LiNi0.5+δMn0.5-δO2-A High-Rate, High-Capacity Cathode for Lithium Rechargeable Batteries

A cathode material (see figure) is shown to give a performance and cycle life comparable to that obtained with the LiCoO2 cathode now used in cellular phones and laptop computers. These performance features have been accomplished without the use of the expensive and toxic element cobalt and without...

Description
Summary:A cathode material (see figure) is shown to give a performance and cycle life comparable to that obtained with the LiCoO2 cathode now used in cellular phones and laptop computers. These performance features have been accomplished without the use of the expensive and toxic element cobalt and without compromising the volume energy density desired for hand‐held devices.
