Wow, I'm sure we all saw this news yesterday. Quite a significant move. I've had a big interest in ultracpacitors since working to recruit for Skelton Technologies, a great Estonian manufacturer.
Tesla are to buy Maxwell Technologies for $218m. The combination of their Ultracapacitors, and dry electrode coating technology could lead to higher energy density and lower manufacturing costs. Both key advantages for any EV OEM, where Tesla already holds an advantage. I'm no Tesla Fan Boy, but they keep confounding critics and out-performing their rivals, on and off the road. Sometimes they even make a profit!! It's fun to watch, and with out doubt, they have, and continue to push the game forward.
Why do we care? Maxwell Technologies is all about batteries, with a specific focus on dry electrode manufacturing technology that it has been pairing with ultracapacitors. Dry electrodes represent a critical step in the journey towards solid-state batteries, while ultracapacitors have long held the promise of ultrafast charging, if a few key challenges can be overcome. Tesla moving in so boldly with a full acquisition deal hints at the prospect of a breakthrough in battery technology that has Tesla excited enough to dive in.
