🚀 A New Approach to Solid-State Batteries 🚀 The dream of solid-state lithium-metal batteries has always been clear: longer range, ultra-fast charging, and enhanced safety. But the industry has faced two fundamental roadblocks: dendrites that cause failure and the challenge of manufacturing at scale. At Adden Energy, we’ve taken a different path. Instead of chasing the impossible – perfectly smooth, flawless separators – we’ve designed a battery that works with real-world materials, not against them. As Steve LeVine from The Information reports: “Real solid-state separators are never thin, dense and smooth,” says CEO William Fitzhugh. “No matter how you manufacture them, perfect films just aren’t possible.” Our solution? A three-layer sulfide separator that doesn’t need to be flawless – it just needs to be self-healing. When a dendrite forms, the middle sulfide layer expands like a balloon, filling gaps and stopping it in its tracks. 🔋 Charges as-fast-as-gas 🔋 1,000+ cycle life 🔋 Scalable manufacturing The future of solid-state batteries isn’t just about breakthroughs in the lab. It’s about making them manufacturable, reliable, and ready for the real world. That’s what we’re building at Adden Energy. #BatteryTech #ElectricVehicles #SolidStateBattery #Innovation #DeepTech #AddenEnergy Luhan Ye, Xin Li, Pu Zhang, Kimberly Branson, IN KIM, Fred Hu, Bernard Lupien, Laurie Menoud, Vinit Nijhawan (he/him), Brian Steinberg, Harvard University

Scaling next-generation battery technology isn’t just about breakthroughs in the lab - it’s about building the infrastructure to bring those breakthroughs to life. That’s why we’ve commissioned our R&D pilot line to accelerate the path from innovation to commercialization. This pilot line will help us refine manufacturing processes for dynamically stable, solid-state batteries, moving us closer to delivering higher energy density, faster charging, and enhanced safety for EVs. It’s a critical step in translating promising science into real-world impact. A huge shoutout to our team and partners who are making this possible! 💡⚡ Read more in our press release: https://xmrrwallet.com/cmx.plnkd.in/e5yNTnDe #SolidStateBatteries #EVRevolution #BatteryInnovation #Manufacturing #AddenEnergy

Breaking news! Adden Energy raises $15M Series A to scale its solid-state batteries for Electric Vehicle applications. The round was led by At One Ventures with participation by Primavera Capital Group, Rhapsody Venture Partners, and MassVentures. https://xmrrwallet.com/cmx.plnkd.in/geCNPYbP

Adden Energy is looking for a Mechanical Engineer to join our rapidly growing team! Ideal candidates have experience on roll-to-roll equipment for electrode coating. Check out our job post below to learn more.

Adden Energy welcomed our new Chief Product Officer, Dr Pu Zhang, to the team this week. Pu is one of the world's leading experts in sulfide solid-state battery cell design and processing. In this role, he will lead the transition of our extreme-fast-charging batteries from prototypes to full-scale automotive products. His joining is the most recent of a series of major milestones at Adden Energy as we gain momentum on our mission to make every vehicle electric. #climate #batteries #cleantech #startup

Material Design Principles for Solid-State Lithium-Metal Batteries with William Fitzhugh from Adden Energy. This talk will discuss design principles for solid-electrolyte to enable safe solid-state lithium-metal batteries. Particularly, safety features necessary for adoption by the automotive industry and how solid-state lithium-metal batteries can achieve these will be explored. Contrasting with liquid and/or semi-solid-state approaches, true all-solid-state batteries can safely deliver lithium-metal energy densities, fast charging, and stable cycling if the solid-electrolyte is properly designed. https://xmrrwallet.com/cmx.plnkd.in/eSCm8yVW #BatterySafetySummit #batterysafety
