In order to reduce vehicle exhaust emissions and save fuel, most of well-known car manufacturers are gradually introducing the micro-hybrid (start–stop) vehicles. These vehicles achieve better fuel economy with lower exhaust emissions and a lower cost. There are currently two types of start–stop batteries, namely, the enhanced flooded design (EFB) and the absorptive glass-mat (AGM) design. It has been forecast that there will be a rapid growth of AGM batteries, while such increase will occur for EFB batteries in 2018 and overtake AGM batteries 2 years later. Compared with AGM batteries, EFBs display better performance in terms of cold-cranking, charge-acceptance, but inferior deep cycle-life and cycle-life under partial state-of-charge duty. Consequently, this presentation describes studies to solve the above shortcomings of the EFB through continuous selection, optimization and improvement of paste additives. The experimental campaign has resulted in the successful development of a new generation of paste additives that significantly improve the cold-cranking, charge-acceptance and cycle-life performance of EFBs.
