NEGATIVE ELEKTRODE FÜR LITHIUMSEKUNDÄRBATTERIE, VERFAHREN ZU IHRER HERSTELLUNG SOWIE LITHIUMSEKUNDÄRBATTERIE MIT EINER DERARTIGEN NEGATIVEN ELEKTRODE FÜR EINE LITHIUMSEKUNDÄRBATTERIE

摘要

A negative electrode 100 for a lithium secondary battery includes: a current collector 11; a negative-electrode active material body 12 supported by the current collector 11, the negative-electrode active material body 12 having a chemical composition represented as SiO x (0.1‰¦ x ‰¦1.2); and a covering layer 14 formed on the negative-electrode active material body 12, the covering layer 14 having a chemical composition composed of silicon dioxide. The covering layer 12 has a thickness which is greater than 1 nm and no more than 10 nm.
