Calendar and cycle life study of Li(NiMnCo)O2-based 18650 lithium-ion batteries
Madeleine Ecker,Nerea Nieto,Stefan Käbitz,Johannes Schmalstieg,Holger Blanke,Alexander Warnecke,Dirk Uwe Sauer +6 more
TL;DR: In this paper, an extensive set of accelerated aging tests has been carried out employing a Li-ion high energy 18650 system (2.05-Ah), negative electrode: carbon, positive electrode: Li(NiMnCo)O2).
Journal ArticleDOI
Parameterization of a Physico-Chemical Model of a Lithium-Ion Battery I. Determination of Parameters
Madeleine Ecker,Thi Kim Dung Tran,Philipp Dechent,Stefan Käbitz,Alexander Warnecke,Dirk Uwe Sauer +5 more
TL;DR: In this article, the parameters to fully parameterize a physico-chemical model for a 7.5 Ah cell produced by Kokam are determined and compared with existing literature values.
Journal ArticleDOI
Technical Viability of Battery Second Life: A Study From the Ageing Perspective
Egoitz Martinez-Laserna,Elixabet Sarasketa-Zabala,Igor Villarreal Sarria,Daniel-Ioan Stroe,Maciej Swierczynski,Alexander Warnecke,Jean-Marc Timmermans,Shovon Goutam,Noshin Omar,Pedro Rodriguez +9 more
TL;DR: Evaluated lithium-ion nickel manganese cobalt/carbon (NMC/C) battery state of health (SOH) and ageing history over the second life performance on two different applications, a residential demand management application and a power smoothing renewable integration application showed a strong influence of the first life battery ageing history upon the secondlife battery performance and degradation.
Journal ArticleDOI
Differential voltage analysis as a tool for analyzing inhomogeneous aging: A case study for LiFePO 4 |Graphite cylindrical cells
TL;DR: In this paper, differential voltage analysis (DVA) is evaluated for LiFePO 4 |Graphite cylindrical cells aged in calendaric and cyclic tests, and the results from this analysis exhibit an increasing homogeneity of the lithium-ion distribution during aging for all cells subjected to calendaric aging.
Proceedings ArticleDOI
