"Nanoporous Substrate materials for Rechargeable Li-Air Batteries" by Hua Cheng, PhD, Newcastle University
The rechargeable Li-air battery has a key role to play for the storage of renewable energy and in future electric vehicles.
But it suffers from cycling fading and low rate capability; cathode materials (including substrate) were identifies as one of main responsible sources.
Here we compare several potential cathode substrates with widely used carbon materials based on results from cycling studies and FTIR measurement. Ag and TiC show promising properties.

"Mechanisms of catastrophic Battery Failure" by Nicholas Willard, University of Maryland
Battery failure can be generalized into two broad categories, slow progressive degradation and immediate catastrophic failure.
To date, most theoretical work has been performed on the former with little work focusing on how to model, predict, or mitigate the onset of catastrophic failure.
This presentation will explain the root cause mechanisms that lead to catastrophic failure and will offer solutions on how to better predict and handle this problem
