Journal ArticleDOI
Degradation of lithium ion batteries employing graphite negatives and nickel-cobalt-manganese oxide + spinel manganese oxide positives: Part 1, aging mechanisms and life estimation
John Wang,Justin Purewal,Ping Liu,Jocelyn Hicks-Garner,Souren Soukazian,Elena Sherman,Adam Sorenson,Luan Vu,Harshad Tataria,Mark W. Verbrugge +9 more
TL;DR: In this paper, the aging and degradation of graphite/composite metal oxide cells were examined, and non-destructive electrochemical methods were used to monitor the capacity loss, voltage drop, resistance increase, lithium loss and active material loss during the life testing.
Journal ArticleDOI
Degradation of lithium ion batteries employing graphite negatives and nickel–cobalt–manganese oxide + spinel manganese oxide positives: Part 2, chemical–mechanical degradation model
TL;DR: In this paper, the authors measured capacity losses for 1.5-Ah Li-ion batteries with a mixture of Li-Ni-Co-Mn oxide (NCM) + Li-mn oxide spinel (LMO) as positive electrode material and a graphite negative electrode.
Journal ArticleDOI
Measurements of Hydrogen Spillover in Platinum Doped Superactivated Carbon
TL;DR: In this article, hydrogen uptake was measured for platinum doped superactivated carbon at 296 K where hydrogen spillover was expected to occur, and showed significant scatter and were not well above instrument background.
Journal ArticleDOI
Hydrogen Sorption Behavior of the ScH2−LiBH4 System: Experimental Assesment of Chemical Destabilization Effects
TL;DR: In this paper, the authors measured the isothermal kinetic desorption behavior in a hydrogen storage system and calculated the reaction enthalpy, which indicated that this system should be of interest at moderate temperatures, but the large heats of formation of the reactant phases appeared to play a critical role in determining overall kinetics.
Journal ArticleDOI
Metal hydrides based high energy density thermal battery
Zhigang Zak Fang,Chengshang Zhou,Peng Fan,Kent S. Udell,Robert C. Bowman,John J. Vajo,Justin Purewal,Bidzina Kekelia +7 more
TL;DR: In this article, a thermal battery based on advanced metal hydrides was studied for heating and cooling of cabins in electric vehicles, which utilized a pair of thermodynamically matched metal hyddrides as energy storage media.
