Batteries Have Moving Parts


The race is on to make lithium-ion batteries safer, to increase the amount of energy that can be drawn out of these devices, and to reduce the time it takes to charge them up again. Transistors and other electronic components depend on the movement of electrons, which are effectively massless and dimensionless relative to the semiconductor, metal, and dopant atoms that surround them.

Making Batteries Denser And Safer


Battery technology is improving swiftly, driven by the rapidly rising demand for electric vehicles and the vast body of knowledge developed by the semiconductor industry. The market for electric vehicles (EVs) is on a fast upward trajectory, with global sales predicted to grow more than 12 times to more than 31 million vehicles. In fact, EVs will account for almost a third of new vehicle sal... » read more

Power/Performance Bits: Aug. 24


Low power AI Engineers at the Swiss Center for Electronics and Microtechnology (CSEM) designed an SoC for edge AI applications that can run on solar power or a small battery. The SoC consists of an ASIC chip with RISC-V processor developed at CSEM along with two tightly coupled machine-learning accelerators: one for face detection, for example, and one for classification. The first is a bin... » read more

Room-temp superconductivity Researchers at the University of Rochester, University of Nevada Las Vegas, and Intel created a material with superconducting properties at room temperature, the first time this has been observed. The researchers combined hydrogen with carbon and sulfur to photochemically synthesize simple organic-derived carbonaceous sulfur hydride in a diamond anvil cell, which... » read more

Power/Performance Bits: Sept. 9


Smaller, cheaper integrated photonics Researchers from the University of California Santa Barbara, California Institute of Technology (Caltech), and Ecole Polytechnique Fédérale de Lausanne (EPFL) developed a way to integrate an optical frequency comb on a silicon photonic chip. Optical frequency combs are collections of equally spaced frequencies of laser light (so called because when pl... » read more

The Other Storage Race


Tesla's push to extend the life of lithium ion batteries used in cars by repurposing them for less-intensive applications could have a major impact on the business model for a whole slew of other markets. As anyone with a smartphone knows, batteries degrade over time. A new phone holds a charge longer than one that has been in use for several years, but in the case of a smartphone that's gen... » read more

Power/Performance Bits: Nov. 19


Quantum communications chip Researchers at Nanyang Technological University, Australian National University, A∗STAR, University of Science and Technology of China, Singapore University of Technology and Design, Sun Yat-sen University, Beijing University of Posts and Telecommunications, and National University of Singapore built an integrated silicon photonic chip capable of performing quantu... » read more

System Bits: Oct. 1


Jumping the gap in microchips A quasi-particle that travels along the interface of a metal and dielectric material may be the solution to problems caused by shrinking electronic components, according to an international team of engineers. "Microelectronic chips are ubiquitous today," said Akhlesh Lakhtakia, Evan Pugh University Professor and Charles Godfrey Binder Professor of Engineering S... » read more

System Bits: Sept. 17


Quantum computing R&D in Germany IBM is teaming with the Fraunhofer Society for research and development of quantum computing technology, backed by the German government, which is providing €650 million (about $715.4 million) in funding over two years for the program. IBM has agreed to install a Q System One system at one of its facilities in Germany for the program. The system has 20... » read more
