This paper focuses on the prediction of temperature profiles on the surface of lithium-ion cells using a non-parametric method. In particular, this paper proposes the adoption of the impulse response technique to compute and interpret cell surface temperat ...
The integration of inorg. nanocrystals as building units into mesoscale architectures yields materials whose structure is controllable on at., nano, and meso length scales providing a foundation for understanding how system-level functional properties emer ...
As a promising cathode inheritor for lithium-ion batteries, the sulfur cathode exhibits very high theoretical volumetric capacity and energy density. In its practical applications, one has to solve the insulating properties of sulfur and the shuttle effect ...
Background: LiCoO2 is one of the most used cathode materials in Li-ion batteries. Its conventional synthesis requires high temperature (>800 degrees C) and long heating time (>24 h) to obtain the micronscale rhombohedral layered high-temperature phase of L ...
Within the context of the electrical circuit modeling of batteries, this paper proposes an improvement of the most common electric equivalent circuit used for Lithium cells. The main improvement is based on the modeling of the so-called charge redistributi ...
