We present in this paper the main results of 7Li NMR on lithium intercalated in graphite, disordered pregraphitic cokes and other allotropic forms of hexagonal C-lattices like C60 and nanotubes. First we present the main parameters accessible by this technique when this new C-Li bonding is obtained, giving to the solid, the character of an alloy. The main observed shift has nothing to do with chemical shift but is a paramagnetic one produced by the presence of free e-wave on the lithium atom. A comparison is made of graphite intercalated by various methods either chemical or electrochemical or under high pressure. The dynamics of Li atoms inside the alloy is described. A chapter is devoted to the theoretical description of this new Li-C bonding from literature and various calculation derived from experiments. Then the new results obtained in porous carbons, favourable to anode production, helps us to describe the new used storage sites. Then preliminary results on fullerenes and nanotubes are given.
