A cyclic phosphate-based electrolyte for safe and high voltage lithium-ion batteries
In light of the ongoing shift toward renewable energy technologies and the growing number of Internet of Things (IoT) devices, researchers worldwide have been trying to develop batteries that can operate more efficiently and for longer periods of time. Lithium-ion...
Exploring the effects of exchange rate fluctuations on technological learning rates
When it comes to predicting the costs of new energy systems and technologies, researchers must consider learning rates, which are estimated measures of technological progress. In fact, technological advances are typically associated with higher technological...
Enhancing high-nickel layered oxide cathodes for lithium-ion batteries
Lithium-based batteries are used to power most existing electric vehicles, yet the amount of time they can keep a vehicle going before they need to be recharged is still somewhat limited. In the future, high-nickel layered oxide cathode materials could help to...
Gradient Li-rich oxide cathode particles for batteries with minimum oxygen release
Lithium-rich transition metal oxide (Li1+XM1-XO2) cathodes have potential for use in Li-ion batteries, powering electronic devices and electric vehicles. These cathodes have a high energy density, typically above 900 Wh kg-1, yet they currently also come with...
Using deep learning to predict parameters of batteries on electric vehicles
The batteries used to power electric vehicles have several key characterizing parameters, including voltage, temperature, and state of change (SOC). As battery faults are associated with abnormal fluctuations in these parameters, effectively predicting them is of...
Surface organometallic chemistry could open new paths for synthetic fuels and energy carriers
To convert hydrocarbons into fuel, the petrochemical industry currently relies primarily on heterogeneous catalysts, which in most cases contain active metal sites with poorly defined structures. In recent years, however, an area of study known as surface...
PixelGreen: A hybrid, green media wall for existing high-rise buildings
Researchers at Deakin University and the University of Hong Kong have recently designed a hybrid green architectural wall system for high-rise buildings that integrates a vertical micro-farm and a media screen. They presented this wall, called PixelGreen, in a paper...
A new water-splitting technique to generate clean hydrogen
Electrolytic hydrogen production entails the generation of hydrogen from water using electrical power, which should ideally come from renewable power sources such as sunlight and wind. Although this method of producing hydrogen could be a very promising solution for...
All-perovskite tandem solar cells with 24.8% efficiency
A team of researchers at Nanjing University in China and the University of Toronto in Canada have recently fabricated all-perovskite tandem solar cells (PSCs), a type of solar cell with a key perovskite structured component. These new solar cells, presented in a paper...
