The positive electrode|electrolyte interface plays an important role in all-solid-state Li batteries (ASSLBs) based on garnet-type solid-state electrolytes (SSEs) like Li6.4La3Zr1.4Ta0.6O12 (LLZTO).
Lithium-ion batteries (LIBs), which use lithium cobalt oxide LiCoO 2, lithium nickel cobalt manganese oxide, lithium nickel cobalt aluminum oxide or lithium iron phosphate LiFePO 4 as the positive electrode (cathode) and graphite as the negative electrode (anode), have dominated the commercial battery market since their introduction in the 1990s.
Following this initial confirmation of redox reversibility, a structural battery was fabricated using LFP-deposited CF as the positive electrode and pristine T800 CF as the negative electrode.
