Li-ion batteries are everywhere powering all sorts of devices from e-cigarettes to smartphones computers and electric cars.
But, do we understand how Li-ion batteries fail ?
Tests have showed that failure in a Li-ion battery cell can cause a potentially catastrophic chain reaction and has been attributed as the cause of a number of plane crashes in recent years.
Millions of Li-ion batteries are manufactured every year and understanding what happens when they fail is key to improving their design. In a study published in Nature Communications, scientists believe they now have better insight into how the failure happens.
Paul Shearing from University College London (UCL) said “This new technique will provide a capability for evaluating different batteries, and how they age, degrade and fail”
Using a combination of high-speed X-ray tomography, radiography and thermal imaging, Shearing and a team were able to describe how overheating causes gas pockets to form inside the battery thus deforming its inner layers.
Overheating can happen due to electrical or mechanical abuse or the presence of an external heat source for example failure of adjacent cell in a larger battery pack, said Shearing.
“Depending on the cell design, there are a range of critical temperatures which, when reached, will trigger further exothermic events, which also generate heat,”
“Once the rate of heat generation exceeds the rate of heat dissipation into the environment, the temperature of the cell starts to rise, thereafter a sequence of detrimental events propagates in a process known as thermal runaway.”
Thankfully Li-ion battery problems are very rare. Get in touch to learn more about enterprise mobility….batteries included !
When you see the term “intrinsic safety” or a description of a mobile computer, tablet laptop or smartphone as “intrinsically safe” followed by a string acronyms – do you have any idea what it all means?
Intrinsic safety is a requirement that may be applicable to devices that are being operated in areas with flammable gases combustible dusts ignitable fibers or liquids. The device carrying the description is deemed to have been made in such a way as to be incapable of igniting these.
Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy available for ignition. In signal and control circuits that can operate with low currents and voltages, the intrinsic safety approach simplifies circuits and reduces installation cost over other protection methods.
Getting to grips with intrinsic safety regulations can be a tough assignment as the numbers of intrinsically safe rugged mobile devices continues to increase and the regulations are as complex as ever.
Areas with dangerous concentrations of flammable gases or dust are found in a wide variety of applications including mining and process manufacturing industries such as petrochemical refining. Plant maintenance process monitoring and asset management are popular applications. As with non IS zones improving workflow productivity and effectiveness are considered fundamental reasons to undertake project.
All devices that are to be used in an areas zoned as hazardous must carry the correct compliance certification for use in that area. Lab based certification allows a device to be used only in the area it is approved for. It is therefore important to understand which areas in your organisation should be treated in this way as it is not a case that “any rating will do”.
In the EU the standard for intrinsic safety certification is around the ATEX directive. In North America Underwriters Laboratories (UL) and in Canada the Canadian Standards Association. In many other countries around the world the IECEx standards are followed. Standards agencies do engage in harmonization activities so that intrinsically safe equipment manufactured in one country might be approved for use in another without expensive re-testing and documentation. But at this point a device certified for use in Europe may not be approved for use in the USA and vice versa.
Productivity improvements are often the key driver to implementing enterprise mobility solutions for organisations who have intrinsically safe areas. Making sure the most suitable devices are specified for use inside and outside these areas is key to operational safety and project success.

If you could not make it to Facilities Management show in Birmingham today here is the presentation we did with Hannah from SOTI “So What is Unified Endpoint Management”
xTablet T1600 weighs in at 1.23 kg and is part of a new breed of of large screen road warrior rugged tablet designs that are fashionably thin and light, run Windows 8.1, use capacitive multi touch and offer adequate on-board I/O. But are are much tougher and better suited for harsh business operational environments than the generally fragile thin consumer tablets. At last the blue collar rugged tablet to replace your laptop .. really !
The Large Screen Road Warrior Rugged Tablet T1600 employs an ultra-low voltage U-Series “Haswell” Intel 4th generation i5 processor. The dual-core i5-4200U runs at a base speed of 1.6GHz, with turbo boost speeds up to 2.6GHz. That appears to be a good match to the 45.8 watt-hour battery for a 7 hour estimated battery life.
With a diagonal screen size of 11.6 inches, the xTablet T1600 offers more display real estate than any other we have seen at this price point. In terms of usable area that’s almost a third more than that of an iPad Air, and 2.7 times as much as a typical 7-inch tablet. For a Windows based tablet that can make all the difference especially when wearing gloves on or when using the classic Windows desktop and software with all its small controls, checkboxes pulldowns and sliders.
The 1366 x 768 pixel resolution is a good match for this size display. The T1600 has 10-point capacitive multi-touch that MobileDemand claim can handle rain drops and use with gloves. Alternatively use the metal mesh tip stylus.
The T1600’s display offers 400 nits brightness which is about twice that of your average laptop, making it very vibrant indoors and likely adequate for outdoor use as well. Since brighter backlights draw more power, the T1600 uses its light sensor to automatically adjust screen brightness, with settings configurable via a special brightness level setup panel. A 800 nit Hi-Brite version is also available.
For wired connectivity, the T1600 offers two native high-speed full-size USB 3.0 ports, a combo in/out audio jack, and a docking connector, with RS232 and USB available via the optional dock. T1600 also has an expansion connector that can accommodate various modules.
For wireless dual-band 802.11ac WiFi via an Intel Wireless AC7260 module that also provides Class 1 Bluetooth version 4. Optional 4G LTE WWAN.
Large Screen Road Warrior Rugged Tablet includes options such as GPS and either an HF RFID reader or a 1D/2D scanner. There’s a 5mp rear-facing auto-focus camera in addition to the standard 2.0mp front-facing webcam. Along with ambient light, the tablet has a G-sensor as well as a gyroscope and e-compass.
Vehicle and office docks are available. The vehicle dock has a lock option, 75mm and 100mm VESA pattern for mounting, optional keyboard mounting with an AMPS pattern, and provides Ethernet, two USB 2.0 and USB 3.0 ports each, HDMI, RS232 serial, and SMA connectors for external WWAN and GPS antenna. The office dock has the same connectivity minus the SMA connectors.
While the xTablet T1600 is around 2 cm thick ruggedness is impressive. The tablet can survive 3-foot drops, sealing is to IP65 although with the standard back-strap it is easy to carry.
Find out how the Large Screen Road Warrior Rugged Tablet T1600 can be the rugged Windows tablet to replace your laptop.
