Area of Science:

• Computational chemistry
• Materials science
• Polymer science

Background:

• Solid polymer electrolytes are crucial for advanced battery technologies.
• Efficient computational methods are needed to understand polymer and ion dynamics.

Purpose of the Study:

• To introduce a novel computational method for simulating polymer growth.
• To improve the efficiency and accuracy of sampling polymer electrolyte structures.

Main Methods:

• The threading subunits for polymers (TSP) method involves equilibrating monomer conformations with solvation shells.
• Subsequent connection and minimization of subunits generate polymer structures.
• The method focuses on sampling near-equilibrium structures with well-dispersed ions.

Main Results:
