TL;DR: In this article, a PbO 2 cathode of a lead-acid battery is activated by electrochemical doping with colloidal solution of carbon which is subjected to electrochemical modification endowed with --C--O--O- and C-O-- groups on its surface.
Abstract: A PbO 2 cathode of a lead-acid battery is activated by electrochemical doping with colloidal solution of carbon which is subjected to electrochemical modification endowed with --C--O--O-- and C--O-- groups on its surface. The battery shows the following advantageous characteristics: (i) high charge current without extraordinary increase in the temperature; (ii) high discharge current; and (iii) the increase in the lifetime of the battery. This process is applicable for the revival of degraded batteries and formation treatment of electrodes of new batteries. Thus, lead-acid batteries of high performance can be obtained.

TL;DR: In this paper, two techniques of electrochemical intercalation were found to increase lithium capacity of electrode made of commercial graphitic carbon, where cell initially discharged (lithium allowed to intercalate into carbon electrode) at constant current density of 0.28 mA/cm(sup2).
Abstract: Two techniques of electrochemical intercalation found to increase lithium capacity of electrode made of commercial graphitic carbon. In first technique, cell initially discharged (lithium allowed to intercalate into carbon electrode) at constant current density of 0.28 mA/cm(sup2). Second, similar to first except involves two discharges at different currents.

TL;DR: Oyama et al. as discussed by the authors proposed a new composite made from two readily available organic polymers with either conducting or electron-exchange (redox) properties, which function as a highvoltage and high-capacity electrode for lithium batteries.
Abstract: BATTERIES are the Achilles' heel of the much vaunted information superhighway, for which portable electronics are in increasing demand. Another driving force is the electric car. Researchers and industrialists alike will therefore be watching closely for verification and further developments of an advanced battery reported by Noboru Oyama and colleagues at the Tokyo University of Agriculture and Technology (N Oyama et al. 1995 Nature 373 598). They propose a new composite made from two readily available organic polymers with either conducting or electron-exchange (redox) properties. This material functions as a high-voltage and high-capacity electrode for lithium batteries – until now only a few transition metal oxides met such criteria. The experimental battery also uses a non-conventional gel electrolyte, making it an all solid-state device.
