Bonjour, Paris! It’s been an inspiring week at VivaTech 2026, where AESC showcased our pioneering zero-carbon solutions to tackle global grid bottlenecks amid the AI computing boom. Envision Founder & CEO Lei Zhang noted during the panel discussion that traditional grids can no longer keep pace with surging AI demand. To address this gap, we are launching the Mission Gobi project, which will deliver 5GW of AI data center capacity powered by 100% renewable energy across Gobi Desert regions over the next five years. At AESC, we turn this vision into action. As a global advanced battery leader, we advance the net-zero transition via our EV and BESS businesses, with a diverse team delivering operational excellence across Europe, the US, Asia and beyond.

Sodium-ion is becoming an important part of the next chapter in energy storage. It will not replace lithium-ion. Instead, the two technologies will complement each other across different applications. For sodium-ion, two fields stand out: 🖥️ AI Data Centers Strong high-rate discharge and inherent safety make sodium-ion a strong fit for fast-response backup power in 24/7 high-load AI infrastructure. ❄️☀️ Extreme Climates Stable performance in low and high temperature environments enables reliable energy storage deployment in harsh regions. At AESC, our sodium-ion battery products have officially rolled off the production line this year. We stay fully committed to battery innovation and keep exploring new possibilities for the future of energy storage. #AESC #AdvanceWithAESC #SodiumIonBattery #EnergyStorage #CleanEnergy #BatteryInnovation #AIDataCenters

This year, AESC's self-developed sodium-ion energy storage cells entered mass production. For over a decade, lithium-ion has anchored electrochemical energy storage. As deployment scales into more diverse climates and grid scenarios, the industry needs a complementary chemistry — not as a replacement, but as a partner. Sodium-ion is that partner. Abundant raw materials. Stable performance in extreme cold and heat. High-rate discharge with strong thermal safety. And — finally — production-ready. This is AESC's next chapter in battery innovation. #AESC #AdvanceWithAESC #SodiumIonBattery #EnergyStorage #BatteryInnovation

Exciting milestone to share! AESC has earned an A- climate change rating from CDP — the highest score of any global lithium battery manufacturer in the 2025 reporting cycle. As the global gold standard for corporate ESG performance, CDP assessed over 22,100 companies this year, with only around 10% securing an A- or higher. This recognition validates our robust carbon management and steady progress in battery decarbonization. As the world’s first battery maker to achieve carbon-neutral operations and launch carbon-neutral EV & energy storage batteries, AESC will keep leading the industry toward a low-carbon, sustainable future. #AESC #CDP #ClimateAction #SustainableBatteries #NetZero #EVBatteries #EnergyStorage #Decarbonization #ESG #CleanEnergy

This World Earth Day, we're not just talking about sustainability goals. We're celebrating our global team — the people who turn these goals into tangible action, every single day. At AESC, carbon reduction is never a top-down mandate. It's the daily work of every colleague, across R&D, manufacturing, project delivery, and the supply chain. We asked them one simple question: How much carbon does your work save for our planet? Swipe through to meet a few of them — and see the measurable impact their teams deliver, from a single plant's energy savings to multi-gigawatt-hour storage portfolios powering the energy transition. #AESC #WorldEarthDay2026 #AdvanceWithAESC #NetZero #SustainabilityInAction #BatteryInnovation #EnergyStorage #RenewableEnergy #CarbonReduction #CleanEnergyFuture #PeopleOfAESC

What if next-generation battery materials could be identified in minutes, not months? For decades, battery material development has depended on slow and costly trial-and-error methods. At AESC, we are rethinking that process with cutting-edge AI. Built on 68+ million chemical compounds, our in-house AI model rapidly identifies high-potential materials against critical performance metrics such as stability, efficiency, and application performance. By drastically reducing the time needed for material screening, we are accelerating R&D and advancing the next wave of battery innovation. #AESC #AdvanceWithAESC #BatteryInnovation #BatteryMaterials #SmartManufacturing
