Undergrad Difficult Series Battery Problem

Click For Summary
Modern batteries utilize double-sided anodes and cathodes to enhance energy density, typically connecting cells in series by linking anodes to cathodes. The idea of stacking these components with separators in a single cell raises questions about feasibility and safety. Concerns exist that either the anode or cathode could fail under high electrical loads, leading to battery failure. Additionally, the layered construction of lithium batteries, which are often rolled into cylindrical shapes, presents its own safety challenges. Overall, while innovative designs are explored, established manufacturers prioritize safer and more practical solutions.

Modern batteries use double-sided anode and cathodes for greater energy density. Series wiring of batteries is typically accomplished by connecting the anode of one cell to the cathode of another. However, can series be accomplished by stacking double-sided anode and cathode alternatingly with separators in one cell.

While your design might work in theory, battery makers have likely investigated it and decided on other more manufacturable and safer designs.

I would think either the anode or cathode would be destroyed by the amount of electricity coursing through it and that might precipitate battery failure.

lithium batteries are manufactured in layers and then rolled into a cigar and even this design has safety issues.

Thread 'What is the pressure of trapped air inside this tube?'
As you can see from the picture, i have an uneven U-shaped tube, sealed at the short end. I fill the tube with water and i seal it. So the short side is filled with water and the long side ends up containg water and trapped air. Now the tube is sealed on both sides and i turn it in such a way that the traped air moves at the short side. Are my claims about pressure in senarios A & B correct? What is the pressure for all points in senario C? (My question is basically coming from watching...
