J. Phys. Energy 3 (2021) 031503 N Tapia-Ruiz et al Figure 31. (a) 23 Na ex situ NMR spectra of NaMnO2 at different states of charge. Resonances corresponding to α-NaMnO2 , β-NaMnO2, and interfacial stacking faults are highlighted in green, blue, and red, respectively. Reprinted with permission from [233].

The movement of the signal from the diamagnetic (low chemical shift) regime to the paramagnetic (high chemical shift) regime shows the transition from isolated Na ions to quasi-metallic clusters.

Concluding remarks Although widely applied as an analytical technique, solid-state NMR continues to be a highly active area of research in itself, which engenders continual developments in experimental hardware and methodology. These ongoing advances are helping to deepen and transform our understanding of battery material structures and mechanisms, so that their material properties can be optimised. For the study of Na-ion battery materials in particular, NMR has already provided considerable insight and will continue to do so as faster MAS rates become more widely available and advances in DNP methodology provide ever higher sensitivity and selectivity.

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com | RSS | AMP |
