Hysteresis Modeling in Li-Ion Batteries
IEEE Transactions on Magnetics, 2014This paper investigates the applicability of the scalar Preisach model to describe the hysteresis in the state of charge versus open-circuit voltage plane of lithium-iron-phosphate batteries. The model is implemented using the Everett function, identified with experimental data related to first-order reversal hysteresis branches.

The Li-Ion Rechargeable Battery: A Perspective
Journal of the American Chemical Society, 2013Each cell of a battery stores electrical energy as chemical energy in two electrodes, a reductant (anode) and an oxidant (cathode), separated by an electrolyte that transfers the ionic component of the chemical reaction inside the cell and forces the electronic component outside the battery.

Capacity estimation for Li-ion batteries
Proceedings of the 2011 American Control Conference, 2011This paper presents onboard capacity estimation algorithms for Li-ion batteries deployed in plug-in hybrid electric vehicles (PHEV) and electric vehicles (EV). Capacity estimation algorithms are developed based on an equivalent circuit model. The onboard estimation of battery capacity is treated separately for the driving mode and plug-in charge mode ...

In‐situ imaging of Li‐ion migration at interfaces in an all solid Li‐ion battery
Surface and Interface Analysis, 2020We investigated the migration of Li ions at an interface between a Li x Ti 5 O 12 (LTO) and a solid electrolyte in an all‐solid Li‐ion battery. The optical reflection of

Mg2+ Ion-exchange with the Li+ Ion in a Fast Li Ion-conducting Perovskite La0.55Li0.35TiO3
Chemistry Letters, 2002Abstract Mg2+ ion-exchange with the Li+ ion in a fast Li ion-conducting perovskite La0.55Li0.35TiO3 was successful using MgCl2–KCl molten salt. The lattice parameter decreased as a result of the ion-exchange. These results suggest that the driving force of the ion-exchange reaction depends primarily on a decrease in the lattice energy ...

Ceramic Li Ion Electrolytes for Next Generation Solid-State Li Ion Batteries
ECS Meeting Abstracts, 2014At present, there is a growing interest in the development of safe and low-cost all-solid-state Li ion batteries for transport applications due to their higher practical volumetric and gravimetric energy densities compared to other known secondary batteries.

Experimental simulation of internal short circuit in Li-ion and Li-ion-polymer cells
Journal of Power Sources, 2011A multi-parameter controlled pinch test was developed to study the occurrence of internal short circuits in Li-ion and Li-ion-polymer cells. By tuning the control parameters (i.e., cell voltage as well as pinching area, load, and speed), the pinch test can reproducibly create an internal short between a cell jelly-roll's inner layer electrodes as small

Recent Advancements in Li-Ion Conductors for All-Solid-State Li-Ion Batteries
ACS Energy Letters, 2017Inorganic solid lithium ion conductors are potential candidates as replacement for conventional organic electrolytes for safety concerns. However, achieving a Li-ion conductivity comparable to that in existing liquid electrolytes (>1 mS cm–1) remains a challenge in solid-state electrolytes.

Internal Hybrid Li-Ion Battery and Li-Ion Capacitor Energy Storage Cells
ECS Meeting Abstracts, 2017Lithium (Li)-ion battery (LIB) and electric double-layer capacitor (EDLC) are two widely used electrochemical energy storage devices. LIB is made with Li intercalated graphite anode and Li metal oxide cathode and EDLC is made with high surface activated carbon for both anode and cathode.
