Electrochemistry twentieth century

Another factor also contributed to the appearance of new concepts in electrochemistry in the second half of the twentieth century The development and broad apphca-tion of hthium batteries was a stimulus for numerous investigations of dilferent types of nonaqueous electrolytes (in particular, of sohd polymer electrolytes). These batteries also initiated investigations in the held of electrochemical intercalation processes. 

The importance of this equality is that it will represent equilibrium and thus it provides an important bridge, that between electrochemical kinetics (to which an introduction is being given here) and thermodynamics. Before we deduce the condition for an equal rate of exchange of ions to electrode (as atoms) and atoms to solution (as ions), it is important to mention the name of a seminal figure in the histoiy of electrochemistry. J. A. V. Butler,5 the British physical chemist, was the first to write down a treatment of the kind discussed here, i.e., he was the first to connect the kinetic electrochemistry built up in the second half of the twentieth century with the thermodynamic electrochemistry that dominated the first half. 

Gumey was a solid-state physicist connected in his earlier days with Neville Mott, the most recognized solid-state physicist of the twentieth century. J.A.V. Butler was a physical chemist, less recognized at the time of the publication I am about to describe, but nevertheless without doubt one of only four or five founders of physical electrochemistry. ... 

Electrochemistry is one of the oldest defined areas in physical science, and there was a time, less than 50 years ago, when one saw Institute of Electrochemistry and Physical Chemistry in the chemistry buildings of European universities. But after early brilliant developments in electrode processes at the beginning of the twentieth century and in solution chemistry during the 1930s, electrochemistry fell into a period of decline which lasted for several decades. Electrochemical systems were too complex for the theoretical concepts of the quantum theory. They were too little understood at a phenomenological level to allow the ubiquity in application in so many fields to be comprehended.

The field of solid-state electrochemistry—the electrochemistry of solids— has developed rapidly since about the middle of the twentieth century. This was caused by the discovery of new solid elecfiolytes with high ionic conductivity and some fundamental publications which pointed out the importance of solid ionic conductors for the thermodynamic investigations. 

In the second half of the twentieth century, many academic institutions in the United States taught courses in electroanalytical chemistry and electrochemical engineering, but no American college, university, or technical institute taught any courses in applied electrochemistry. 

Because electrochemistry itself an interdisciplinary field, and is a part of so many different scientific disciplines and commercial applications, it is difficult to arrive at an accurate figure for the economic worth and annual profits of the global electrochemical industry. More reliable estimates exist for particular segments of this industry in specific countries. For example, in 2008, the domestic revenues of the United States battery and fuel cell industry were about 4.9 billion, the lion s share of which was due to the battery business (in 2005, the United States fuel cell industry had revenues of about 266 million). During the final decades of the twentieth century, the electrolytic production of aluminum in the United States was about one-fifth of the world s total, but in the twenty-first century competition from such countries as Norway and Brazil, with their extensive and less expensive hydropower, has reduced the American share. 

The absolute potentials of single electrodes have been a subject of interest since Ostwald, Nernst, and their contemporaries formulated the beginnings of modern electrochemistry in the nineteenth century. The twentieth century brought new methods of applying electrochemical measurements to analytical problems. For these, a knowledge of electrode potentials, or, alternatively, the activities of individual species of ions, could provide simplicity and accuracy not hitherto attainable. Nevertheless, ordinary thermodynamic procedures are incapable of measuring these quantities. 

After the first steps in the area of electrochemistry towards the end of nineteenth century, the beginning of twentieth century brought increased activity of Czech chemists. The mysterious electrolytic silver superoxide still attracted attention of V. Novak, O. Sulc, J. Baborovsky (1875-1946) (Fig. 3.1.2), and B. Kuzma (1873-1943) [4, 5]. Experiments to determine the voltage of anodic decomposition of sodium hydroxide were carried out by F. Plzak (1877-1944). The papers on the abovementioned topics were published in Czech or in German. 

The story about the development of electrochemistry in Moldavia has to start with one of the greatest electrochemists of the twentieth century, with Aleksandr Naumovich Fmmkin (Fig. 5.7.1) who was bom in Kishinev in 1895. 

The last decade of the twentieth century, the decade of Lithuanian independence, offered a lot of new opportunities in science and also new challenges, which the scientists at the Institute of Chemistry and other electrochemists had to face. It will be interesting to compare the development of electrochemistry and achievements in Lithuania during 50 years of isolation under Soviet occupation with those of the last decade of an independent country open to the whole world. We will try to do this after getting acquainted with the achievements of the most prominent Lithuanian electrochemists of twentieth century. 

Could there be more accomplishments in electrochemistry in Lithuania in the period after the World War II and could they be more significant Comparison of the achievements of Lithuanian electrochemists during the last decade of twentieth century with those of postwar period can help to find the answer to this question. The major drawback of the soviet system was the isolation of the Soviet Union from the outside world. Extremely limited and only formal contacts with colleagues...
