LITHIUM ALUMINUM TITANIUM PHOSPHATE (LATP)-CONTAINING POSITIVE ELECTRODES AND BATTERIES INCLUDING THE SAME

A positive electrode for a battery that cycles lithium ions includes a physical mixture of electroactive material particles and lithium aluminum titanium phosphate (LATP) particles. The electroactive material particles include a lithium-rich and manganese-based oxide. The electroactive material particles have a first mean particle diameter (D1), the LATP particles have a second mean particle diameter (D2), and a ratio of the first mean particle diameter to the second mean particle diameter (D1:D2) is greater than or equal to 4:1 and less than or equal to 1000:1.
