Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate. Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combu more
Scientists have created a new type of carbon that could make the batteries in our phones, tablet computers and laptops safer, more powerful, quicker to charge and longer lasting. An international team of researchers, led by Lancaster University and Jilin University in China, have announced the first more
Lithium-sulfur (Li-S) battery can be put into practice, if 20% of theoretical energy densities (2600 Wh/kg or 2800 Wh/L) can be achieved. Investigators have the ambition to reach the energy density of 500 Wh/kg in the near future. Xue-Ping Gao and co-workers, from Nankai University, tell us "Till no more
7 Up's original recipe contained Lithium - so what happens if you drop Lithium metal into modern 7 Up... The results surprised us. more
Lithium Ion is becoming the technology choice for HEV, PHEV, as well as many stationary applications. With such large battery packs it is important to understand how the individual cells and packs will behave in a variety of scenarios. One of the mai more
Lithium ion battery technology offers many advantages in portable power application but one major concern is safety – thermal runaway of the device in both normal and abusive situations. In the following article, it will be shown that by means of adi more
Rolling-element bearings are used for the precise guidance of moving parts. Frictional losses are extremely small because the bearings rest on rolling elements, enabling very heavy loads to be adsorbed. Rolling-element bearings may be lubricated with more
I wanted to display all the key points about each group of elements, in a way that was both clear and engaging for the pupils – as a consequence, the information presented is relatively basic, so that it’s accessible for as many of the year groups as possible. I also tried to include some informatio more
In this month’s Periodic Graphics in C&EN, we’re looking at the chemistry behind the recent news stories of lithium-ion batteries in some devices catching fire. You can see the full graphic over on the C&EN site. Also, for more lithium battery chemistry, head over to the recent RealTimeChem Week gra more
Today’s graphic takes a look at the research of Kent Griffith (@kentjgriffith), a PhD student from the University of Cambridge who’s currently looking into developing advanced lithium ion batteries to power our phones, laptops, and more. more
A novel lithium ion/oxygen hybrid battery system is proposed to use the advantages and minimize the disadvantages of both lithium-ion battery (LIB) and lithium-oxygen battery (LOB). In it, LOB-part plays the extended-range and high-power-output roles. While using the discharge-priority of LIB-part i more
Rational design of cathode host materials is of great significance in fulfilling high-efficiency sulfur electrochemistry as well as boosting the energy density of lithium-sulfur (Li-S) batteries. Herein, we developed a stringed “tube on cube” nanohybrids (CPZC) with ternarily hierarchical architectu more
Energies, Vol. 11, Pages 1669: Detection Method for Soft Internal Short Circuit in Lithium-Ion Battery Pack by Extracting Open Circuit Voltage of Faulted Cell Energies doi: 10.3390/en11071669 Authors: Minhwan Seo Taedong Goh Minjun Park Sang Woo Kim Early detection of internal s more
There is no doubt that fluorine industry has been one of the fastest developing and most promising chemical industries in China and China is the second largest economy in the world. Thus, fluorine chemicals, such as inorganic fluoride, refrigerant, fluor-polymer and fluor-intermediate four main sect more
China abounds in phosphorite and its output ranked the world’s first by 36.9% share of the global total in 2010. The vigorous downstream demand has fueled the rapid progress of Chinese phosphorous chemical industry in recent years, and the respective output of such traditional phosphorous chemical p more
STELLA CHEMIFA CORPORATION (STELLA CHEMIFA) is one of the leading producers of fluorine compounds in Japan. The company offers a range of market products and technology essential to the modern electronics industry such as liquid crystal panels, semiconductors, and lithium batteries. Its operations a more
