摘要: Abstract The electrochemical reaction of lithium with the skutterudite-type CoP3 compound has been studied. To follow mechanism, X-ray diffraction (XRD), 7 Li nuclear magnetic resonance (NMR) and absorption (XAS) experiments have carried out. During first phase, cobalt is reduced lithium-phosphide formed. reversible process observed during subsequent cycles consists formation Li3P from its elements, giving a maximum in gravimetric capacity 487 mAh/g.
