The electrochemical properties of carbon materials are mainly determined by the surface chemistry and accessibility of active sites. Incorporation of surface functional groups into the carbon materials attracts an attention in this context. This approach could be an efficient way for further optimization of carbon materials in order to reduce water consumption in lead carbon batteries. For that purpose, this presentation will focus on the investigation of carbon materials with different surface modifications and the electrochemical performance of the corresponding lead-carbon electrodes.

17:00 Simulation of a Thin Porous Lead-Dioxide Electrode with Fast and Inexpensive Computation Tool

Mikael Cugnet, Ph.D., Project Manager, CEA, France

Expensive finite element modeling tools are not necessary to achieve sufficiently accurate simulation results, as long as the geometry stays simple. There is still room to improve existing electrode models, even for such a mature technology as lead-acid. But believe it or not, physics-based modeling requires much more time and knowledge than money.

17:20 What Can We Learn from Electrode Surface Investigations for Battery Performance: An Overview of Various Battery Types and the Consequences for Lead Acid Batteries

Sven Ole Steinmueller, Ph.D., Instrumental Chemistry Specialists, Institute for Applied Materials, Energy Storage Systems, Karlsruhe Institute for Technology

Analysis examples from different finished and ongoing battery projects are presented including the surface analysis belonging to a project correlated with the design of artificial solid electrolyte interfaces revealing the analytical power of the combined approach with ToF-SIMS and XPS. At the end a comparison of the different battery systems and the conclusions for the investigation of lead acid and advanced lead acid battery systems are presented.

17:40 Performance Improvements from Discrete Carbon Nanotube Additives in Advanced Automotive Lead-Acid Batteries

Paul Everill, Ph.D., Vice President, Research and Development, Black Diamond Structures

Discrete carbon nanotubes can be dispersed in an aqueous solution and added directly to the pasting mix for either negative or positive lead-acid battery plates. These additives markedly improve the ability for batteries to be charged quickly without gassing, and to withstand many characteristic cycling protocols. These nanotubes, known as MOLECULAR REBAR®, can easily be incorporated into existing pasting lines. They have yielded benefits in full-scale production batteries in automotive applications. We show results for both flooded and VRLA configurations, and discuss the implications on battery design and performance in the field.

Gases generated from batteries were analyzed to investigate the water consumption mechanism during static over charge and micro cycling. The results will be compared and discussed to find a way to balance water consumption property and charge acceptance.

8:55 New PBX® Performance Additive for High DCA Start Stop Batteries

Paolina Atanassova, Ph.D., Global Applications Development Manager, Energy Materials, Cabot Corporation

Carbon additives are successfully used in commercial start-stop lead acid batteries for achieving high charge acceptance and cycle life, but higher emphasis on dynamic charge acceptance (DCA) and high temperature operation are needed to compete with Li-ion batteries and to maintain a competitive advantage of lead acid batteries for next generation micro-hybrid cars. PBX® 52 carbon additive is a formulated material that delivers excellent DCA and can provide up to 50% less water loss compared to Cabot’s PBX 51 carbon additive.

9:15 ArcActive’s Carbon Fibre-Based Negative Electrode: Latest Data

Stuart McKenzie, CEO, ArcActive, Ltd.

ArcActive began developing its novel Carbon Fibre-based negative electrode in 2011 with the ambition of delivering an LAB that delivered high and sustained DCA. Since this time, many technical challenges have had to be addressed, including scale up, achieving good performance on all standard tests (not just DCA) and manufacturing solutions. At this talk, the latest data, demonstrating excellent DCA (both sustained and WLTP) while delivering low water consumption, along with other test results, will be shared.

9:35 Development of an Improved Dynamic Charge Acceptance (DCA) Test for European Standardization

Jonathan Wirth, Research Associate, Chair for Electrochemical Energy Conversion and Storage Systems, RWTH Aachen University

New additives and innovative plate designs can significantly improve dynamic charge acceptance (DCA) of automotive lead-acid batteries and help to further reduce CO2 emissions. Existing lab tests, however, do not always accurately predict real-world performance of these lead-acid batteries in a run-in state. The presented study focusses on the development of a simplified DCA test for European norm EN 50231-6 while improving correlation to run-in performance in a 11 weeks reference test.

11:05 Scalability of Impedance and DCA for Different Sizes of Lead-Acid Cells

Julie Kowal, Ph.D., Research Scientist, University of Berlin

Cells with different electrode configurations are tested and compared concerning impedance and charge acceptance. The cells are cut from commercial starter batteries. The aim of the investigation is to analyze if measurements from smaller cells are representative for larger batteries.

11:25 The External Surface Area of Carbon Additives as Key to Enhance the Dynamic Charge Acceptance of Lead-Carbon Electrodes

Jochen Settelein, Ph.D., Research Scientist, Center for Applied Electrochemistry, Fraunhofer Institute for Silicate Research ISC

Specially synthesized carbon powders with a variation in the specific external surface area were investigated for the use as additive in the negative active material. Results from cyclic voltammetry on negative electrodes reveal that the external surface area of amorphous carbons exhibits a clear correlation to the electrochemical activity of lead-carbon electrodes. Higher DCA values can be observed for higher external surface area carbons.

12:05 Investigation on the Impact of Additives Given to Active Material in Order to Improve DCA of EFB with High Cycling Performance

Boris Steiner, Manager, Development and Product Management, MOLL Batterien

Over the past years, MOLL developed advanced EFB fulfilling the significantly increased technical requirements of car manufacturers for Micro-Hybrid Batteries. These batteries have virtually the same performance level as AGM design. This is contrary to the generally held belief that only AGM design can fulfill the rather difficult combinations of various technical requirements, particularly the combination of high cold cranking power and very good cycling performance. This paper gives new results of detailed investigations on the impact of additives on DCA, and about latest developments for further improvements of EFB.

Moderator: Christian Rosenkranz, Ph.D., Vice President Engineering & Product Development EMEA, Johnson Controls Autobatterien GmbH

The growth in start-stop batteries for the vehicle market has provided lead acid with opportunities for growth. This panel will examine what the technological advancements that will allow lead-based batteries to gain market share and compete effectively in the energy storage marketplace.

15:45 Leveraging Bipolar Batteries for High DCA 48V Hybrid Systems

Dan Moomaw, Lead Mechanical Engineer, Engineering, Gridtential Energy

As next-tier emissions regulations go into effect, 48V mild hybrid systems will proliferate the market, especially in the EU. Currently, lead batteries have difficulty addressing this market due to challenges with DCA and packaging restrictions. This presentation will detail recent test results in high-power automotive applications. Lead batteries remain a compelling solution for 48V mild hybrid powertrains when leveraging lightweight and efficient bipolar architectures.

16:05 Improvement of Lead Acid Battery Performance by Morphological Control and DCA Improvement Using SUPERSOFT-HYCYCLE™ and Specific Carbon Additives

Matthew Raiford, Ph.D., Process Engineer, RSR Technologies

The growth in grid storage and hybrid vehicle markets has presented many possibilities for lead acid batteries. However, improvements in cycling, gassing activity (water loss), and dynamic charge acceptance (DCA) must be achieved to adequately fulfill performance requirements. Water loss measurements and DCA-centered studies showed that improvements in DCA are possible from the leady oxide alone. Further improvements in DCA will be presented focusing the qualification and improvements offered by different carbon additives.

16:25 Lead Acid Batteries - Safety and Environmental Considerations

Juergen Garche, Ph.D., CEO, FCBAT

Lead acid battery production numbers are still growing, therefore quantitatively, also safety and environmental problems. Environmental problems during production and recycling of LABs still occur in developing countries but these problems are strongly reduced in industrial countries. But caused by general health problems of lead, the European Commission gives for the production of LABs only temporary derogations, which will be extended every 5 year as long there is unavailable a more health compatible and economically competitor product (Li-ion battery).
