Electric vehicles (EVs) and green energy sources rely heavily on batteries to store electricity. Currently, more than 75 percent of the world’s energy storage depends on batteries that contain lithium, an expensive mineral that’s subject to volatile pricing. Lithium-ion (Li-ion) batteries themselves can be volatile, too, because they use a…

The rhythms of real-world driving enable EV batteries to live far beyond the predictions of laboratory tests, according to a new study from Stanford University. The report, published in December in Nature Energy, suggests that EV batteries could last 38 percent longer than previous lab-based estimates. That means drivers could…

While the world is waiting—and waiting—for the giant leap to solid-state batteries, a nimble step to silicon anode cells is well underway. That transitional stage includes a key ingredient made in the U.S., not China. Sionic Energy today announced a robust battery that replaces graphite entirely, with a 100 percent…

For years, proponents of deep sea mining have eyed small metallic lumps that line much of the ocean floor. These polymetallic nodules are rich in manganese, nickel, and cobalt, all used in lithium-ion batteries. But new research shows the nodules might already be a kind of battery—one that might be…

Implantable Batteries Run on the Body’s Oxygen

Computer & Information Technology

Nearly all implantable medical devices, such as pacemakers and neurostimulators, are limited by the capacity of their onboard batteries. To avoid the need for invasive surgery to replace these devices once their batteries run out, scientists have sought to develop implants that can derive power from the body. To that…

EV Design and Battery Tech Trim Back for Slimmer Times

Civil, Structural & Architecture

The champagne pop of a record 1.2 million EV sales in America in 2023 couldn’t fully cover a shortage of fizz: Suddenly slowing consumer demand. Automakers walking back ambitious EV production plans. A shaky public charging infrastructure that’s keeping potential buyers on the sidelines. When Elon Musk himself sounds pessimistic…

Solid-State EV Batteries Now Face “Production Hell”

Electrical, Electronics & Instrumentation, Mechanical, Production & Manufacturing

Recent solid-state battery announcements by Volkswagen and QuantumScape are raising hopes in the electric vehicle market, but automotive battery experts are warning that the road to widespread, solid-state success is still a long and arduous one. A single breakthrough, as if from above, is not likely to turn the whole…
