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 ...

Solid-state batteries have the potential to make EVs far more affordable and practical, but their commercial development has a record of false promises that would make Tesla's full self-driving blush.

Battery maker LG Energy Solution is reportedly planning to stop using cathode materials from its sister company LG Chem for batteries supplied to Tesla.

Researchers at Australia's Monash University are close to solving one of the biggest challenges with eVTOL aircraft. The team's new lithium-sulfur battery tech is designed to deliver roughly twice the ...

Scientists have developed a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries by applying machine learning methods to battery performance data. The model ...

The partnership will focus on deployment of the Energy Vault B-Nest™, a proprietary hyperscale energy storage solution comprised of a multi-story battery system, for data center sites The B-Nest™ ...

Electrostatic capacitors are a key component in high-power pulse equipment, power transmission and transformation engineering, new energy vehicles, and 5G communication. Their capability for ultrafast ...

An E10X sodium-ion-powered microcar in yellow. E10X, a microcar made by the Chinese firm JAC Yiwei, a joint venture between JAC and Volkswagen, is one of the first mass-produced vehicles to be powered ...

For decades, fuel cell innovation has been guided by two main benchmarks: cost per kilowatt and stack durability. These remain important, especially in applications driven almost entirely by project ...

WASHINGTON — As the federal government reimagines American energy policy this year, support for projects hinges on a new metric — density. The concept of density in energy production echoes throughout ...
