Research Featured by the Electrochemical Society!

March 6, 2019

Rollover failure is a major concern for lithium-ion cell producers around the world. Cells that seem healthy can sometimes fail abruptly with little or no warning. The Dahn Lab is performing comprehensive studies to understand why rollover failures occur and how to predict their onset.

The editorial board of the Journal of the Electrochemical Society has featured our most recent findings as an Editors' Choice in the latest issue - click here to read the full open access article!

'Leading the Charge' Toward Cobalt-Free Lithium-ion Cells

February 6, 2019

Nickel-rich positive electrodes have become a staple for electric vehicle and grid storage lithium-ion cells, yet their continued reliance on cobalt poses significant environmental, financial, and humanitarian concerns.

In a recent publication, the Dahn Lab asks "Is Cobalt Needed in Ni-Rich Positive Electrode Materials for Lithium Ion Batteries?"

Dahn Lab Operates 'Under Pressure', Publishes in Joule!

January 4, 2019

Doctoral candidate Alex Louli and recent Ph.D. graduate Leah Ellis demonstrate a new method using operando pressure measurements to measure SEI growth and to rank silicon-containing lithium-ion cells.

Dahn Lab Begins 5-year Tesla Partnership

June 8, 2016
NSERC, Dalhousie University and Tesla Motors have established the NSERC/Tesla Canada Industrial Research Chair that Jeff Dahn will hold from June 8, 2016 to June 7, 2021. It is possible that the Chair will be renewed in 2021. The goals of the Chair are to develop lithium ion batteries with longer lifetime, higher energy density and lower cost. As Dahn says, "Our goal is to do something useful, not publish papers in Nature and similar journals".

Governor General's Innovation Award

Jeff Dahn was awarded one of the six inaugural Governor General's Innovation Awards!
On May 19, 2016, Jeff Dahn travelled to Ottawa and received a Governor General's Innovation Award from David Johnston, the Governor General of Canada. This award recognized Dahn's innovations in developing advanced diagnostic methods to rank lithium ion battery lifetime (high precision coulometry, battery microcalorimetry, automated storage, etc.) in short term experiments. 

Congratulations Jeff!



Tesla Motors visits Dalhousie

On June 16, 2015, Dalhousie University and Tesla Motors announced that the Dahn group will switch industrial partners from 3M Canada to Tesla in June of 2016. The arrangement with Tesla will be exclusive and the substantial 5-year funding package will allow the lab to operate at approximately the same scale as at present. The focus of the partnership will be to help create Li-ion cells with longer lifetime (in decades), lower cost and higher energy density destined for use in Tesla products.
