Despite their promise, these systems present significant challenges for investigation due to their inherent complexity and computational limitations [1]. In this talk, we will explore the application of analytically solvable statistical physics models to the study of nanostructured ionotronic systems. I will present insights from both lattice [2,3] and off-lattice [4] models, emphasizing their differences and relevance to phenomena such as ion ordering [5], quantum capacitance effects [6], and strategies for optimizing the performance of ionotronic-based devices [7,8,9]. I will particularly highlight results that are challenging to achieve with widely used molecular simulations, showcasing the unique utility and power of analytically solvable models.</div><div> </div><div><b><span class="Apple-tab-span" style="white-space:pre"> </span>Acknowledgements</b></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>This work was supported by the Polish National Science Centre (NCN) under grants Nos. 2021/40/Q/ST4/00160 and 2020/39/I/ST3/02199.</div><div> </div><div><b><span class="Apple-tab-span" style="white-space:pre"> </span>References</b> </div><div><span class="Apple-tab-span" style="white-space:pre"> </span>[1] Kondrat, Feng, Bresme, Urbach, and Kornyshev, Chem.
