Lithium-ion batteries power much of the modern world, so improvements in performance can benefit a wide range of devices. Scientists in Japan tinkering with battery components have come up with a new ingredient they say can offer greater safety and an … Continue reading High-voltage electrolyte gives lithium-ion batteries a boost
At 50 percent smaller by volume than a typical lithium-ion battery, Samsung’s prototype solid-state pouch cells could enable 500-mile electric car ranges and cycle lives over 1,000 charges in a much safer package.Continue ReadingCategory: Energy, Scien… Continue reading Samsung reveals long-range, solid-state, EV battery prototype
Battery researchers place a lot of focus on making the devices safer, and scientists at the University of California San Diego (UCSD) are reporting a promising advance in this area. The team’s newly developed safety feature acts as a “spillway” in lith… Continue reading Modified battery separator acts as a “spillway” to prevent fires
Today’s lithium batteries consist of a cathode, an anode, and a liquid electrolyte that carries lithium ions back and forth between them as it charges and discharges. Lately, scientists have been looking into what more solid versions of an electrolyte … Continue reading Semi-solid “cupcake” electrolyte keeps lithium-sulfur battery ticking
Electric vehicle batteries have improved considerably in recent years, but their limited ability to store energy still keeps many people from giving up their gas-burning cars. That may be about to change, though, as a new anode material is said to offe… Continue reading New battery material claimed to offer radical boost in capacity
It’s hard to imagine a world without the lithium-ion batteries that power today’s laptops and mobile devices, but the technology does have its limits. One way scientists are working to break a bottleneck of energy density and greatly extend the battery… Continue reading Ultrasound-equipped battery prevents potential fires with sound waves
Lithium-ion batteries are notorious for spontaneously combusting, with seemingly so many ways that it can be triggered. While they are a compact and relatively affordable rechargeable battery for hobbyists, damage to the batteries can be dangerous and lead to fires.
Several engineers from the University of Illinois have developed a …read more
We’ve all gotten pretty adept at 3D printing keychains and enclosures. Some people can even 3D print circuit boards to an extent. But the real goal is a Star Trek-style replicator that just pushes out finished products. Printing different components would be a key technology and unless you want to …read more
The 18650 cell has become a ubiquitous standard in the lithium battery world. From power drills to early Tesla vehicles, these compact cells power all manner of portable devices. A particularly common use is in laptop batteries, where they’re often built into a pack using the Smart Battery System. This …read more
Here’s a tip for all you retrocomputing enthusiasts or even anyone with an old computer in the garage. Go remove the battery. Yes, that old mid-90s desktop has a battery inside for the real-time clock, and it’s a ticking time bomb. Batteries leak, and they’ll spew goo all over the circuit board, irreparably damaging your piece of electronic nostalgia. This goes for all electronics, too: that badge collection is going to be a pile of broken fiberglass in a decade. Remove your batteries now.
While lithium cells soldered to a motherboard will leak, now there might be a new technology …read more
