Abstract
Provided is a negative electrode for a nonaqueous secondary battery which achieves both suppression of reductive decomposition of an electrolyte or an electrolytic solution and suppression of an increase in resistance. Also provided are a method for producing such a negative electrode and a nonaqueous secondary battery employing such a negative electrode. A polymer coating layer is formed so as to coat at least part of surfaces of negative electrode active material particles containing silicon oxide (SiO; 0.5≦x≦1.6). The polymer coating layer contains a cationic polymer having a positive zeta potential under neutral conditions. Since silicon oxide has a negative zeta potential, a thin uniform coating layer can be formed owing to Coulomb's force.
