Don't know that it's optimal, but it seemed to be a point where the degradation was significantly less in Dahn's slides. I'm trying to charge at about c/25 about 3 kw or 13 amps at 240 V. The goals of the Chair are to develop lithium ionīatteries with longer lifetime, higher energy density and lower cost.Īs Dahn says, "Our goal is to do something useful, not publish papers It is possible that the Chair willīe renewed in 2021. NSERC/Tesla Canada Industrial Research Chair that Jeff Dahn will holdįrom Jto June 7, 2021. NSERC, Dalhousie University and Tesla Motors have established the "Dahn Lab Begins 5-year Tesla Partnership Tesla probably uses good additives that also reduce the effect especially since Professor Dahn and his students consult directly with Tesla. High temperatures make it worse and Tesla has good battery pack thermal management.ģ. Tesla uses a battery chemistry with the least effect of parasitic side reactions.Ģ. Turns out it is bad to too slowly charge Lithium ion due to longer exposure to parasitic side reactions, BUT:ġ.
