Negative electrode for nonaqueous electrolyte secondary batteries and nonaqueous electrolyte secondary battery |
abstract |
[Problem] If charging and discharging of a nonaqueous electrolyte secondary battery are repeated, a gas is generated and consequently the battery capacity is decreased. [Solution] The above problem is able to be solved by providing a negative electrode for nonaqueous electrolyte secondary batteries, which contains: a negative electrode active material that has an average operating potential of 0.5 V (vs. Li/Li + ) or more but less than 2.0 V (vs. Li/Li + ) during intercalation and deintercalation of lithium ions; a conductive assistant that is composed of carbon nanotubes having a diameter of 100 nm or less; and a binder that is composed of a polymer having an acidic functional group. |
