Journal ArticleDOI
The thermodynamic origin of hysteresis in insertion batteries
TL;DR: This work presents, for the first time, a general explanation of the occurrence of inherent hysteretic behaviour in insertion storage systems containing multiple particles and predicts the existence of apparent equilibria in battery electrodes, the sequential particle-by-particle charging/discharging mechanism and the disappearance of two-phase behaviour at special experimental conditions.
Journal ArticleDOI
Impact of the Carbon Coating Thickness on the Electrochemical Performance of LiFePO4 / C Composites
Robert Dominko,Marjan Bele,Miran Gaberscek,Maja Remškar,Darko Hanzel,Stane Pejovnik,Janko Jamnik +6 more
TL;DR: In this article, it was shown that carbon coating thickness can be controlled by the amount of carbon and it has an impact on the obtained reversible capacity and the atomic ratio of nonactive Fe(III) phase in as-synthesized LiFePO 4 /C composites.
Journal ArticleDOI
Structure and electrochemical performance of Li2MnSiO4 and Li2FeSiO4 as potential Li-battery cathode materials
TL;DR: Nyten et al. as discussed by the authors reported preparation and preliminary testing of Li 2 FeSiO 4, a representative of a new class of Li storage materials, and revealed partial occupation of alternate tetrahedral sites by Li and Mn.
Journal ArticleDOI
Generalised equivalent circuits for mass and charge transport: chemical capacitance and its implications
Janko Jamnik,Joachim Maier +1 more
TL;DR: In this article, an exact equivalent circuit including terminal parts, which takes account of electrical and chemical control parameters in a unified way, is derived for a cell with a mixed conductor (or electrolyte) without internal sources or sinks.
