CBI welcomes results of Spanish lead battery research program

December 6, 2023: The Consortium for Battery Innovation has released the results of a new pre-competitive research study focused on neutron diffraction and lead batteries.

The study — Operando analysis of the positive active mass of lead batteries by neutron diffraction — was supported by CBI’s technical program and conducted by Spanish research center Instituto de Nanociencia y Materiales de Aragón and the country’s Exide Group in Spain.

CBI said on November 30 that researchers’ main goal was to track the phase formation and distribution in charge/discharge processes of the electrodes of industrial lead batteries by neutron scattering experiments under operational conditions.

The results bring new insights into PbO₂ and PbSO₄ evolution in the positive plate and the estimation of charging efficiency.

The full paper is online.

Last month, the CBI launched its latest bid to identify new battery research projects for potential future funding — seeking proposals for studies covering either techno-economic analyses of lead BESS systems or material science studies into the failure of lead batteries in such systems.
