The Consortium for Battery Innovation (CBI) has developed a technical program to advance lead-acid battery technology to deliver dependable, safe, cost-efficient, and sustainable batteries. The focus is on energy storage systems (ESS), principally 12 V automotive batteries and motive power applications, such as forklift and golf traction batteries. The aim is to improve the lifetime, charge acceptance/recovery, and total discharge energy throughput during the battery life of lead-acid batteries. There are several projects across the EU and USA that cover not only application specific but also fundamental research, such as PbSO4 crystal growth and dissolution under different conditions to understand electrochemical processes in the various components of lead batteries. This presentation is concentrated on the main findings obtained from the current research projects. These include: (i) in-operando Neutron diffraction of lead-acid batteries under ESS duty cycles; (ii) bipolar batteries for ESS; (iii) study of BaSO4 particle size, coating and impact on ESS performance; (iv) opportunity fast charging and improved energy throughput for motive power applications; (v) in situ imaging and phase analysis of cell lead-acid battery materials from auxiliary battery cycling testing regimes.
Begüm Bozkaya received a M.Sc. degree in Materials Science from Technical University of Munich and a PhD degree in Chemistry from Julius-Maximilian-Universität Würzburg. Her master´s thesis was based on the investigation of carbon additives on C/Si anode materials for lithium-ion batteries. During her PhD at Fraunhofer ISC, she has investigated the effects of carbon additives in negative plates for lead-acid batteries. Begüm has worked on several industrial projects for the past six years that have mainly focused on the enhancement of the dynamic charge acceptance.
