CGN (Carrageenan) Powder as Battery Electrode Binder, 100 g/bottle, CBEBCGN

CGN (Carrageenan) is a family of natural, sulfonated polysaccharides extracted from red seaweed and its abundant sulfate groups will react chemically with polysulfides, acting as a "molecular anchor in Li-S battery research. Carrageenan possesses a linear, highly functionalized chain that provides excellent mechanical properties for Silicon (Si) anodes. The sulfate and hydroxyl groups in carrageenan form strong hydrogen and covalent bonds with the silicon surface, which is beneficial to suppress the volume expansion in Si anode. CGN can be operated at high voltage since it helps create a very homogeneous dispersion of active materials and conductive carbon, which reduces charge-transfer resistance and improves the battery's ability to charge quickly (rate capability).
