High Precision Cycling (HPC) for Coulombic Efficiency (CE) Measurements
Quantifying the influence of changes in the electrodes or electrolytes on the battery lifetime, under classical testing conditions requires extremely long times. Contrarily to simply cycling cells until they reach their end of life, only making a few Coulombic Efficiency (CE) measurements can reduce the duration of the experiment to 3-4 weeks, while providing a tool to evaluate and compare the stability of different cells.
This webinar will focus on the following key topics:
• What is the coulombic efficiency ?
• How can it be used to rapidly estimate battery lifetime ?
• What is required in terms of accuracy and precision of the instruments ?Presenter

A Raft of EVs and Hybrids are Coming – Will the Buyers Follow?
Current sales trends for hybrid and electric vehicles will be detailed as will the effect of public policy on these vehicles. California is moving forward even as the US EPA and NHTSA pull back, with states aligning with California that represent 40% of total US sales.
There is a plethora of new products coming from a variety of automakers, with certain automakers taking their own unique approaches, which will of course differentially affect suppliers and consumers. While China may be “ground zero” for product introductions and sales, the US will see a significant number of new products, particularly if we include vehicles that are “electrified” (as opposed to fully electric vehicles).
Changes in technology affecting the cost and therefore the price to consumers will be discussed.
This webinar will focus on the following key topics:
• Current Sales Trends Regarding EVs and Hybrids
• Current Status of the EPA/NHTSA Midterm Review
• Current Status of CA Regulatory Intentions Regarding Fuel Economy and Zero Emission Vehicles
• Automaker EV Plans Through 2025
• Other Factors Affecting EV and Hybrid Sales in this PeriodPresenter

Energy Storage RTE Tutorial Course 1/3: What is Round Trip Efficiency (RTE)? Why is it Important? How Much Does it Cost?
In the first of this three-part webinar series, a definition of RTE will be presented along with simple system equations that are important to its understanding, determination and management. RTE for some popular battery systems i.e. Lead Acid, Lithium Ion, Vanadium Redox and Nickel Zinc will be computed as examples, and their variation with common variables such as rate, capacity variability & SOC swing will be discussed. The costs of Round Trip inefficiency can be significant, and are experienced by customers either in higher energy generating capital costs and/or higher operating expenses. The calculation of these higher costs will be reviewed, and there will be a discussion on the key industry variables that influence them. Different geographic and customer markets will be considered.
This webinar will focus on the following key topics:
• The Importance of RTE to battery selection decisions
• How does RTE impact CAPEX and/or OPEX for energy storage
• How is RTE defined and how can it be derived – comparison of different systems
• An introduction to ancillary equipment energy lossesPresenter

Energy Storage RTE Tutorial Course 2/3: Ampere-Hour (Ah) RTE and Voltage Polarization Energy Losses
Many aqueous systems have water electrolysis to contend with, and above 70-80% SOC, RTE losses from this competing reaction can be significant. Management of these losses has been evolving for decades, and there are now tried and tested methods mostly related to charging algorithms & partial state of charge (pSOC) cycling. These methods will be reviewed. Relevant for every battery chemistry, Cell Voltage factors, will be separated into eight different components, four each, for the cathode and anode. These will be presented & described. The variables that affect them will be reviewed, including the effects of age & cycling and methods for their ongoing measurement. Techniques to reduce and mitigate polarization will be detailed & possible benefits will be quantified in terms of RTE & cost for different scenarios.
This webinar will focus on the following key topics:
• Ah Efficiency losses in aqueous systems
• Types of Voltage Polarization losses for all systems
• Strategies and plans for reducing & mitigating efficiency losses
• Improvement potential for different systemsPresenter
