Gold futures retreated Monday, sending prices to their lowest finish in more than a week as Treasury yields remained elevated and a leading dollar index firmed. “Gold’s weakness is not just due to the stronger dollar, but the rising yields, too,” said Fawad Razaqzada, technical analyst at Forex.com. “Together, these factors are proving to be […]

You may want to double-check the dimensions of the 18650 you’re targeting for a design—a built-in protection circuit could extend it past the standard size. Since the late 1990s, the 18650 lithium-ion rechargeable cell has been a common standard cell used in many devices and a host of applications. Like the ubiquitous AA, AAA, C, […]

A “high performing”, doughnut-shaped active material structure inside a lithium-sulphur battery has been developed by the Korea Advanced Institute of Science and Technology (KAIST). This lithium-sulphur (Li-S) battery has a higher energy density and lower production cost than a lithium-ion battery (LIB), according to KAIST. Therefore, it can be used in electric vehicles (EVs) that […]

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 combust if exposed to water — even […]

What is a lithium thionyl chloride battery? Under the broad category of primary lithium battery types, numerous types of primary (non-rechargeable) lithium battery chemistries are commercially-available that differ in their performance characteristics. The critical considerations are voltage, discharge current, service life and temperature range. LiCFX (poly carbon monofluoride) and LiMN02 (manganese dioxide) chemistries are commonly […]

A Korea Advanced Institute of Science and Technology (KAIST) research team developed a lithium-sulfur battery with a doughnut-shaped active material structure showing a record lifecycle of over 600 cycles (Advanced Science, “An Ultrahigh Capacity Graphite/Li2S Battery with Holey-Li2S Nanoarchitectures”). Having higher energy density and lower production cost than a lithium-ion battery (LIB), it can be […]

Many EV batteries may not last as long as consumers expect—especially if trends toward nickel-rich chemistries and fast-charging continue, an expert said at last week’s Battery Show. Asad Farid of Berenberg Bank told engineers at the show that many of the newer breed of batteries will last, on average, only about five years. “We think […]

Renewable energy resources – such as wind, water or solar solutions – hold great promise. They could provide energy while overcoming Africa’s infrastructural challenges. But this energy would still need to be stored. Lithium ion batteries might provide a solution. The Conversation Africa asked Bernard Jan Bladergroen about the challenges and opportunities. What is a […]

In his Ph.D. thesis, Alberto Berrueta has investigated the physical mechanisms that govern the functioning of lithium batteries and their influence on a battery that functions when connected to a renewable facility. He also explored the way in which these batteries degrade, and has proposed a new management system. “The installing of renewable energy sources […]

In the battle for battery virility, Hyper just launched HyperJuice. The company says it’s “the world’s most powerful USB-C battery pack” and the first to support the 100W USB-C Power Delivery 3.0 Profile. The battery is capable of 130W of total combined output when using the 100W (max) USB-C input / output jack, the 60W […]
