10 Ionizing Papers (May 2018)

This is our roundup of interesting articles on Li-ion batteries published in May – 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. Buying a car but don’t know whether to go for petrol, diesel, or electric? It seems many car dealerships have a strong (and often misleading) preference for internal combustion engines. This study across Scandinavia shows how much of a barrier they pose to the adoption of EVs. Nature Energy
  2. A nail-penetration test is one of the most common safety tests for batteries. Yet, conclusions are often made based on smoke, fire, or explosion. What about peeking directly inside the cell, instead, to see the crucial structural changes in real time? Journal of Power Sources
  3. Watch out, because artificial intelligence and automation are about to aid in the discovery of new energy materials! Nature Reviews Materials
  4. By 2020, China only is expected to generate 2.5 billion of spent Li-ion batteries with a mass of around 500 000 tons. This brief open-access review on recycling technologies is thus very timely reading. Engineering
  5. Solid electrolyte will be among the key ingredients in solid-state lithium metal batteries. To get it right, researchers often blend ceramics with polymers or liquids, or mix different ceramics together. Learn more, from theory to practical implications. Journal of Power Sources
  6. ‘One battery does not fit all’ – a good case for hybridization of battery pack chemistries. Here, an academic-industrial collaboration examines the benefits of combining Li-metal polymer cells with LTO cells (Journal of Energy Storage) and NCA cells with LTO cells (Applied Energy) in one EV battery system.
  7. A separator is not usually perceived as an ‘active’ cell element. But maybe it should be, considering it could prevent detrimental cross-contamination between the electrodes. ACS Applied Energy Materials
  8. Drones are here and in large numbers. And if you wonder, this is an example of how the design, implementation, and validation of UAV Battery Management Systems (BMS) is done. Reliability Engineering & System Safety
  9. Understanding ageing in Li-ion batteries is critical. Dig deep into the chemistry of it! Chemical Society Reviews
  10. Heat is a persistent issue in battery modules and packs, especially with such craving for high power. And it’s up to Thermal Management Systems (TMS) to remove and/or distribute it to prevent cell degradation. See the latest developments – from air and liquid cooling to novel phase-change materials. International Journal of Energy Research
