The stress sub-model captures stress developed during lithium ion intercalation and deintercalation. State estimation based on coupled SPM and mechanical stress model is particularly challenging because the coupled model is given by nonlinear partial differential equations (PDEs).
Therefore, the governing equations for the solid phase lithium ion concentration with intercalation-induced stress is described by (6)-(8). U+( ) and U ( ) in Eq. (9) are the equilibrium potentials of positive and negative electrode material as functions of solid phase surface concentrations.
During lithium intercalation, hydrogen in L-SiH is redox active, and LiH bonds are formed in the interlayer, without destruction of Si planes.
V. CONCLUSION This paper presents a nonlinear observer for mechanical stress estimation in lithium-ion batteries, along with solid phase lithium ion concentration - i.e. state-of-charge. A key feature is utilizing a single particle model coupled with Fig. 2: Evolution of state estimation for UDDS 2 charge-discharge cycle.
Pseudocapacitance is commonly associated with surface or near-surface reversible redox reactions. The kinetics of charge storage in T-Nb2O5 electrodes is now quantified and the mechanism of lithium intercalation pseudocapacitance should prove to be important in obtaining high-rate charge-storage devices.
Particle fracture due to stress generation is a critical mechanism causing capacity fade, and thus reducing battery life. The stress sub-model captures stress developed during lithium ion intercalation and deintercalation.
