Irvine, California-based Enevate and Korea’s JR Energy Solution today announced that they’re going to jointly build a US battery cell electrode factory. Enevate and JR ES will tailor-make lithium-ion battery cell electrodes, including anodes and cathodes, and also provide a variety of electrode solutions for other customers. Enevate develops extreme fast charging EV battery technology, and JR Energy Solution (JR ES) designs and manufactures lithium-ion battery electrodes and cells. JR ES’s…

In the treatment of epilepsy and other neurological disorders, doctors will sometimes implant arrays of stimulating electrodes on the surface of a patient's brain. A new soft robotic system allows those electrodes to be placed far less invasively than ever before.The problem with implanting a whole group of linked electrodes lies in the fact that a relatively large portion of the skull has to be removed (and then replaced) in the process. Needless to say, it would be much better if just a small hole could suffice.With…

Tesla has poached a battery manufacturing expert to lead its dry electrode, which has been identified as one of the main bottlenecks for Tesla’s 4680 battery cell. When Tesla unveiled its 4680 battery cell at its Battery Day in 2020, the automaker highlighted several advancements that can significantly slash battery costs when bottled together. One of those main advancements was a dry electrode coating technology that Tesla obtained by acquiring Maxwell. This powder-into-film process is…

Bioelectronics is a burgeoning medical field, but it may have just taken a giant leap forward, with scientists successfully growing electrodes in living tissue, paving the way for fully integrated electronic circuits to treat neurological disorders.Scientists at Linköping, Lund and Gothenburg universities in Sweden have forged electrodes in living tissue using the body’s molecules to trigger them. The researchers are the first to successfully do this without the need for external signals or by modifying genes.In…

Scientists have produced a new high-capacity electrode material that barely changes in volume during the charge/discharge process. This unique feature can be leveraged to produce solid-state lithium-ion batteries with unprecedented durability.

Scientists tinkering with commonly used battery materials have come up with a way of tweaking their microstructures to improve energy density. The work points the way to electric vehicles that can travel farther on each charge, with the scientists hopeful further experiments can boost the performance even further.The work was carried out by scientists at the Skolkovo Institute of Science and Technology and focuses on one of the battery's two electrodes, called the cathode. In many lithium-ion batteries, this electrode is…

Scientists have demonstrated a new electrode material that could facilitate much faster charging for lithium batteries, and one that forms in a rather unusual way. The material actually adopts the optimal configuration of atoms through the charging process itself, in doing so taking on the form of a new material that allows for smoother transport of lithium ions.The work was carried out by researchers at the Boise State University and the University of California San Diego, who set out to address an Achilles' heel in…

Researchers at a New York-based institute said they have found a way to restore the sense of touch in a person who may have lost it due to an illness or injury. Scientists from the Feinstein Institutes for Medical Research said the procedure requires an electrode implant in the brain. Their path-breaking research can potentially help millions of people who live with paralysis and neuropathy (nerve damage). Imagine a person not being able to feel the touch of another person. The condition also creates difficulty in…

Scientists at the University of Buffalo experimenting with next-generation battery designs have demonstrated how magnetism might be used to bring a new level of precision to the way we monitor a battery's state of charge. The breakthrough hinges on a novel electrode design that induces shifts in a magnetic field as ions arrive and depart, which is said reveal battery life with a high degree of accuracy.The team's advance stems from its investigations in a field known as magneto-ionics, which refers to an ability to use…

As the source of power for electric cars and many other modes of clean transportation, improvements in battery technology stand to benefit vehicle performance in a number of important ways. This includes not just range figures but how well they can operate in colder climates, as new research detailing a promising sub-zero battery design demonstrates.Extreme temperatures that approach freezing can be quite problematic for lithium-ion batteries and lead to substantial power losses. In the context of electric vehicles, this…
