A cooperative behavior of Zn(2+) and Li(+) to conduct charges in a Zn-LiFePO4 battery is disclosed. When Li(+) dissolves into the electrolyte, Zn(2+) would deposit, and vice versa. In light of this cooperative behavior, the battery can be viewed as a super hybrid system, which combines the strong points of Zn-air battery, lithium-ion battery and redox-flow cell.

A multi-dimensional thermal and electrochemical coupled model is developed for Li-ion batteries.

Predicting lithium-ion battery (LIB) lifetime is one of the most important challenges holding back electrification vehicles, aviation, and grid. The continuous growth solid-electrolyte interface (SEI) widely accepted as dominant degradation mechanism for LIBs. SEI consumes cyclable lithium leads to capacity fade power via several pathways. However, also electrolyte solvent may lead dry-out, whi...

Accurate state of charge (SOC) estimation is of great significance for a lithium-ion battery to ensure its safe operation and to prevent it from over-charging or over-discharging. However, it is difficult to get an accurate value of SOC since it is an inner sate of a battery cell, which cannot be directly measured. This paper presents an Adaptive Cubature Kalman filter (ACKF)-based SOC estimati...
