One scheme of preventing non-electrochemical self-neutralisation of protons and hydroxide ions is to exclude transport of another type of ion. The idea is demonstrated with a lithium ceramic super-ionic conductor (LISICON) film-based acid-alkaline hybrid DBPFC. A much higher cell... 

The use of framework structures to minimize AH for alkali-ion electrolytes has been demonstrated to provide a means of opening up the bottlenecks to cation motion in a number of oxides (Goodenough, Hong and Kafalas, 1976). Framework structures may provide one-dimensional tunnels as in hollandite, two-dimensional transport in planes as in the )S-aluminas, or three-dimensional transport as in NASICON and LISICON. Since one-dimensional tunnels are readily blocked, the two-and three-dimensional conductors are the more interesting.

Lithium carbonate can be used more directly as the auxiliary electrode with a lithium ion conductor, since the in situ formation of another carbonate phase is not required. Lithium ion conductors used with Li2CO3 include LISICON [163] and other Li3PO4-based electrolytes [164—173]. As with sodium ion conductors, Li2CO3-containing carbonates are used with lithium ion conductors [174, 175], The outputs of some examples of these lithium ion-conducting electrolyte-based sensors are shown in Figure 13.11 [163, 172-174]. 

The development of organic or inorganic lithium-ion conductor such as lithium super-ion conducting glass (LISICON). lithium iodide (Lit), solid polymer electrolytes(SPE) were activated with progress of a lithium battery. In these electrolytes, the technology of solid electrolyte is useful to improve the performance of batteries.

With regard to France, in addition to institutional laboratories, EDF has coordinated a National Research Agency project - Z/O. Faisabilite d um batterie Lithium-air (Feasibility of a Lithium-air battery) (project director Ph. Stevens) devoted to the development of a complete aqueous-electrolyte lithium-air cell with all its components. The metal lithium is protected by a first surface layer of LIPON (lithium phosphoms oxynitride) and then by a ceramic membrane of LISICON (Li Super Ionic Conductor LiM2(P04)3 with M=Ti, Zr, Ge, Hf). The declared performances are 100 mAh/cm (sufficient to deliver 500 Wh/kg) for current strength of 2 mA/cm at 30 C, and up to 6 mA/cm at 60°C. The lifetime is 38 cycles with a current strength of 10 mAh/cm. ... 

Crystalline inorganic electrolytes for Li-ion batteries can be divided into four main families of compounds, depending on their crystal strucmre (1) A-site deficient perovskite-type Li-ion conductors (2) Garnet-type Li-ion conductors (3) NASICON-type Li-ion conductors (4) LISICON-type Li-ion conductors.
