TL;DR: In this article, the authors consider the fundamental problems in the design of lithium-sulfur batteries (LSBs): low practical specific energy, rapid decrease in capacity during cycling, and high self-discharge rates.
Abstract: This work considers the fundamental problems in the design of lithium-sulfur batteries (LSBs): low practical specific energy, rapid decrease in capacity during cycling, and high self-discharge rates. We demonstrate that these problems will be solved by the provision of an optimum combination of the rates of electrode and corrosion processes in lithium-sulfur batteries during cycling.

TL;DR: In this article, the results of basic studies in the synthetic-diamond electrochemistry are summarized: the electrochemical kinetics, photoelectrochemistry, electrochemical impedance spectroscopy.
Abstract: Because of its extraordinary chemical stability, diamond is a perspective electrode material to be used in electrochemistry and electrochemical engineering. In this review-article, the results of basic studies in the synthetic-diamond electrochemistry are summarized: the electrochemical kinetics, photoelectrochemistry, electrochemical impedance spectroscopy. Relations between the semiconductor nature and crystal structure of diamond and its electrochemical behavior are revealed. Prospects for using diamond electrodes in the electroanalysis, electrosynthesis, and environmentally-oriented industry are outlined.

TL;DR: In this paper, a modified-donnan (mD) approach is used to model ion transport and electrochemical reactions in a porous electrode, and the influence of the charge transfer kinetics on the chemical charge in the electrode is investigated.
Abstract: We present porous electrode theory for the general situation of electrolytes containing mixtures of mobile ions of arbitrary valencies and diffusion coefficients (mobilities). We focus on electrodes composed of primary particles that are porous themselves. The predominantly bimodal distribution of pores in the electrode consists of the interparticle or macroporosity outside the particles through which the ions are transported (transport pathways), and the intraparticle or micropores inside the particles, where electrostatic double layers (EDLs) are formed. Both types of pores are filled with electrolyte (solvent plus ions). For the micropores we make use of a novel modified-Donnan (mD) approach valid for strongly overlapped double layers. The mD-model extends the standard Donnan approach in two ways: (1) by including a Stern layer in between the electrical charge and the ions in the micropores, and (2) by including a chemical attraction energy for the ions to go from the macropores into the micropores. This is the first paper where the mD-model is used to model ion transport and electrochemical reactions in a porous electrode. Furthermore we investigate the influence of the charge transfer kinetics on the chemical charge in the electrode, i.e., a contribution to the electrode charge of an origin different from that stemming from the Faradaic reaction itself, e.g. originating from carboxylic acid surface groups as found in activated carbon electrodes. We show that the chemical charge depends on the current via a shift in local pH, i.e. “current-induced charge regulation.” We present results of an example calculation where a divalent cation is reduced to a monovalent ion which electro-diffuses out of the electrode.

TL;DR: In this paper, a review summarizes the development of lithium ion batteries beginning with the research of the 1970-1980s which lead to modern intercalation type batteries, material developments are outlined with a look at cathode materials, electrolyte solutions and anode materials.
Abstract: The review summarizes the development of lithium ion batteries beginning with the research of the 1970–1980s which lead to modern intercalation type batteries. Following the history of lithium ion batteries, material developments are outlined with a look at cathode materials, electrolyte solutions and anode materials. Finally, with lithium sulfur and lithium oxygen batteries two post intercalation type lithium batteries are discussed. The focus of the material discussions lies on basic understanding, problems and opportunities related to the materials.
