| dc.description.abstractEn | Li<sub>1.11</sub>(Ni<sub>0.40</sub>Mn<sub>0.39</sub>Co<sub>0.16</sub>Al<sub>0.05</sub>)<sub>0.89</sub>O<sub>2</sub> was synthesized through coprecipitation of a mixed hydroxide followed by calcination with LiOH*H<sub>2</sub>O during 10 h at 500 °C and 950 °C. Electrochemical tests and their comparison with those obtained for an industrial Li(Ni<sub>1−<i>y</i>−<i>z</i></sub>Co<sub><i>y</i></sub>Al<sub><i>z</i></sub>)O<sub>2</sub> material reveal that Li<sub>1.11</sub>(Ni<sub>0.40</sub>Mn<sub>0.39</sub>Co<sub>0.16</sub>Al<sub>0.05</sub>)<sub>0.89</sub>O<sub>2</sub> shows good charge-discharge performance, even at high rate according to a protocol well established by car-makers for testing power abilities of batteries for electric and hybrid electric vehicles. In addition, this material shows a significant improvement in thermal stability in the highly deintercalated state (charged state of the battery) over the industrial material. Equivalent (or higher) energy and power densities with a significantly greater thermal stability make of Li<sub>1.11</sub>(Ni<sub>0.40</sub>Mn<sub>0.39</sub>Co<sub>0.16</sub>Al<sub>0.05</sub>)<sub>0.89</sub>O<sub>2</sub> an interesting candidate as positive electrode material for large lithium-ion batteries. | |
