Impact of Current Ripple on Li-ion Battery Ageing

Multi-method Integrated on Soc Estimation of Li-ion Battery

The Li-ion battery is studied base on its equivalent circuit model. The discrete state space equation is established using Ah counting method and OCV method. The filtering algorithm is set up under the noisy environments according to the principle of extended Kalman filter and simulated. The simulation results showed that the integrated of three algorithms could very well remove the environment...

Modelling Li Ion Battery Electrode Properties

In recent years, interest in using lithium-ion (Li-ion) batteries as power sources for a wide range of devices (particularly portable devices) has grown significantly. There is thus a real need to understand at a fundamental level a wide range of battery performance criteria (energy density, power density, safety, durability, cost). Our working group considered how to model the fundamental elec...

Microstructural Analysis of the Effects of Thermal Runaway on Li-Ion and Na-Ion Battery Electrodes

Thermal runaway is a phenomenon that occurs due to self-sustaining reactions within batteries at elevated temperatures resulting in catastrophic failure. Here, the thermal runaway process is studied for a Li-ion and Na-ion pouch cells of similar energy density (10.5 Wh, 12 Wh, respectively) using accelerating rate calorimetry (ARC). Both cells were constructed with a z-fold configuration, with ...
