S 3.2 Evaluation of Different
Glass Microfibre Separators and Membranes for VRLA Batteries Working
on High-Rate Partial-State-of-Charge (HRPSocC)
Contractors: Exide (Tudor), Daramic
Objective: Previous ALABC projects have explored the potential of
a variety of materials which could be used as separators in VRLA
cells employed for deep cycling. In such operation it is vital that
the separator prevent the positive active material expanding. Project
S 3.2 will explore the performance of a range of candidate separator
materials in high-rate partial-state-of-charge (HRPSoC) operation
(as in hybrid electric and 42 V vehicles) where the function of the
separator is rather different.
S 3.4 Separator Systems for VRLA Batteries in High-Rate Partial-State-of-Charge
(HRPSoC) Duty
Contractors: FIAMM, Hollingsworth & Vose
Objective: Project S 3.4 seeks to at least double the service life
of the VRLA battery in the HEV application through the use of an
optimized glass pasting paper system.
