Orion Crest, Series_1

Chapter 174: Two papers

　　"Yes." Startled by Orion's aura, Connie placed the sample of positive electrode material in a glassware for safekeeping and quickly returned to the battery mould, using a pipette to extract a small amount of electrolyte from it and collecting it in a test tube for sealing.

　　On the other hand, Orion walked quickly to the corner of the lab and held out the lab's Fourier Transform Infrared Spectrometer.

　　Infrared spectroscopy is generated by the absorption of infrared light of a specific wavelength when the molecules of a compound vibrate, and the wavelength of the infrared light absorbed by the vibration of the chemical bond depends on the kinetic constants of the chemical bond and the reduced mass of the atoms connected at the two ends, so each compound has its own unique infrared spectra, which is why infrared spectroscopy is also known as "molecular fingerprinting".

　　Based on the absorption peaks in the infrared spectrum, Orion used a computer to quickly characterise the composition of the electrolyte, measuring the mass fractions of all the sulphur-containing functional groups and related compounds in the electrolyte.

　　The results were promising.

　　Polysulfur compounds were indeed present in the solution, but at rather low levels. Even as an industrial application, this material is acceptable despite its flaws.

　　It was not only the results of the analysis of the electrolyte that surprised Orion, but also the observations under the scanning electron microscope were equally pleasing.

　　At the nm scale, the porous structure of sample 23 was able to allow the electrolyte to enter the interior of the composite, increasing the ionic conductivity. At the same time, the adsorption capacity on its surface, in turn, effectively prevents the diffusion of polysulfide compounds into the electrolyte, thus effectively curbing the shuttle effect.

　　And this confirms Orion's claim that hollow carbon spheres are a promising direction.

　　Of course, that's not the most critical thing.

　　The key point is that hollow carbon nanospheres with a specific surface area of up to 3025m2g-1 and a diameter of 69nm meet Orion's previous prediction!

　　That is, hollow carbon nanospheres with a specific surface area in the range of [2326m2g-1, 3762m2g-1] and a diameter in the range of [60nm-70nm] are able to effectively inhibit the diffusion of polysulfide compounds in the electrolyte!

　　"Unbelievable ...... we did it, we did it!" Connie waved his fists excitedly, and if he wasn't worried that speaking out loud would interfere with the instrument, he couldn't even resist shouting out loud.

　　The corner of Orion's mouth also raised a smile, and the stone hanging in his heart also fell to the ground.

　　Although there was still a long way to go before the shuttle effect was completely solved.

　　But without a doubt, this was a good start.

　　"Don't be too excited, we haven't completely solved the shuttle effect," Orion continued after a moment's pause, "after a maximum of 500 times, the rate of loss of anode sulphur material will rise, and at the same time, the rate of specific capacity decay will begin to amplify, this technology still needs to be improved. "

　　Connie said, "Man, you're being too hard on yourself. If everyone demanded that research results must be taken by industry and made into products, we wouldn't need to continue our experiments!"

　　This was something Connie wasn't lying about.

　　As far as this result was concerned, it was absolutely outstanding.
