Template-free synthesis of Li[Ni0.25Li0.15Mn0.6]O2 nanowires for high performance lithium battery cathode

Li[Ni0.25Li0.15Mn0.6]O2 nanowires having an aspect ratio of several hundreds and with a diameter of about 30 nm were synthesized at a pH of 2 during a hydrothermal process at 200 degrees C for 5 h without using a template. The nanowires exhibited a first discharge capacity of 311 mA h g(-1) and a ra...

Zusammenfassung:Li[Ni0.25Li0.15Mn0.6]O2 nanowires having an aspect ratio of several hundreds and with a diameter of about 30 nm were synthesized at a pH of 2 during a hydrothermal process at 200 degrees C for 5 h without using a template. The nanowires exhibited a first discharge capacity of 311 mA h g(-1) and a rate capability of 95% at 4C (=1200 mA g(-1)).
