摘要：
All-solid-state lithium-ion electrochemical cells comprising
(A) a cathode comprising
(a) particulate electrode active material according to general formula Li 1+x TM 1-x O 2 , wherein TM is Ni and, optionally, at least one of Co and Mn, and, optionally, at least one element selected from Al, Mg, and Ba, transition metals other than Ni, Co, and Mn, and x is in the range of from zero to 0.2, wherein at least 50 mole-% of the transition metal of TM is Ni, wherein said electrode active material is at least partially coated with a nanoparticulate zirconia or titania or hafnium oxide or alumina or niobium oxide or gallium oxide or tungsten oxide or molybdenum oxide species and wherein said particulate electrode active material has an average particle diameter (D50) in the range of from 2 to 20 µm,
(B) an anode, and
(C) a solid electrolyte comprising lithium, sulphur and phosphorus.
