"yes most people use gadgets such as tablets, media players etc. every day. It's always nice to see a long lasting battery."
Shehan, such technologies are yet to be developed. As of now most of such gadgets cells are in range of 1800-2500mAh. Iof they are able to come up with 5000mAh range cells, it may last long. But I don't know, what's the reason still manufacturers are not looking to such aspects.
On second thought, the fact that there a 'terminator polymer' with conducting properties of its own is yet to be developed still means that it may be a while before large scale use of the new batteries is witnessed. This is because the creation of the current polymer developed by the Stanford team also includes additional costs for the addition of carbon nanoparticles, a fact that will definitely make them more expensive.
For those of us who work in the design of electronic products, this development is ground breaking and could change or overhaul most of the designs that are currently in the market since it answers one of the biggest headaches in this field; how to ensure lifetime power supply is provided for special components of the device.
"At times I tend to think that battery manufacturers have not invested much time and money on research and development. A battery manufacturer surely knows in an out of the batteries they manufacture and the materials used."
Shehan, how does it matter? Everybody is using the same cells with same technology and material.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
