摘要:
A number of materials with the composition Li1nullxNinullMnnullConullMnullnullO2nullzFz (MnullnullMg,Zn,Al,Ga,B,Zr,Ti) for use with rechargeable batteries, wherein x is between about 0 and 0.3, nullis between about 0.2 and 0.6, null is between about 0.2 and 0.6, null is between about 0 and 0.3, null is between about 0 and 0.15, and z is between about 0 and 0.2. Adding the above metal and fluorine dopants affects capacity, impedance, and stability of the layered oxide structure during electrochemical cycling.
