Berkeley Lab scientists create microcapacitors with ultrahigh energy and power density. The microcapacitors are made with engineered thin films of hafnium oxide and zirconium oxide. The technology ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal stresses. Soft switching employs more sophisticated design to reduce stresses and ...

The first examples of the cells have just been shipped to the manufacturer of pseudo satellites, and Amprius says they could also be used to power larger eVTOL aircraft. The latest electric batteries ...
