Attention has been given for some time to the use of lithium alloys as an alternative to elemental lithium. Groups working on batteries with molten salt electrolytes that operate at temperatures of 400-450 °C, well above the melting point of lithium, were especially interested in this possibility. Two major directions evolved. One involved the use of lithium-aluminium alloys [5, 6], whereas another was concerned with lithium-silicon alloys [7-9]. [Pg.361]

Lithium alloys have been used for a number of years in the high-temperature "thermal batteries" that are produced commercially for military purposes. These devices are designed to be stored for long periods at ambient temperatures before use, where their self-discharge kinetic be-... [Pg.361]

The first use of lithium alloys as negative electrodes in commercial batteries to operate at ambient temperatures was the employment of Wood s metal alloys in lithium-conducting button-type cells by Matsushita in Japan. Development work on the use of these alloys started in 1983 [10], and they became commercially available somewhat later. [Pg.361]

A series of experiments have been undertaken to evaluate the relevant thermodynamic properties of a number of binary lithium alloy systems. The early work was directed towards determination of their behavior at about 400 °C because of interest in their potential use as components in molten salt batteries operating in that general temperature range. Data for a number of binary lithium alloy systems at about 400 °C are presented in Table 1. These were mostly obtained by the use of an experimental arrangement employing the LiCl-KCl eutectic molten salt as a lithiumconducting electrolyte. [Pg.363]

The physical properties of lithium metal were given in Table 4.4. Despite its obvious attractions as an electrode material, there are severe practical problems associated with its use in liquid form at high temperatures. These are mainly related to the corrosion of supporting materials and containers, pressure build-up and the consequent safety implications. Such difficulties were experienced in the early development of lithium high temperature cells and led to the replacement of pure lithium by lithium alloys, which despite their lower thermodynamic potential remained solid at the temperature of operation and were thus much easier to use. [Pg.244]

As with all high temperature batteries, the materials problem in the lithium alloy-metal sulphide system is one of trying to develop low cost components which are able to withstand the hostile environment of the cell. The choice of insulators and separators is greatly restricted by the high stability of Li20 which excludes use of the common ceramics such as Al203 and... [Pg.257]

Recent encouraging results have been reported by Carter et al., who have obtained room temperature lifetimes in excess of 7000 h for encapsulated ITO/PPV/Ca devices at current densities of 60 mA/cm2.37 The polymer used was the PPV copolymer shown in Fig. 5.23, where the conjugation is interrupted by nonconjugated a -acetyloxy-/ -xylylene units. The efficiency of these devices was typically 0.02 lm/W. Devices operating at 80° C had lifetimes in excess of 1100 h. Carter et al., also reported devices based on the same emissive polymer giving efficiencies between 0.5 and 2 lm/W. These devices used a layer of conducting polymer (polyethylenedioxythiophene/polystyrene sulfonate) between the ITO and the PPV, and a sputtered aluminum/lithium alloy as the cathode. The devices... [Pg.149]

If the device is not designed to use a heat resistant material, a loss of its functionality during reflow soldering may occur. The lithium alloy may react with the electrolytic solution and other components of the battery to cause abrupt bulging or explosion. Therefore, materials resistant to the reflow temperature must be used for the electrolytic solution, separator, or gasket... [Pg.226]

At the heart of this device is a barium-lithium alloy, in a 1 to 4 atomic ratio [41], able to efficiently chemically absorb a large amount of nitrogen at room temperature, up to more than 2500 Pa-1 (N2)/g (alloy) [42]. [Pg.182]
