As a sustainable power source for automobiles, PEFC (Polymer Electrolyte Fuel Cells) have been investigated for further improvement of their durability. In general, the degradation of PEFCs is caused by various factors under operation. Thus, a comprehensive analysis is required to understand these important degradation factors.
This presentation will share evaluation by multi-analysis method of degraded PEFCs after their cycling. It was found that Si was contaminated in the cathode catalyst layer, and that Pt particles were enlarged in the cathode catalyst layer near the cathode gas outlet area. In addition, it was found that the degradation of the ionomer was more likely to occur near the cathode gas inlet area.
This webinar will focus on the following key topics:
• Polymer electrolyte fuel cells (PEFCs)
• Durability test
• Ionomer
• Comprehensive degradation analysis

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 risksPresenter

Solid Electrolytes and Bulk Scale Solid-State Batteries
Recently, the push to move beyond Li – ion battery technology has grown. Several advanced battery technologies & chemistries have been identified as promising candidates including i) solid-state batteries with Li metal anode, ii) Li – S chemistries, iii) Li – air(oxygen), and iv) flow batteries. Although an engineered solution using liquids may be possible for some of these options, a solid electrolyte is an enabling technology for each of these beyond Li – ion alternatives. This webinar will introduce the operating principles of each of these cell technologies and solid electrolytes will be discussed in this context. The requirements of a solid electrolyte will be outlined & several state of the art solid electrolytes will be compared. Recent technical progress towards the fabrication of solid-state batteries will be reviewed. Finally, an overview of market applications for solid-state will be presented.
This webinar will focus on the following key topics:

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

Battery Selection Tutorial Course 1/3: Selecting your Cell and Cell Manufacturer(s)
After designing your product, you need to ensure the battery with which you are operating it will ensure the right performance and lifetime. When deciding this, narrowing down which chemistry (e.g. Li-ion, lithium primary, NiMH, etc.) best fits your product and which form factor are some of the first steps. Choosing a cell design (high-power vs. high-energy, for example) is another step and finally, finding the right cell manufacturer to fabricate your cells and packs. This webinar is the first in a three-part series on designing the right battery for your product. It will cover many of the key differences in chemistries, form factors, and cell designs and other best practices.
This webinar will focus on the following key topics:
• Choosing the right chemistry for your application
• Choosing the right form factor
• Choosing cell designs (e.g. high power vs. high-energy)Presenter
