Title (EN) BATTERY USING A METAL PARTICLE BED ELECTRODE
(FR) BATTERIE AVEC ELECTRODE A LIT DE PARTICULES METALLIQUES
Abstract:
(EN) A zinc-air battery (10) in a case (12) including a zinc particle bed (27) supported the current feeder (22) and diaphragm (26) on a porous support plate which holds the particles but passes electrolyte solution. Electrolyte is recycled through conduit between the support plate and top of the bed by convective forces created by a density differential caused by a higher concentration of high density discharge products in the interstices of the bed than in the electrolyte recycle conduit.
(FR) Une batterie zinc-air (10) dans un boîtier (12) comprend un lit (27) de particules de zinc qui soutient l'alimentation (22) en courant et le diaphragme (26) sur une plaque poreuse de support qui retient les particules mais laisse passer une solution d'électrolyte. L'électrolyte est remis en circulation dans un conduit entre la plaque de support et la partie supérieure du lit par des forces de convection créées par une densité différentielle qui résulte d'une concentration de produits de décharge de haute densité plus grande dans les interstices du lit que dans le conduit de recyclage de l'électroylyte.
