typically, the diode will not be the issue in the charging circuit but the ic itself. this can fail and depending on where the diode is in circuit, it will overheat while preventing the backflow of current. you can test the diode as normal out of circuit to see if it is only allowing voltage drop in one direction.

'''++faisol kabir++''' … looks like a schottky rectifier diode. check the specs here and see if this matched your application:
