  • The project was born out of collaboration between PARC (a XEROX company), Ford and the Oak Ridge National Laboratory (ORNL). Its name? “Co-extrusion for cost reduction of advanced high energy and power battery electrode manufacturing”. This project is funded by the US DOE Office of Energy Efficiency and Renewable Energy (EERE).

    PARC is developing inks and an appropriate CoEx hardware, able to co-extrude from a single nozzle two different materials within a print head and without mixing. ORNL will share its experience in energy storage (anode development, electrochemical performance optimization).

    "Our goal is to fabricate EV pouch cells that are higher in energy and power than conventional, with a path towards a reduction in dollar/kWh costs for electric vehicles" explain project principal investigator and PARC CoEx technical lead Dr. Corie Cobb.

    The project could reduce costs production by simultaneously depositing a full-thickness battery cathode, anode, and separator onto a current collector. As a result, this CoEx technique can be used to manufacture low-cost but more efficient rechargeable batteries, solar cells, superconductors, etc…

    Now, for the bad news: this exiting project has been announced three years ago…. To date, no update has been communicated. What are you up to guys?

  • Electric vehicles manufacturer Tesla is currently building its new massive battery factory in Reno (Nevada, USA). The firm has planned the grand opening celebration for July 29th, 2016.

    This date has been communicated by email to customers. Indeed, some lucky ones have won their place to the event by inducing more than five Model S sales through Tesla’s car referral program.

    Earlier in May, the construction was only 14% complete. But the event will be held in areas where the construction is complete. (click here to read media reports following early visits in March). The operation have even started with the assembly of the Powerwall which has been initiated in January.

    In the Gigafactory, Tesla will produce massive amounts of NCA batteries for its electric vehicles with the end goal being to drive the costs below the 200 $/kWh mark. The factory will also accelerate the manufacturing and assembly capability of the Model S, X and 3.

  • Researchers at MIT, Sheffield University and Tokyo Institute of Technology created a tiny ingestible origami robot, able to unfold itself from a capsule once inside your stomach and…to remove a coin cell! The robot can easily crawl into the stomach thanks to a magnet responding to external magnetic fields. Using the same magnet it can carry the coin cell out of the body. In theory. The robot has indeed only been tested within a molded, model, pig stomach.

    There are 3.500 swallowed button batteries cases each year in the US. We have no information regarding how many of these victims are electrochemistry/materials science PhD students eager to get rid of embarrassing results. But at least their supervisors have now a chance to get the coin cell battery back.

  • The 2016 edition of the Electrospinning for energy conference (ELEN) will be held in Montpellier (France) from June 22th to June 24th, 2016. The conference will tackle the application of nanofibers produced from electrospinning for energy conversion and storage devices. The conference is organized by RS2E researchers (Christel Laberty-Robert, Frederic Favier, Lorenzo Stievano), among others.

    The programme and registration are available here:

  • Saft and Total, two members of RS2E since 2011, signed an agreement this week just before Total filed an offer to buy Saft for €950.000.000! Saft, a renowned lithium-ion battery manufacturer for specialty applications (satellites, boats etc.), is a logical target for Total which has been monitoring the battery field closely for some time (with investments in Donald Sadoway’s - from MIT - battery company Ambri among others).

    "The acquisition of Saft is part of Total’s ambition to accelerate its development in the fields of renewable energy and electricity” says Patrick Pouyanné, CEO of Total.

    This deal will allow Saft to develop a greater engineering capacity, more funding, a powerful worldwide network and hopefully get head-to-head with battery giants such as LG Chem or Tesla. It will also place Total in the position to test and develop new and upcoming battery technology quickly using Saft’s up and running R&D facility (read our interview of Saft’s head of R&D, Anne de Guibert here)
