Sepion Technologies

We are pleased to announce our recent win securing $17.5 million in funding to build a cutting-edge lithium-ion battery separator manufacturing facility in West Sacramento’s Capitol Innovation District. Our advanced separator technology improves battery durability, energy density, and cost while dropping in with existing Li-ion manufacturing. Big thanks to the California Energy Commission, CALSTART, Berkeley Lab, New Energy Nexus, and YUNEV, LLC for their tenacity and vision in creating the PowerForward Program to expand California’s leadership in domestic battery supply chains. With these funds, Sepion aims to address the significant domestic supply shortage of battery separators. This project supports partnerships with local organizations to train a high-tech manufacturing workforce and reinforces California’s position as a leader in sustainable manufacturing. Onward with the electrify everything revolution! Read more here: https://lnkd.in/gFKuwW_P

We were pleased to participate in the PlugVolt Battery Seminar 2024 in San Jose last week. In our presentation, "Redefining the Role of the Separator in Battery Evolution," CTO Dr. Brian Sisk talked about the future of separators for Li-ion and Li-metal technologies, and how better separators can unlock value to help reduce the cost of EV batteries. We fielded lots of great questions, and look forward to continuing discussions about Sepion's innovations with many of our colleagues, customers and industry partners. www.sepiontechnologies.com #BatterySeminar2024 #batteries #separators #electricvehicles #emobility #EVs

Polyolefin separators interact with all major constituents within a Lithium cell – anode, cathode and electrolyte – and serve several critical functions including strong electrical insulation, good ionic conductivity, and high thermomechanical stability. Despite the many demands put on them, the separators deliver on everything at a very low cost. But the commodity nature of an incumbent separator makes it a “jack of all trades”, whereas functionalization of conventional base-layers with materials appropriate for today’s advanced batteries can allow them to do much more. Join us at the PlugVolt Battery Seminar 2024 in San Jose next week, where our CTO Dr. Brian Sisk will be addressing the topic of "Redefining the Role of the Separator in Battery Evolution". He’ll be discussing the science behind Sepion's ultra-thin, nanoengineered polymer coatings cast on commercially sourced base-layers, and how it enables adoption of next-gen. anodes such as Li-metal as well as sustainable, higher performance, and naturally Cobalt-free cathode materials such as LMO/LNMO/LMFP. Brian will also share an overview of how the separator coatings unlock several performance gains including increased energy density, superior wetting, lower moisture, transition metal blocking, and greater dimensional stability. We hope to see you there! https://bit.ly/3LlQ1SZ #BatterySeminar2024 #batteries #separators #emobility

Our Biz Dev VP Salil Soman will be attending Cambridge EnerTech's Advance Automotive Battery Conference in Strasbourg on Tuesday 14/5/24, and we're looking forward to hearing about all the latest trends in EV battery development, breakthrough technologies and market projections. Let us know if you'd like to meet up while he's in France. https://bit.ly/3wDpr3H #AABCEurope #batteries #emobility #sepion

Big news in EV battery safety! We are pleased to announce that by utilizing our proprietary AI-driven materials discovery platform, Sepion has developed a non-flammable liquid electrolyte that can greatly reduce the risk and severity of fires in EV batteries. With this achievement, we move closer to safely unlocking a 40% increase in range together with fast-charge capabilities for the next generation of EVs – accelerating their adoption worldwide. Our researchers subjected the newly discovered liquid electrolyte to flammability testing against standard commercial lithium-ion battery electrolytes, demonstrating its efficacy and safety features. Its flash point exceeded 70°C, and its self-extinguishing time (SET) was 25 times better than that of standard lithium-ion battery electrolytes. Thank you to our dedicated scientists and researchers for this significant milestone!

Happy Earth Day! Today, let's celebrate sustainability and the power of e-mobility to drive us towards a cleaner, greener future. Electric vehicles aren't just the way of the future; they're the key to reducing emissions and preserving our planet for generations to come. Together, we can drive change and make every day Earth Day! #sustainability #emobility #EVs #lithium #batteries #2024earthday

Exciting news from Sepion! 🚀 We're thrilled to announce that we've attained UN/DOT 38.3 safety certification for lithium-metal batteries utilizing our proprietary coated separator and electrolyte products. This milestone reaffirms our commitment to prioritizing safety in battery technology. Our patented lithium-metal cells have undergone extensive internal and external testing, consistently demonstrating exceptional abuse tolerance without sacrificing performance. This translates into higher energy density and faster charging, all while upholding stringent safety standards. At Sepion, we’re shaping the future of battery technology with greater design options for automotive manufacturers, empowering them to deliver safe and sustainable vehicles that meet the diverse needs of the next wave of EV customers. https://lnkd.in/gJCvdDxW #lithium #limetal #batteries #EVs #safety #certification #sepion

A recent survey from the McKinsey & Company Center for Future Mobility reveals how consumer attitudes about electric vehicle charging could influence the EV market. 42% of survey respondents cite charging speed as their most important consideration, with over 60% wanting charging times less than 30 minutes. This offers various new opportunities including encouraging transformations in fast charging like Sepion's coated separator and liquid electrolyte innovations that aim to bridge the gap between customer expectations and today's charging technology. https://mck.co/3vLc9BR #emobility #fastcharging #sepion

Being our own test subjects here in Orlando for the Cambridge EnerTech International Battery Seminar as Sepion CTO Brian Sisk and Biz Dev VP Salil Soman had to look hard for a DC fast-charger to quickly top-off their rental EV while prepping for Brian's presentation on "Overcoming Charge Anxiety"!   Along with reviewing current lithium-ion fast charge performance requirements and material-level characteristics, Brian addressed Sepion's separator and liquid electrolyte innovations that are targeted to make next generation Li-metal batteries achieve not only greater energy density but also deliver faster charging.   #lithium #fastcharge #floridabattery

Hope to see some of you at Cambridge EnerTech's International Battery Seminar next week in Orlando. Our CTO Brian Sisk will be speaking in the Lithium-ion Battery Development & Commercialization Track about "Overcoming Charge Anxiety and Meeting Customer Expectations with Energy Dense Lithium-Metal Batteries" on Friday, March 15, at 11:05am.
