10 Ionizing Papers (January 2018)

This is our roundup of interesting articles on Li-ion batteries published in January – a mix of educational, groundbreaking, helpful, thought-provoking, and topical. If you follow battery research, these are 10 papers you should be aware of (not in order of importance):

  1. Did you know commercial cells are often capable of much faster charging than what is recommended by the manufacturer? Look at the method that finds the maximum suitable current and makes 18650 NCA cells charge ~5x faster without compromising their safety limits. Electrochimica Acta
  2. Adhesion strength of electrode is often tested using a simple sticky tape. But what if you need something more accurate and ‘realistic’, like testing strength of the coating–foil interface under a combination of tension and shear? RSC Advances
  3. Negative electrodes are heading towards a silicon future – see the latest research update on Si-based anodes for Li-ion batteries, from fundamentals to applications. Small
  4. Is it possible to quantify social costs and benefits of grid-scale electrical energy storage? Yes, and it is even possible to set policy guidelines for future regulators who want cost-effective transition to clean power. Applied Energy
  5. The world talks about Tesla Semi. And about Thor Trucks’ ET-One. And Daimler’s E-Fuso Vision One… Well, read this ‘one’ if you want to know what is required from a battery for heavy-duty long-haul transportation – capacities, costs, charging stations, and of course, how it compares to diesel. Energies
  6. Battery aging is often tricky. It induces volume changes of electrodes, which then lead to pressure and volume changes in a cell (and subsequently in a module). Here, an electrochemical–mechanical battery model ties the electrode chemistry and mechanics to understand such aging little better… Journal of Power Sources
  7. How do you study solid–electrolyte interfaces in batteries? A bunch of methods to choose from, all in a comprehensive review with almost 1000 references! Chemical Society Reviews
  8. Lithium sulfur is a promising next-generation battery technology thanks to its high specific energy. How would its Life Cycle Assessment (LCA) stack against the current NMC 111 Li-ion battery in a mid-size EV? Energies
  9. It’s time for electrochemistry to explore machine learning: starting with surrogate models for a physics-based Li-ion battery model. JES
  10. Electrochemical Impedance Spectroscopy is hard to interpret, especially when similar spectra in literature can be interpreted using vastly different equivalent circuit models. Hey, there are now some useful conversion formulas so you can compare various physical assumptions or even results across different studies! JES
