A new fabrication technique could allow solid-state automotive lithium-ion batteries to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes.
Individuals who have owned a smartphone for more than a year would probably know that the integrated lithium (Li)-ion battery does not retain as much charge as it did when the phone was new.
Around the world there are currently more than 18 billion internet-connected mobile devices. In the next 10 years, anticipated growth in the Internet of Things (IoT) and in machine-type communication in general, will lead to a world of hundreds of billions of data-connected objects. Such growth poses two very challenging problems:
Nanoengineers from the University of California, San Diego (UC San Diego) have gained a new fundamental insight for designing lithium metal batteries that work well at very low temperatures; specifically, the weaker the electrolyte binds to lithium ions, the better.
At the heart of most electronics today are rechargeable lithium-ion batteries (LIBs). But their energy storage capacities are not enough for large-scale energy storage systems (ESSs). Lithium-sulfur batteries (LSBs) could be useful in such a scenario due to their higher theoretical energy storage capacity. They could even replace LIBs in other applications like drones, given their light weight and lower cost.
The U.S. pulp and paper industry uses large quantities of water to produce cellulose pulp from trees. The water leaving the pulping process contains a number of organic byproducts and inorganic chemicals. To reuse the water and the chemicals, paper mills rely on steam-fed evaporators that boil up the water and separate it from the chemicals.
A long-cherished dream of materials researchers is a solar cell that converts sunlight into electrical energy as efficiently as silicon, but that can be easily and inexpensively fabricated from abundant materials. Scientists at the Helmholtz-Zentrum Berlin have now come a step closer to achieving this.
A group of researchers from Florida State University (FSU) has devised a new method to make use of a material contained in plants to develop safer batteries.
Scientists from the University of Illinois Chicago have found a new method for conversion of methane in natural gas—the fuel used to cook food, heat homes, and produce electricity —into liquid methanol at room temperature.
Scientists have demonstrated that modifying the topmost layer of atoms on the surface of electrodes can have a remarkable impact on the activity of solar water splitting.
