How to Prolong and Restore Lead-acid Batteries

BU-804: How to Prolong Lead-acid Batteries Explore what causes corrosion, shedding, electrical short, sulfation, dry-out, acid stratification and surface charge A lead acid battery goes through three life phases: formatting, peak and decline (Figure 1). In the formatting phase, the plates are in a sponge-like condition surrounded by liquid electrolyte. Exercising the plates allows the

New Method Can Restore Used Lithium Batteries

A new recycling process might finally solve the dilemma of what to do with old lithium ion batteries in cell phones and laptops. A team of nanoengineers from the University of California San Diego has created an energy-efficient recycling process that restores used cathodes from spent lithium ion batteries to their original state, which could
