10 Ionizing Papers (September 2018)

This is our roundup of interesting articles on Li-ion batteries published in September – a mix of educational, groundbreaking, helpful, thought-provoking, and topical. If you follow battery research, these are 10 papers you should be aware of (in no particular order):

  1. Our fundamental understanding of lithium transport in electrode materials is changing again. And this time X-ray diffraction and microscopy experiments point at where it all happens: the solid–liquid interface. Nature Materials
  2. How green are electric vehicles? There are numerous Life Cycle Assessments (LCAs) and, unfortunately, numerous diverging conclusions. This meta-analysis takes the LCA literature apart and finds that about 70% of the variability comes from the electricity generation. Applied Sciences
  3. Coating defects during manufacturing of electrodes are inevitable. But not all have the same impact on battery performance. Wonder which ones to worry about? Applied Energy
  4. X-ray tomography has enabled us to look inside cells. Non-destructively, from macro to nano scale, even in operando mode, it keeps revolutionizing battery research. Nature Reviews Materials
  5. Drivetrains are getting modular as more and more vehicle types go through electrification. To configure different traction machines, inverters, battery packs, and converters, there is now a simulation tool that helps optimizing it all. IEEE Transactions on Transportation Electrification
  6. Swelling of liquid electrolyte batteries is a common and widely investigated issue. Well, it’s time to start looking into gas generation in solid state batteries too. ACS Energy Letters
  7. China has well over 1,000,000 EVs on the road and is becoming the most important EV market on the planet. See how it has evolved and where it is headed. Energy
  8. Lithium “dendrites” can take on many forms – tip-growing dendrites, root-growing whiskers, or surface-growing clusters. They are different from each other, grow at different current densities, and have different safety consequences. This paper tries to understand, identify, and mitigate the hazardous ones. Joule
  9. Battery degradation models are growing in numbers, but they are often focused on a single scale, form factor, or technology. If you need to go beyond such boundaries, this review is for you. Journal of Energy Storage
  10. Is Europe losing the battery race? Its research is strong, but it houses less than 1% of the global battery cell manufacturing capacity. Here are some policy suggestions for how to stay in the game. Science
