10 Ionizing Papers (December 2018)

This is our roundup of interesting articles on Li-ion batteries published in December – 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. “Exceptional performance reported for battery materials and devices in the scientific literature is often measured under conditions that are not aligned with practical applications.” – the opening line of a paper that aims to bridge the performance gap between academic and industrial research. Required reading for every battery scientist and engineer! Nature Communications
  2. And one more for your reading list – a guideline on how to calculate specific energies and energy densities for different battery chemistries (from active materials to a cylindrical cell). So it feels more like comparing apples to apples. Advanced Energy Materials
  3. Many efforts are underway to scale up solid-state batteries. One of the first production challenges is making and then coating an electrolyte slurry. What kind of binder, what ratio, what content of solids, and what deposition parameters? This is a case of sulfide electrolyte. Journal of The Electrochemical Society
  4. Electricity is coming to aviation. Here is a technological, economic, and environmental assessment of an all-electric aircraft (Nature Energy). And here are design considerations if you actually want to build one (Progress in Aerospace Sciences).
  5. Looking for truly low-cost battery pack testing? There is a solution – it’s run on Raspberry Pi using open-source Python software. Electronics
  6. It’s hard to determine the true economic value of battery storage in grid applications. Such value depends on the battery chemistry, the system control, the most frequent functions, not to mention the local market rules and prices. But a team of engineers and economists from California, the State of battery farms, is now offering an open-source evaluation tool. Nature Energy
  7. Physico-chemical models are important for understanding fundamental behavior of a cell and estimating its internal states. The problem is finding the right set of parameters to obtain realistic simulation results. May we present to you the complete physical, electrochemical (JES), and thermal (JES) parametrization of a commercial high-power cell.
  8. Data, data, data. If you have a battery production line, use data mining to identify process dependencies and key quality drivers. Journal of Power Sources
  9. The separator has never been considered a very active (or attractive) component of a cell. Nonetheless, it increasingly appears to be. The more we understand the chemistry that passes through and surrounds the separator, the more active (and attractive) its role might become. Nature Energy
  10. Only a very small percentage of spent Li-ion batteries is reused or recycled. Where is the problem? Let’s have a closer look at the manufacturing supply chain. Sustainable Materials and Technologies
