Lithium thermal properties

It was noticed in some instances that alkali-metal impurities in alumina, or in the ceramic honeycombs, adversely influence the catalyst activity. For example, spodumene (lithium aluminum silicate) was found unsuitable for use as catalyst support, although it had good thermal properties.

The effectiveness of carbon nanotubes as conductive filler to cathode of lithium ion batteries (Fig. 17) was demonstrated by adding small amounts of both carbon nanotubes and acetylene blacks to LiCoOa-based active materials [77]. The merits of using carbon nanotubes together with acetylene blacks as cathode fillers include not only the enhancement of the electrical and the thermal properties of the electrode, but also the enhancement of the density of the electrode and the shortening of the electrolyte absorption time. We envisage that the use of carbon nanotubes as multi-functional fillers will increase in both cathode and anode materials for lithium ion secondary batteries.

Loop Tests Loop test installations vary widely in size and complexity, but they may be divided into two major categories (c) thermal-convection loops and (b) forced-convection loops. In both types, the liquid medium flows through a continuous loop or harp mounted vertically, one leg being heated whilst the other is cooled to maintain a constant temperature across the system. In the former type, flow is induced by thermal convection, and the flow rate is dependent on the relative heights of the heated and cooled sections, on the temperature gradient and on the physical properties of the liquid. The principle of the thermal convective loop is illustrated in Fig. 19.26. This method was used by De Van and Sessions to study mass transfer of niobium-based alloys in flowing lithium, and by De Van and Jansen to determine the transport rates of nitrogen and carbon between vanadium alloys and stainless steels in liquid sodium.
