Votre avis?
A part ce bref apercu :
Ca m' a tout l' air de la startup qui cherche des financements ........Partanen Europositron technology overcomes the existing difficulty and electropositive metal ions are reduced to metal through analytic and catalytic reactions in normal temperature and with a calculated electrical current. The flow resistance of the solution and the required excess voltage are taken into account.
The creation of aluminium hydroxide is eliminated and recharging for large number of cycles is possible. The technology applies to all existing methods of battery production including spiral wound sandwich examples. Another advantage of the Partanen Technology is that there is no "memory" effect as is found with many existing versions of today's batteries.
En France il y a eu des recherche sur la batterie à Aluminium, à Grenoble en particulier
