All-Solid-State Batteries: Substantial Deterioration of ASSBs Can Occur After High-Temperature Storage


New technical paper titled "Detrimental effect of high-temperature storage on sulfide-based all-solid-state batteries" was just published by researchers at Seoul National University, National Synchrotron Radiation Research Center (Taiwan), and Battery Material Lab at the Samsung Advanced Institute of Technology. According to this AIP article, "The team found storage as low as 70 degrees Cels... » read more

SolidPAC is an interactive battery-on-demand energy density estimator for solid-state batteries


Summary "Solid-state batteries hold the promise to be highly impactful next-generation technologies for high-energy and -power-density rechargeable battery applications. It is crucial to identify the metrics that an emerging battery technology should fulfill to achieve parity with conventional Li-ion batteries, primarily in terms of energy density. However, limited approaches exist today to as... » read more

Manufacturing Bits: Feb. 7


Design tools for solid-state batteries Oak Ridge National Laboratory has devised a new tool designed to accelerate the development of energy-dense solid-state batteries. The tool, called the Solid-State Battery Performance Analyzer and Calculator (SolidPAC), enables researchers to assess the impact of battery designs and choice of cell components for solid-state batteries. It can be used to... » read more

New Ways To Improve Batteries


Researchers around the world are racing to develop more efficient, denser, and safer battery technology, and they are reaching far beyond where research has gone before. Much of this is being driven by concern over exhaust from internal combustion engines, which are responsible for a significant portion of global CO2 emissions. Nearly all carmakers today have announced plans to develop batte... » read more

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

The Battery Problem


The fires sweeping the West Coast of the United States point to the need for a whole different way of managing power on both a macro and a micro level. Since the millennium, the power demand from data centers and from mobile devices has been climbing steadily. There are roughly 7.8 billion people on the planet, up from 6.115 billion people in 2000, according to the World Bank. Many of them o... » read more

5 Major Shifts In Automotive


Much of the automotive industry has begun repositioning and retrenching over the past few months, pushing back the projected rollout for fully autonomous vehicles and changing direction on power sources and technology used in the next-generation of electric vehicles. Taken together, these shifts mark a significant departure for traditional automakers, which find themselves playing catch-up t... » read more

Power/Performance Bits: March 21


Tiny redox flow batteries for chips Researchers at ETH Zurich and IBM Research Zurich built a tiny redox flow battery capable of both powering and cooling stacks of chips. In a flow battery, an electrochemical reaction is used to produce electricity out of two liquid electrolytes, which are pumped to the battery cell from outside via a closed electrolyte loop. Such batteries are usually u... » read more

Power/Performance Bits: Aug. 23


Connecting implanted devices University of Washington researchers developed a new method for communication between devices such as brain implants, contact lenses, credit cards and smaller wearable electronics with other devices such as smartphones and watches. Using only reflections, an interscatter system requires no specialized equipment, relying solely on mobile devices to generate Wi-... » read more
