a negative electrode having a negative electrode mixture layer formed on a surface of a negative electrode current collector, the mixture layer made of a binder and negative electrode active material particles of silicon and/or a silicon alloy, charge-discharge cycle performance is improved without degrading the capacity per unit volume, by making the negative electrode mixture layer sufficiently adhere to the negative electrode current collector. The negative electrode has a negative electrode mixture layer composed of a binder and negative electrode active material particles of silicon and/or a silicon alloy. The negative electrode mixture layer is formed on a surface of the negative electrode current collector by sintering. Negative electrode active material particles are partially embedded in the negative electrode current collector.
