Capacity lithium alloys

Higher OCV values can be attained with lithium alloys (Figure 16), which are under study as negative insertion electrode materials for their high specific capacity... 

A renewed interest in noncarbonaceous lithium alloy electrodes arose recently as the result of the announcement by Fuji Photo Film Co. of the development of a new generation of lithium batteries based upon the use of an amorphous tin-based composite oxide in the negative electrode [13]. It is claimed that these electrodes have a volumetric capacity of 3200, AhL" which is four times that commonly achieved with carbonaceous negative electrodes, and a specific capacity of 800, mAhg" twice that generally found in carbon-containing negative electrodes. 

Although the electrochemical capacities of lithium alloys may be very large compared to that of carbon (for example, LiAl and Li Sn = 990 mAh/g), the large volume expansion due to the existence of two phases domains results... 

Today rechargeable lithium batteries - up from a few 100 mAh capacity - based on the reasons given have an anode from a lithium alloy or, more often, a nonmetallic...
