While lithium-ion remains dominant, pressure is building for longer-duration storage, safer chemistries and more resilient supply chains in the face of AI-driven load growth, data center demand, wildfire risks and tightening domestic content rules. . The energy storage industry walked a bumpy road in 2025, but eyes are turning toward 2026's tech stack.

The short answer is yes, storage batteries can be recycled. However, the current landscape of battery recycling isn't the greatest with infrastructure severely lacking in the UK. . Recycling used lithium-ion batteries (and the devices that contain them) will help address emerging issues associated with the clean energy transition and prevent problems caused by inappropriate battery disposal. End-of-life lithium-ion batteries contain valuable critical minerals needed in the. . In their Joule paper “ A direct electrochemical Li recovery from spent Li-ion battery cathode for high-purity lithium hydroxide feedstock,” lead author Yuge Feng and colleagues reveal how they developed a new, cleaner, and more efficient electrochemical approach for recovering lithium. Take California's Moss Landing facility, where 4,600 Tesla Megapacks live out their. .
