“…10,11 Ramsdellite titanium dioxide, TiO 2 (R), is one of the polymorphs of TiO 2 and is another promising candidate as a high potential anode. [12][13][14][15][16][17][18] Gover et al demonstrated that TiO 2 (R) has a high reversible capacity (275 mAh g ¹1 ) close to the theoretical capacity of 335 mAh g ¹1 . 16 In the literature, metallic Ti powder has been used for the preparation of ramsdelite LiTi 2 O 4 , LiTi 2 O 4 (R), which is a precursor of TiO 2 (R); however, the use of metallic Ti powder would have a safety problem in commercial production.…”

“…Esto parece lógico si se tiene en cuenta que la sustitución no afecta a la cantidad de Ti 4+ inicialmente presente, la cual contribuye, en su mayor parte, a la aparición, a bajo potencial (1.5 V), de una meseta de potencial casi constante cuando se reduce a Ti 3+ . Inferimos así que la utilidad que tendrían estos materiales como electrodo negativo en baterías del tipo ion litio sería idéntica a la ya propuesta para LiTi 2 O 4 (8).…”

“…En función de la cantidad de litio que se consigue albergar y del potencial medio de intercalación, algunas de estas ramsdellitas pueden ser consideradas como candidatas a electrodos en baterías de litio (6)(7)(8). En el caso particular de las ramsdellitas de titanio, la característica común es la existencia de un proceso, mediante el cuál el Ti 4+ es reducido a Ti 3+ a un potencial medio de 1.5 V, por lo que la aplicación de este tipo de materiales debe dirigirse hacia el electrodo negativo.…”

“…The strong candidates of the nanomaterials can be listed as carbon nanotubes (CNTs) [10], carbon nanofibers (CNFs) [97][98], graphene [11], Si nanowires [12], transition metal oxide nanoparticles [13] and so on. In particular, the LIB cell assembled by those nanostructured anodes have demonstrated their excellent electrochemical properties with respect to safety, high energy density, C-rate capability and long cycle lifetime relative to those of the conventional graphite anodes.…”
