Composes ioniques du graphite avec NiCl2, BF−4 et K+ pour le stockage electrochimique de l'energie
Abstract Ionic graphite intercalation compounds are used as positive and negative electrodes in primary or secondary high energy density batteries. This concerns first stage compounds as C 7 NiCl 2 (charge transfer complex), C + 24 BF − 4 (graphitic salt) for positive pole and Li +δ C −δ , K +δ C −δ 8 for negative one. Good values of energy densities are reached with Li/C 7 NiCl 2 and LiAl/C + 24 BF − 4 secondary systems. The negative electrodes are reversible under some conditions and they show very good cations diffusivity between the graphite layers.
