| dc.description.abstractEn | Li<sub>1.04</sub>(Ni<sub>0.40</sub>Mn<sub>0.40</sub>Co<sub>0.20−z</sub>Al<sub>z</sub>)<sub>0.96</sub>O<sub>2</sub>"<sup> </sup>(z = 0; 0.05 and 0.10) samples were synthesized using a coprecipitation<sup> </sup>method followed by calcinations at 500°C for 5 h and<sup> </sup>then at 950°C for 2 h. Structural and physico-chemical characterizations<sup> </sup>have shown that these materials were obtained pure with a<sup> </sup>small overlithiation ratio (Li/M = 1.01-1.03) and thus a significant exchange between<sup> </sup>the divalent nickel ions from the slabs and the lithium<sup> </sup>ions from the interslab spaces (between 4% for the non<sup> </sup>substituted material and 8% for the aluminum substituted ones). Aluminum<sup> </sup>substitution induces a decrease of the reversible capacity, but also<sup> </sup>a major improvement of the thermal stability in the deintercalated<sup> </sup>state (corresponding to the charge state of the battery). These<sup> </sup>results have thus shown that the composition Li<sub>1.01</sub>(Ni<sub>0.39</sub>Mn<sub>0.40</sub>Co<sub>0.15</sub>Al<sub>0.06</sub>)<sub>0.99</sub>O<sub>2</sub> is very<sup> </sup>attractive for large scale lithium-ion batteries to be developed for<sup> </sup>EV and HEV applications. | |
