ElektrischerbleisammlermitverminderterLadespannung.
Bekanntlich beträgt die zur Volladung einer Zelle üblicher Beschaffenheit nötige Spannung am Ende der Ladung, je nach der Stärke des Ladestromes, 3'7-2'8 V bei Bleisammlern. Die Erfindung bezweckt, diese Spannungen herabzusetzen und erreicht dies durch Zusatz geringer Mengen von Nickel, Kobalt, Kupfer oder Wolfram. Diese Stoffe werden der wirksamen Masse der negativen Platte in Form von Metallpulver oder Oxyden in Mengen bis zu 1' ; 0 zugefÜgt und vermindern dann die Elementspannung

ohne solchen Zusatz. Versuche haben ferner ergeben, dass Elemente nach der Erfindung keine geringere Entladespannung und Lebensdauer besitzen als die üblichen, und die als Nachkochen bekannte Gasentwicklung nur in geringem, für die Praxis nicht in Betracht kommendem Masse zeigen.
Anderseits wird durch die Erfindung der Nutzeffekt in Wattstunden erhöht, ferner ist es möglieh, von einem Netz bestimmter Spannung eine grössere Zahl von Elementen zu laden, und endlich ist bei Batterien, die während ihrer Ladung ein Netz konstanter Spannung speisen, nur eine geringere Anzahl von Schaltzellen nötig.

Electrical lead collector with reduced charging voltage.
It is well known that the voltage required to fully charge a cell of the usual nature at the end of the charge, depending on the strength of the charging current, is 3'7-2'8 V for lead collectors. The invention aims to reduce these stresses and achieves this by adding small amounts of nickel, cobalt, copper or tungsten. These substances are added to the effective mass of the negative plate in the form of metal powder or oxides in amounts up to 1 '; 0 added and then reduce the element stress
EMI1.1
without such addition. Tests have also shown that elements according to the invention do not have a lower discharge voltage and service life than the usual ones, and only show the evolution of gas known as post-boiling to a small extent, which is not considered in practice.
On the other hand, the invention increases the efficiency in watt-hours, it is also possible to charge a larger number of elements from a network with a certain voltage, and finally with batteries that feed a network of constant voltage while they are being charged, only a smaller number of Switching cells necessary.
