  • NEGATIVE ELECTRODE ACTIVE MATERIAL AND NEGATIVE ELECTRODE
    Publication number: 20250079447
    Abstract: A negative electrode active material including negative electrode active material particles, wherein the negative electrode active material particles contain silicon oxide particles coated with a carbon layer, at least a part of the silicon oxide particles contains at least one selected from the group consisting of Li2SiO3, Li4SiO4, and Li6Si2O7, and a part of at least an outermost layer of the negative electrode active material particles is coated with a layer of a plasticizer. This can provide: a negative electrode active material that can increase stability in slurry formation while achieving sufficient battery characteristics; and a negative electrode including such a negative electrode active material.

  • Authentication system, authentication server, authenticating method, authenticating program, terminal, authentication requesting method, authentication requesting program, and storage medium
    Publication number: 20090178127
    Abstract: Disclosed herein is an authentication system offering high degrees of security and convenience by use of two storage media. An automatic log-in system (100) requests a server (110) to perform a user authentication process using card-specific information (101) retrieved from an IC card (10) and password information (102) from a portable memory (11). The server (110) authenticates the user by acquiring a user ID and a password using the card-specific information (101) and password information (102). The card-specific information (101) and password information (102) constitute authentication request information, and the user ID and password make up authentication information. Following successful authentication of the user, the server (110) allows the user to log in; in case of unsuccessful authentication, the server (110) denies log-in.
