In this study, salicylhydroxamic acid (SHA), which exhibits superior flotation performance to conventional collector benzohydroxamic acid (BHA), was first introduced in ilmenite flotation. The addition of lead(II) can significantly increase the recovery of ilmenite using SHA as collector. Thus, the adsorption mechanism of SHA on lead(II) …

The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for us…

Lead Acid Battery - an overview
Lead-acid batteries should never be allowed to remain for a long period in a discharged state because lead sulfate could harden and permanently clog the pores of the electrodes. Before storing it for a long time the battery should be completely charged, then the electrolyte should be drained so that the battery is stored dry.
In this review, the possible design strategies for advanced maintenance-free lead-carbon batteries and new rechargeable battery configurations based on lead acid …

Cobalt (Co) and lithium (Li) were extracted from pure LiCoO2 powders and actual cathode material powders from the spent lithium-ion batteries (LIBs) after l-ascorbic acid dissolution via a mechanical activation process. The influences of activation time and rotation speed on the leaching were discussed. The mechanism of the improved …
In 1860, the Frenchman Gaston Planté (1834–1889) invented the first practical version of a rechargeable battery based on lead–acid chemistry—the most successful secondary battery of all ages. This article outlines Planté''s fundamental concepts that were decisive for later development of practical lead–acid batteries.
