This paper reports the benefits of a carbon coated aluminum current collector specifically designed to promote LiNi1.5M1.5O4 (LNMO) as high potential positive electrode material. This underlayer allows efficient protection of the aluminum surface in 1 M LiTFSI/[EC/DMC] electrolyte for more than 100 cycles (C/2 – D/2) in experimental conditions mimicking the electrochemical response of LNMO. The design of such coating appears therefore as a very encouraging strategy to make the use of imide-based electrolytes possible despite their corrosive properties towards aluminum. The as-developed carbon coating also reduces the interfacial impedance of an LNMO-based electrode by a factor of 5 in 1 M LiPF6/[EC/DMC] electrolyte therefore paving the way to accelerate the industrial deployment of safe “5 V” Li-ion batteries. |
