Electrolyte calculation

The expression of solvent proportion a: B: C: D = 1:2:3:4 note: A / B / C / D is the abbreviation of solvent, 1,2,3,4 can use any legal number (excluding the percentage sign). Between the solvent name and proportion is an English equal sign. This part of text is placed at the front, followed by an English Teaser sign for separation
Special case: FB, FEC and other materials are sometimes used as additives and sometimes as solvents, so they are not included in conventional solvents. If FEC (or any other unconventional solvents), they need to be manually added at the end of FEC or FB_ S mark indicates that it can be treated as solvent
