SODIUM-ION BATTERY INDUSTRY


The working principle of a sodium-ion battery is similar to that of the lithium-ion battery following an intercalation-based “rocking chair” mechanism, whereby the embedding (intercalation) and stripping (deintercalation) process of sodium-ion between positive (cathode) and negative (anode) electrodes, which are parted by the separator soaked in electrolyte, realises charge and discharge.





In terms of product performance, sodium-ion batteries advantages include good safety, rate performance, and low temperature performance, but have the disadvantages of poor cycle life and its energy density is comparable to only that of conventional lithium iron phosphate batteries.


Due to the comparable energy density, excellent rate performance and significant cost advantage of sodium-ion batteries, they are considered cost-effective and will be applied to large-scale energy storage systems, two-wheeler electric vehicles and low-speed electric vehicles and are expected to complement and eventually replace lithium-ion batteries in the future. Large-scale energy storage systems mainly include wind power plants, solar power plants and household energy storage systems while low-speed electric vehicles mainly include logistics vehicles, agricultural vehicles, electric vehicles, electric buses and electric boats.

Today's KNOWLEDGE Share:PLA BOTTLE

-
Image
Today's KNOWLEDGE Share Ever wondered how we can reduce plastic pollution in India? The Mysuru-based Defence Food Research Laboratory (DFRL), affiliated with the DRDO, has launched an eco-friendly remedy with the introduction of biodegradable water bottles. Crafted from sustainable Polylactic acid (PLA) material, these bottles not only combat plastic waste but also contribute to reducing the overall carbon footprint. The best thing about this bottle is its all-encompassing sustainability approach – the bottle, cap, and label are all compostable. This innovation, derived from 100% bio-based and renewable sources, sets us on a path towards environmental conservation and fosters a greener and more sustainable future.

Today's KNOWLEDGE Share:High and low shear rate changes in Rheology

-

Today's KNOWLEDGE Share If a relatively high Mw grade flows from thin to thick, as shown in the picture, and if the time needed to fill the thick section is way shorter than the average polymer relaxation time, the polymer will not be able to reach its higher viscosity (corresponding to higher thickness/lower shear-rate). I am assuming here the polymer reached equilibrium low viscosity in the thin section, say for instance because it is much longer. Any pressure prediction not accounting for transient rheology would then overpredict the pressure to fill.Of course the diverging flow will further complicate the situation and mess with the molecular orientation created in the thin section, but to what extent ? Since this is more of a reasonable "conjecture", don't take this for granted, and discuss or share your opinion in the comments. There are hundreds of Rheology papers on the "4:1 contraction flow". Not sure I have ever seen any on the..."1:4 expansio

Today's KNOWLEDGE Share : biobased content of polycarbonate diols

Today's KNOWLEDGE Share MCG increases biomass content of polycarbonate diols Mitsubishi Chemical Group (MCG) has introduced grades of its Benebiol biomass-based polycarbonate diols that have a higher biomass content. The product is primarily used in the manufacture of polyurethane resins for coatings in sectors such as automotive, furniture and outdoor products. It is also used in the production of artificial leather. Existing Benebiol grades had a bio-based content of 20-50%, but the new HSS and NLDS grades have a biomass content in excess of 80%. Some of its previous petroleum-derived grades have also been converted to biomass, as the NLS grades. This, the company said, allows it to offer bio-based grades of all its Benebiol products. The shift to biomass-based raw materials while maintaining high-quality functions will contribute to our customers’ efforts to achieve sustainable manufacturing. source:MCG/www.utech-polyurethane.com
