The principal use of titanium sulfides is as a cathode material in high efficiency batteries (11). In these applications, the titanium disulfide acts as a host material for various alkali or alkaline-earth elements. [Pg.133]

Lithium has a number of important and interesting uses. In recent years, it has been used to make lightweight, efficient batteries. Compounds of lithium have also been used to treat a mental disorder known as bipolar disorder. [Pg.315]

We re people on the go... with laptop computers, portable drills, and electronic games that kids can play in the car. To keep all of these tools and toys working, we need hatteries, and because the newer electronic devices require more power in smaller packages, scientists are constantly searching for stronger and more efficient batteries. The goal of this section is to help you understand how batteries work and to describe some that may be familiar to you and some that may be new. [Pg.224]

This will lead to increased reliance of our society on batteries and will spur the search for new, more efficient batteries. [Pg.635]

The calculators, electronic games, digital watches, and portable audio players that are so familiar to us are all powered by small, efficient batteries. The common dry cell battery was invented more than 100 years ago by George Leclanche (1839-1882), a French chemist. In its acid version, the dry cell battery contains a zinc inner case that acts as the anode and a carbon rod in contact with a moist paste of solid Mn02, solid NH4CI, and carbon that acts as the cathode (Fig. 18.14). The half-reactions are complex but can be approximated as follows ... [Pg.843]

When batteries are set to deep discharge cycling the charge current reaches maximum values of 0.5 C20 A (usually it is 0.2 C20 A). At these current rates the negative plates charge efficiently. Batteries for hybrid electric vehicle applications, however, have to be... [Pg.333]

Increasing the reliahihty, and hence the safety, of WSNs is an objective that requires an interdisciplinary and complex approach. Several factors are important in the analysis of the level of safety of WSNs. One way to attain this objective is hy means of data quality (DQ) evaluation. Several academic studies deal with the issues of efficient battery use, wireless com-mimication fault tolerance and data processing and... [Pg.824]

Electrochemists study the chemical changes produced by electricity, but they are also concerned with the generation of electric currents due to the transformations of chemical substances. Whereas traditional electrochemists investigated such phenomena as electrolysis, modern electrochemists have broadened and deepened their interdisciplinary field to include theories of ionic solutions and solvation. This theoretical knowledge has led to such practical applications as efficient batteries and fuel cells, the production and protection of metals, and the electrochemical engineering of nanomaterials and devices that have great importance in electronics, optics, and ceramics. [Pg.592]

At certain velocities therefore the force is so reduced that the bars are no longer accelerated. He concluded "I almost despair of the success of electro-magnetic attractions as an economical source of power" (15) - for, his electro-magnetic engines simply did not compare to the fuel efficiency of steam engines without vastly more efficient batteries Joule could not see how to improve his machine. [Pg.52]

The development of efficient batteries and even more efficient fuel cells has led to the development of electric vehicles that, in some cases, are pollution-free. Fuel cells are also becoming cost-competitive as a way to generate power grid electricity. They are cleaner, more efficient, and environmentally friendlier than conventional electricity-generation technology. Will our society adopt the changes that come with this new, environmentally friendly technology, or will we continue as before ... [Pg.390]

Another area for development is the power supply. Lithium-ion battery technology has been there for quite a long time, and it is time to develop a more compact and efficient battery system that could be used to develop lightweight heating textiles. [Pg.131]

Large-scale accelerated life testing of space-based batteries, including Ni-Hj, Ni-Cd, and Ni-HM batteries, is necessary to achieve reliable data on aging effects. Simulations, both real-time and accelerated life-cycle testing data must be achieved on GEO and LEO communications systems. These data will identify early detection of aging effects in the electrochemical cells deployed in the space-based batteries. In brief, this type of information will form the basis for more robust and efficient batteries with high cycle life. Test results on specific batteries as a function of various pertinent parameters are summarized in Table 2.14. [Pg.72]

The Peukert law takes into account the internal resistance and recovery rate of a battery. A value close to 1 indicates a well-performing battery with good efficiency and minimal loss a higher number reflects a less efficient battery. Figure 8.3 illustrates the available capacity as a function of ampere with different Peukert ratings. [Pg.215]
