Originální abstrakt

Atomic force microscopy of lead metal surface under layer of sulfuric acid, while polarized, is used to mimic in-situ visualization of charging/discharging a lead-acid battery. The motivation is to understand the microscopic phenomena influencing longevity of lead-acid batteries operated in partial state of charge. In addition to investigating a pure metal lead surface, two surface modifications were studied; a surface modified with glass fibers and TiO2 powder and a surface modified with glass fibers and graphite powder. The electrochemically active material is stabilized on the studied surface by both the carbon and TiO2 additives. Carbon renders better stability and efficiency in charging and discharging. However, both additives provide better efficiency than a surface without the additives.
