  "description": "<p>Thin-film Solid-State Batteries (TFSSB) is one of most promising and quickly developing fields in modern electrochemical energy storage. Modeling these devices is<br>\ninteresting from theoretical and practical point of view. This paper represents a simulation approach for TFSSB which overcome a major drawback of available<br>\nmathematical models, i.e. decline in accuracy of the models at high current rates. A one-dimensional electrochemical model, including charge transfer kinetics on the<br>\nelectrolyte-electrode interface, diffusion and migration in electrolyte as well as diffusion in intercalation electrode has been developed and the simulation results are<br>\ncompared to experimental voltage-capacity measurements. A new definition of diffusion coefficient as a function of concentration, based on the experimental<br>\nmeasurements, is used to improve the performance of the model. The simulation results fit the available experimental data at low and high discharge currents up to 5<br>\nmA cm&minus;2. The models show that the cathode diffusion constant is a prime factor limiting the rate capability for TFSSB in particular for ultrafast charging applications.</p>",
