The invention claimed is: 1. A method comprising: suppressing gas evolution from a cathode material during a charge cycle by incorporating a nickel doped lithium rich cathode material of the general formula: Li ( 4 3 - 2 x 3 - y 3 - z 3 ) Ni x Co y Al z Mn ( 2 3 - x 3 - 2 y 3 - 2 z 3 ) O 2 wherein the cathode material is selected from one of Li 1.15 Co 0.15 Ni 0.2 Mn 0.5 O 2 Li 1.15 Ni 0.2 Co 0.1 Al 0.05 Mn 0.5 O 2 , or Li 1.1333 Ni 0.2 Co 0.15 Al 0.05 Mn 0.4667 O 2 . 2. The method of claim 1 , wherein the gas is at least one of molecular oxygen and carbon dioxide. 3. A method comprising: suppressing gas evolution from a cathode material during a charge cycle by incorporating a nickel doped lithium rich cathode material of the general formula: Li ( 4 3 - 2 x 3 ) Ni x Mn ( 2 3 - x 3 ) O 2 wherein x is equal to or greater than 0.06 and equal to or less than 0.12. 4. A method comprising: suppressing gas evolution from a cathode material during a charge cycle by incorporating a nickel doped lithium rich cathode material, wherein the cathode material is Li 1.066 Ni 0.4 Mn 0.533 O 2 . 5. The method of claim 3 , wherein the gas is at least one of molecular oxygen and carbon dioxide. 6. The method of claim 4 , wherein the gas is at least one of molecular oxygen and carbon dioxide. 7. A method comprising: increasing the charge capacity of a cathode material by incorporating a nickel doped lithium rich cathode material of the general formula: Li ( 4 3 - 2 x 3 - y 3 - z 3 ) Ni x Co y Al z Mn ( 2 3 - x 3 - 2 y 3 - 2 z 3 ) O 2 wherein the cathode material is selected from one of Li 1.15 Co 0.15 Ni 0.2 Mn 0.5 O 2 Li 1.15 Ni 0.2 Co 0.1 Al 0.05 Mn 0.5 O 2 , or Li 1.1333 Ni 0.2 Co 0.15 Al 0.05 Mn 0.4667 O 2 . 8. A method comprising: increasing the charge capacity of a cathode material by incorporating a nickel doped lithium rich cathode material of the general formula: Li ( 4 3 - 2 x 3 ) Ni x Mn ( 2 3
