10 Ionizing Papers (October 2018)

This is our roundup of interesting articles on Li-ion batteries published in October – 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. An MRS Bulletin special issue delves into solid-state electrolytes! Choose from reviews on the modeling of ceramic ionic conductors, polymer and composite electrolytes, lithium metal stabilization, or the architectural design of solid-state batteries. MRS Bulletin
  2. Are you keeping track of the EV market? Models, prices, driving ranges, and charging times? If not, this is an open-access opportunity to catch up. Energy Policy
  3. Battery thermal management system (BTMS) keeps cells near their optimal operating temperature. It relies either on thermally conductive components to dissipate the excess heat, or alternatively, thermally insulating components to keep the battery from the cold. To avoid complexity and cost, BTMS is often designed for either hot or cold environments. But heads up: there is now an interesting solution that can passively handle both extremes. Nature Energy
  4. Many chemicals are OK at the lab scale, but less so when handled in tons. That’s when their performance has to be weighed against processability, toxicity, and cost, and that’s why the battery industry wants to work with water-based chemistry. And at the center of it all are aqueous electrode binders. Plenty to choose from, so go green! Energy & Environmental Science
  5. The cylindrical 18650 cell format (popularized by Tesla) is being replaced by its bigger and higher-energy successor 21700. If you wonder how 18650, 20700, and 21700 formats compare in terms of performance, specific energy, module integration, or production price, this is an open-access study to check. Journal of The Electrochemical Society
  6. Lithium-rich layered oxides are a focal point of cathode research. They suffer from significant stability issues, and so this analysis looks at one of the key aspects: their structural behavior at elevated temperature, atom by atom. JACS
  7. Impact loading is one of the most common causes of battery failure. The effect of mechanical impact depends on the dynamic load and the battery state of charge (SoC). And the coupling of the two. Energy
  8. International standards, such as V2G standard ISO 15118, are often considered too technical, obscure, or insignificant, yet they can play a major role in the transition of national energy systems. It very much depends on how each country implements them. Journal of Cleaner Production
  9. High specific energy cells simply can’t do without low weight. And this means, especially for Li-metal batteries, cutting down on electrolyte volume. Time to start talking about ‘lean electrolyte’ and what that means. Journal of Power Sources
  10. Redox flow batteries might be a tough competitor for Li-ion in stationary energy storage applications. Here is a discussion on the practical aspects of high performance large-scale flow batteries because it’s good to know your competition. Chemical Society Reviews
