LEAD-ACID STORAGE BATTERY PLATE (ALTERNATIVES) Russian patent published in 2005 - IPC

FIELD: electrical engineering; lead-acid batteries.

SUBSTANCE: according to first design alternate, lead-acid battery plate that has lead covered current-deflecting base uses aluminum or its alloys, or magnesium or its alloys, or titanium or its alloys as current-deflecting base, porosity of lead covering current-deflecting base closed with respect to the latter being 5 - 70%. In addition, current-deflecting base may be covered with lead or its alloys incorporating calcium, zinc, silver, and tin, porosity of lead or its alloys incorporating calcium, zinc, silver, and tin covering current-deflecting closed with respect to the latter being 5 - 70%. According to second design alternate, lead-acid battery plate that has lead covered current-deflecting base uses aluminum or its alloys, or magnesium and its alloys, or titanium and its alloys as current-deflecting base and in addition lead is covered with lead dioxide, porosity of lead applied to current deflecting base and that of lead dioxide applied to lead closed with respect to current-deflecting base being 5 - 70%. In addition, current-deflecting base may be covered with lead or its alloys incorporating calcium, zinc, silver, and tin, porosity of lead or its alloys incorporating calcium, zinc, silver, and tin closed with respect to current-deflecting base being 5 - 70%.

EFFECT: enhanced specific energy and service life of battery, enhanced mechanical strength of plate due to improved adhesive properties of lead covering current-deflecting base of plate.
