Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios
The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.
This webinar will focus on the following key topics:
• Creating multi-cell packs
• Containing thermal runaway events

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 systems

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 losses

Accelerating Launch of New Battery Technologies by Expediting Samples Through Collaborative Partnerships
Polaris is a processing lab that accelerates new lithium ion battery developments resulting in faster delivery of samples. It provides processing services to accelerate the optimization of recipes for battery developers. Using its services, customers can avoid delays in launching products due to internal funding and staffing constraints.
Services include anode and cathode electrode mix and coat trials, pouch stack cell assemblies, cell and material analytical testing services, business advisory services, and a link to high volume production.
Two major roadblocks facing battery technology companies are addressed: 1) Startups lack staffing, process knowledge, funding, and equipment to develop samples, and 2) Commercialization of new battery technologies is capital intensive and takes long time to pass quality standards
This webinar will focus on the following key topics:
• Significant new material inventions in lithium ion and other advanced battery chemistries in the US
• Two primary issues or “gaps” in getting these technologies to the market
– generating samples for investors, customers and internal engineering evaluation and optimization
– building a battery factory and gaining product and quality system approval (a huge undertaking)
• Polaris Battery Labs Capability Overview for samples and commercialization
• Partner Profile; Carestream Heath as a contract coating partner to reduce time-to-market and risks
