Abstract:
The formation of lithium dendrites is recognized as the worst problem for lithium metal batteries. Herein, a multifunctional additive is proposed for highly stable lithium metal in the carbonate electrolyte of Li-sulfurized polyacrylonitrile batteries with high areal capacity. This multifunctional electrolyte additive (fluoroethylene carbonate and potassium nitrate) forms a stable hybrid solid electrolyte interphase, and the K+ ions provide a self-healing electrostatic shield that can suppress lithium dendrites.

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...

Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
Direct addition products are...
