      abstract     = {Lithium-containing NASICON-structured materials are a
                      promising class of solid-state Li-ion conductors for
                      application in electrochemical energy storage devices.
                      Amongst the wide variety of possible compositions the
                      highest conductivities are reported for materials according
                      to the formula Li1+xMx(III)M2−x(IV)(PO4)3, in which the
                      substitution of tetravalent with trivalent metal cations
                      leads to incorporation of additional lithium ions and a
                      higher mobility of the charge carriers.For this study, we
                      surveyed more than 300 research articles about Li-NASICON
                      materials. The relations between composition, structure and
                      conductivity are evaluated to give a comprehensive overview
                      of published data on synthesized compositions. A special
                      focus is laid on Li1+xAlxTi2-x (PO4)3 as the single most
                      conductive and investigated material.The collected
                      conductivities show a wide scattering in a range of 10-10 S
                      cm-1 up to 10-3 S cm-1. The highest values are obtained for
                      materials with M(III) to M(IV) cation ratios of x =
                      0.3–0.4. Further characteristics for high conductivity are
                      evaluated and the rhombohedral structure as well as cation
                      sizes of around 50–60 p.m. are identified as crucial
                      prerequisites, favoring titanium-based compositions.
                      Considering the evaluated data, selected compositions are
                      suggested for further investigation to support future
                      research.},
