    Was Goodenough’s 3x Li-ion breakthrough research good enough?

    By Patrick Mannion | April 14, 2017

    John Goodenough (The University of Texas at Austin).

    Was it all too good to be true? It made for a great story: The 92-year-old inventor of the first lithium-ion battery was at it again. This time with new research on a chemistry that could store up to three times as much energy, charge in minutes instead of hours, and operate higher voltages and at much colder temperatures, down to -20˚C.

      Europe’s enthusiasm for the clean environment and energy efficiency apparently makes the electric bicycles or e-bikes a poster child of the shift from mechanical to electronic control systems. However, what’s new in the e-bike story is that China is now only issuing new licenses for e-bikes while putting an end to the permits for gas-powered bicycles.

        Guest Blog: Calculating the accuracy of a battery fuel gauge

        February 2, 2017

        battery fuel gauge

        By Onyx Ahiakwo

        A battery fuel gauge obtains data from the battery to determine how much juice is left. Do not misconstrue gauging accuracy for measurement accuracy. A gauge’s ability to accurately report state of charge (SOC) and predict remaining battery capacity depends on measurements including voltage (‘V’), current (‘I’) and battery temperature (‘T’).

          From smartphones to automobiles and the electric grid, energy storage is becoming more critical. For mobile devices, the need is clear for safe, longer-lasting, energy-dense chemistries. For automobiles, the move to hybrid, electric, and autonomous vehicles has increased the bounty to be had for denser and lighter storage.

            How to profit from ‘The Year of The Battery’

            December 30, 2016

            Battery manufacturers – and would-be competitors – are experimenting with all manner of alternatives these days – from nanotechnology to Prussian Blue dye (used to color fabric, paints, etc.) to make cheaper, more powerful, longer lasting storage devices.

            The same forces are attracting massive investments in lithium battery technology, a market which is expected to grow from $17.5 billion in 2013 to $76.4 billion in 2020.

              Supercapacitor battery charges in seconds, lasts a week

              December 30, 2016

              .

              Breakthroughs in battery technology are becoming increasingly common these days, a manifestation of years of multi-billion dollar R&D investments focused on advanced materials science in hot pursuit of a compact, renewable energy sources by the world’s automobile and electronics makers.

              The latest advance is a battery that charges in seconds and holds a charge for a week, a University of Central Florida development that could one day replace lithium-ion batteries.The new battery is highly flexible and measures a fraction of the size of a lithium-ion battery.

                Toyota’s on track with new lithium battery technology

                December 29, 2016

                History of lithium superionic conductors – PhysOrg

                Toyota and the Tokyo Institute of Technology and High Energy Accelerator Research Organization (KEK) have reported a major advance in battery technology, in the form of new lithium-based superionic, solid-state, conductor materials.

                Toyota’s technology will allow the company to test various materials and battery structures, which is expected to be the basis of an improved electric vehicle in the next several years.

                  Spontaneous combustion hints at limits of Li-ion tech

                   

                  Forget snakes in planes, and creepy clowns; the spontaneous combustion problem with Samsung’s Note 7 mobile phone has spooked an entire industry.

                  After replacement phones ignited, engineers still can’t say for sure if the smoke bomb effect is the result of a battery flaw or due to a circuit design bug, possibly in the phone’s processor. As a result, Samsung has ditched its popular Note 7 and recalled all units.
