  title = {Ultrahigh power and energy density in partially ordered lithium-ion cathode materials},
  abstract = {<p><span>The rapid market growth of rechargeable batteries requires electrode materials that combine high power and energy and are made from earth-abundant elements. Here we show that combining a partial spinel-like cation order and substantial lithium excess enables both dense and fast energy storage. Cation overstoichiometry and the resulting partial order is used to eliminate the phase transitions typical of ordered spinels and enable a larger practical capacity, while lithium excess is synergistically used with fluorine substitution to create a high lithium mobility. With this strategy, we achieved specific energies greater than 1,100&thinsp;Wh&thinsp;kg</span><span>–1</span><span>&nbsp;and discharge rates up to 20&thinsp;A&thinsp;g</span><span>–1</span><span>. Remarkably, the cathode materials thus obtained from inexpensive manganese present a rare case wherein an excellent rate capability coexists with a reversible oxygen redox activity. Our work shows the potential for designing cathode materials in the vast space between fully ordered and disordered compounds.</span></p>},
