General Motors - Inverted U Battery Cell Design Jellyroll-style battery stack geometry is nothing new. French physicist Gaston Plante designed the first rechargeable battery using this design ...

This unit serves as a supplementary power source to the fuel cell stack. Like a large battery, the ultracapacitor recovers and stores energy generated during deceleration and braking. It uses this ...

General Motors is investigating a new way of configuring prismatic battery cells to ... The inverted "U" stack also increases thermal delay time within the cell, causing heat to spread more ...

“Most of our recent work has been on lithium hybrid redox flow batteries — part battery, part flow cell — which makes a much more energy dense battery with a smaller footprint,” says Stevenso ...
