In this podcast, Eli Paster, CEO of Polyjoule, discussed polymer-based battery technology and how it differs from conventional metal-based batteries. Eli explained that Polyjoule uses conductive polymers instead of lithium, nickel, cobalt, lead, or sodium, synthesizing its own conductive polymers from abundant hydrocarbon feedstocks. Eli detailed the safety advantages of polymer-based batteries, including the inability to enter thermal runaway, and demonstrated this by cutting open a cell and applying a blowtorch for five minutes with no fire. Sean and Eli explored potential applications in residential energy storage, building codes, and the possibility of Polyjoule batteries being rated as firewalls.   Topics Covered: Polymer-Based Battery Conductive Polymers Hydrocarbon Feedstock Monomers and Polymers Polyacetylene PVC = Polyvinyl Chloride Lithium-Ion Battery LFP = Lithium Iron Phosphate NMC = Lithium Nickel Manganese Cobalt Oxide NCA = Lithium Nickel Cobalt Aluminum Oxide Sodium-Ion Battery Solid-State Battery Lead Acid Battery Thermal Runaway Short Circuit Arc Flash Battery Separator Electrochemistry Anode and Cathode Electrolyte Prismatic Cells Depth of Discharge Nominal Voltage Energy Density Round Trip Efficiency Schneider Electric UPS = Uninterruptible Power Supply UL 1973 UL 9540A IRC = International Residential Code NEC = National Electrical Code EV Auxiliary Battery Hybrid Battery Systems Hydrogen Fuel Cells   Reach out to Eli Paster here: LinkedIn: www.linkedin.com/in/elipaster Website: www.polyjoule.com Email: eli.paster@polyjoule.com   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean   solarsean.com/intro • solarsean.com/pvip • solarsean.com/pva • solarsean.com/pvds • solarsean.com/esip • solarsean.com/omat • solarsean.com/center • solarsean.com/sfev • solarsean.com/40hrpv • solarsean.com/pv2020nec • solarsean.com/18hrpv • solarsean.com/30hrpv • solarsean.com/ess • solarsean.com/10hress • solarsean.com/pvsiprep • solarsean.com/2hrbfc
