Changing shape of active mass may boost lead-acid tech

A British research team aims to redesign battery electrodes to boost the efficiency of lead-acid batteries for use in electric vehicles after receiving a government backing.

The University of Sheffield has received £100,000 ($123,000) to study ways of improving lead-acid batteries from the UK’s Engineering Physical Sciences and Research Council (EPSRC).

Additives boost lead-acid performance by 30%

Israel scientists have discovered adding single wall carbon nanotubes (SWCNT) on a lead-acid battery’s electrodes can improve its performance by more than 30%.

Researchers from Bar-Ilan University have found that electrodes containing SWCNT give prototype cells a greater specific capacity, improve cycle-life, have a lower resistivity, and a higher rate capability.
