Claims27
A material that is silicon oxide in which a part of silicon is replaced by atom M, wherein the atom M is boron, aluminum, or gallium, wherein a proportion of oxygen atoms to silicon atoms is greater than 1.5 and less than or equal to 2.5.
A material that is Si(1-x)MxOy (M=B, Al, or Ga;
- x and y satisfy that a proportion of M atoms to silicon atoms is greater than or equal to 0.01 and less than or equal to 0.11 and a proportion of oxygen atoms to silicon atoms is greater than 1.5 and less than or equal to 2.5).
A material that is Si(1-x)MxO2 (M=B, Al, or Ga;
- 0.01/1.01≦x≦0.11/1.11).
A silicon oxide comprising atom M, wherein the atom M is boron, aluminum, or gallium, wherein a proportion of oxygen atoms to silicon atoms is greater than 1.5 and less than or equal to 2.5.
A silicon oxide comprising silicon, oxygen, atom M and lithium, wherein the atom M is boron, aluminum, or gallium, wherein a proportion of oxygen atoms to silicon atoms is greater than 1.5 and less than or equal to 2.5.
