  4. PAM Pb strap grid interface - sample collecting point 5 - 7 samples per cross section CL Pb AMCL PAM SGT positive plate structure Sub-layers in the SGTP electrode and sample collecting points XRD determinations in PAM/AMCL/CL phase composition and average crystallite size Source: B. Monahov, A. Kirchev and D. Pavlov,Influence of the current collector/PAM interface on the performance of VRLA batteries in the partial state of charge duty,presented at the STORE conference, Oct. 20-21, 2003, Aix-en-Provence, France

  5. SGTP battery at the end of cycle life: In-depth phase composition distribution in PAM • constant phase composition in PAM • major phase composition changes in the interface (CL+AMCL) • the interface resistance probably rises rapidly at discharge Source: B. Monahov, A. Kirchev and D. Pavlov,Influence of the current collector/PAM interface on the performance of VRLA batteries in the partial state of charge duty,presented at the STORE conference, Oct. 20-21, 2003, Aix-en-Provence, France

  6. In-depth crystallite size distribution in PAM b-PbO2 crystal size decreases markedly in the interface a-PbO2 / tet PbO crystal size decreases in the interface PbSO4 crystal size does not change in the interface and PAM

  7. Contributions to VRLAB based on the XRD method (in combination with EC polarisation and SEM) • Membrane model of the Pb/PbSO4 electrode • Semiconductor model of the Pb/PbO/PbSO4 electrode • Gel-crystal model of the PbO2 electrode. • Models of the influence of additives of Sb, Sn, Ag etc. on the structure of the Pb/PbOn/PbO2 electrode, the PAM and the corrosion layer. • Models of the corrosion mechanisms and the corrosion layer structure of pure lead and its alloys in sulphuric acid. • Model of the in-depth structure profile of the positive battery plate. • Model of the influence of expanders on the NAM structure. • Development of technologies for paste preparation, drying, curing and formation. • Models of the degradation processes in PAM and NAM.
