10 Ionizing Papers (April 2018)

This is our roundup of interesting articles on Li-ion batteries published in April – 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. It’s all about electric vehicles. And that’s why the Nature Energy’s latest issue focused fully on EV batteries – with amazing reviews on performance and cost of Li-ion materials, cell production, battery safety, and of course, application markets and competition. These are must-reads! Nature Energy
  2. Do you remember Samsung’s autopsy of its multi-billion battery problem in the Galaxy S7? The manufacturing flaw was traced using computer tomography (CT). And CT is becoming an increasingly more valuable tool for this very task – seeing defects inside the cells. Energies
  3. Lithium metal anode might be the most promising platform for future high-energy-density batteries. Learn the state-of-the-art and the potential directions for research & development. Joule
  4. Large-scale electrochemical energy storage is great for balancing renewable power generation and integrating it into the grid. Investors and policy makers have noticed. But there is inherent system degradation which makes its economic valuation and management complicated. Well, there is now also a decision-making framework to help. Nature Energy
  5. How do batteries handle a mechanical impact? An imperative question for the automotive industry. Here is an answer for one of the most common cases: transverse indentation. Journal of Power Sources
  6. Cobalt is an expensive but necessary component of most high-performance commercial cathodes. Not surprisingly, its market price has spiralled out of control. There have been attempts to move away from the conventional layered oxide structure of cathodes (which largely depends on Co), and this latest breakthrough is another significant step forward. Nature
  7. Battery management system, BMS, is the brain that can make cells operate at their best or at their worst. It balances performance, reliability, and safety. Want to understand how it works and how it makes all the decisions? These two open-access reviews will walk you through the basics of BMS technology – Frontiers of Mechanical Engineering, and BMS hardware – Applied Sciences.
  8. Imagine a future in which large and dense cities will operate fleets of automated EV taxis. Just done for Manhattan, New York: simulating taxi movements, optimizing battery range and charging infrastructure, and estimating related costs and environmental impacts. All of this and more. Environmental Science & Technology
  9. Much attention goes into understanding solid electrolyte interphase (SEI) formed on graphite anodes due to electrolyte decomposition. Now, researchers have connected another piece of this chemical puzzle – the formation of LiF. Nature Catalysis
  10. China, Germany, Japan, and the USA are superpowers of automotive battery technology. Take a look through the slideshows of each country’s current and future R&D activities, including their research and funding strategies! (note: the presentations are in the supplementary material section) Journal of Power Sources
