text: LISICON is an acronym for LIthium Super Ionic CONductor, which refers to a family of solids with the chemical formula LiZnGeO.
  The first example of this structure was discovered in 1977 with , providing a chemical formula of LiZn(GeO).  The crystal structure of LISICON consists of a network of [LiZn(GeO)] as well as 3 loosely bonded Li. The weaker bonds allow for the lithium ions to easily move from site to site, not needing to break strong bonds to do so.  Also, this structure forms large “bottlenecks” between the interstitial positions which these ions occupy, additionally lowering the energy required to move from site to site. These two factors allow for the lithium ions to diffuse quickly and easily through the structure. However, because of the shape of the channels through which these lithium ions can diffuse, they are limited to 2 dimensional diffusion. LISICON compounds have relatively high ionic conductivity, on the order of 10 S/cm at 25 °C. LISICONs readily react with lithium metal and atmospheric gases such as CO; as a result, their conductivity decreases with time.
