NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY, METHOD FOR PRODUCING SAME, AND LITHIUM SECONDARY BATTERY COMPRISING SUCH NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY |
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 SiOx (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.
