    Why Battery Material Qualification Takes Years | Dr Stuart Johnson | The SP Show Ep. 2

    In Episode 2 of The SP Show, I sit down with Dr. Stuart Johnson, CEO of Solve Process, to unpack one of the battery industry’s most misunderstood realities: why battery materials take years to qualify, where timelines slip, and what kills scale-up programs in practice. With more than 30 years of experience in process engineering, Stuart breaks down the technical and commercial realities behind battery development in simple language. We cover how lithium-ion batteries work, what each component actually does, why qualification can take years, where startups get caught out, and how different chemistries may fit across the market over the next decade. This is not a hype-driven conversation. It is a grounded discussion about how things actually get built in the battery value chain, what goes wrong, what gets missed, and what experienced operators have learned the hard way. If you work in batteries, advanced materials, scale-up, manufacturing, or industrial deep tech, this episode will give you a much clearer view of what it actually takes to move from idea to execution. Watch, share, and subscribe for more real conversations across the battery value chain. #sripopuri Host of 'The SP Show' Podcast Founder of Battery Consulting Partners Battery Vault Newsletter LinkedIn: [https://www.linkedin.com/in/srinivas-popuri-ph-d/] Twitter: [https://x.com/Srinivasrpopuri] #Stuartjohnson Process Engineering Expert Founder & Director at Solve Process Ltd LinkedIn: [https://www.linkedin.com/in/stuart-johnson-18a0711a/] Read Battery Vault Newsletter Substack: [https://batteryvault.substack.com] LinkedIn: [https://www.linkedin.com/company/batteryvault/] Instagram: [https://www.instagram.com/batteryvaultt/] Battery Consulting Partners [https://batteryconsultingpartners.com/about-us/] Listen to 'The SP Show' Podcast on Spotify [https://open.spotify.com/show/1U9HrDjwEvPYSuA7w5X6Gy] Listen to 'The SP Show' Podcast on Apple Podcasts [https://podcasts.apple.com/us/podcast/the-sp-show/id1883846105] #sripopuri #thespshow #battery #gigafactory #batteryindustry #energystorage #batterymaterials #supplychain #ai #china #scaleup #manufacturing #engineering #energystorage #electricvehicles #processengineering
