Solid-state

China's EHang has completed what it calls the world's first solid-state battery test in a pilotless passenger-carrying eVTOL. With nearly 500 Wh/kg of energy density, the solid-state battery contributes to a serious boost in endurance.

Factorial has been working on lithium-metal quasi-solid-state technology for over a decade, aiming to create an energy-dense battery that costs the equivalent of lithium-ion units. This month, it's sent out its first B-samples to Mercedes-Benz.

IM motors has decided that semi solid-state batteries are ready for prime time. In an omen of what Western automakers will need to contend with, it's now launched a futuristic luxury coupe with a next-gen battery pack and crab-walking capability.

Earlier this year, we introduced solid-state micro-speaker technology from California's xMEMS Labs that's designed to replace coil-based drivers in wearable audio products. Now the company is aiming for satisfying low end with the Cypress speaker.

Back in late 2022, Frore Systems emerged from stealth with two solid-state active cooling chips for computers called the AirJet Pro and AirJet Mini. Now Chinese multinational Zotac has announced the rollout of the first mini-PC built around the latter.

Back in April, xMEMS Labs revealed solid-state technology aimed at replacing coil-based speakers in audio wearables like in-ear monitors. Now the company has partnered with Creative Technology for an upcoming pair of true-wireless earphones.

Researchers have developed a groundbreaking method of storing and handling valuable biological materials that removes the limitations of refrigerated storage. The novel method has potential applications in healthcare and scientific research.

Stromer is hard at work on a solid state battery pack that could lower ebike charging times drastically. The pack could charge 10 times faster than traditional lithium batteries, allowing riders to get back in the saddle in minutes, not hours.

Oak Ridge National Laboratory has come up with a small tweak to the way that a type of solid-state battery is made, which eliminates defects in the electrolyte film, opening the way to safer and more efficient batteries.

xMEMS Labs is aiming to replace century-old coil-based speaker technology with silicon-based microspeakers, and has launched three Solid-State Fidelity solutions for use in upcoming true-wireless earphones, in-ear monitors and digital hearing aids.

A new solid-state battery design points to a new solution to the technology's stability issues, with researchers developing a novel electrode material that retains its volume throughout charging to enable the battery to endure hundreds of cycles.

Gases used as refrigerants in cooling systems can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a solid-state material as a refrigerant.
