A lot of undergraduates ask me "how do I learn more about batteries" so I decided to write my answer up: chang-lab.notion.site/How-To-Become-…

*Metal decarbonization* is essential for deep decarbonization. Electrolysis is an elegant solution and is now being pursued for decarbonizing ironmaking and other industrial processes. However, aluminum is already electrolytic and is still stubbornly CO2 intense. Why? 🧵(1/19)
