The main objective of the work described here was to develop a fast and efficient method to optimize the electrolytic medium in primary and secondary high density Li/SO2 batteries over a wide range of temperatures. Mixed aprotic solvents are frequently us...

The electrooxidation of 5-amino-1,4-naphthoquinone (ANQ) in acetonitrile leads to conducting (10-1 S.cm-1) functionalized polymer films of polyaniline- type bearing one quinone group per ANQ moiety, electroactive in organic or aqueous solvents. The polymer exchanges cations during the redox process of quinones and is therefore interesting for lithium ions batteries devices. ...

In this paper, the nonlinear behaviour of electrochemical cells submitted to high level current pulses is examined. Gas creation caused by current charge pulses, leads to an higher impedance of the cell. A battery state of charge (SOC) indicator based on this phenomenon is then proposed. Indeed, fusion of data provided by response to different current pulses (different levels, different duration, ...

Cette etude porte sur la conception d'un accumulateur echangeur de chaleur hybride (AECH) pour la gestion simultanee des energies solaire et electrique. Un modele mathematique reposant sur les equations de conservation de la quantite d'energie est expose. Il est developpe pour tester differents materiaux de stockage, entre autres, les materiaux a changement de phase ...

The evaluation of the thermophysical characteristics of Ni-Cd batteries for power supply of geostationary satellites was effected both theoretically and by microcalorimetry. The specific heat measured was 0.205 + or - 0.015 cal/gC, and heat capacity 205 +...

A series of work-rest, charge-discharge cycles was performed in preset conditions on Ni-CD batteries for establishing whether reconditioning treatment, i.e. very slow charging conditions after prolonged storage, would restore optimum discharge efficiency ...

Overcharging characteristics of Ni-Cd batteries for use in geostationary satellites were determined at-20, 0, 20 and 40 C. Results are presented in graphic and tabular form.
