Deposition of Lithium metal on anodes contributes significantly to ageing of Li-ion cells.
Lithium deposition is connected not only to a drastic limitation of life-time, but also to fast …

Lithium-ion cells currently power almost all electronic devices and power tools; they are a
key enabling technology for electric vehicles and are increasingly considered to be the …

In this work, lithium plating is investigated by means of voltage relaxation and in situ neutron
diffraction in commercial lithium-ion batteries. We can directly correlate the voltage curve …

Temperature heavily affects the behavior of any energy storage chemistries. In particular,
lithium-ion batteries (LIBs) play a significant role in almost all storage application fields …

Battery degradation is a fundamental concern in battery research, with the biggest challenge
being to maintain performance and safety upon usage. From the microstructure of the …

The standard format for cylindrical Li-ion cells is about to change from 18650-type cells
(18mm diameter, 65mm height) to 21700-type cells (21mm diameter, 70mm height). We …

In this work the differential voltage analysis (DVA) is evaluated for LiFePO 4| Graphite
cylindrical cells aged in calendaric and cyclic tests. The homogeneity of the active lithium …

Non-uniform distribution of current density and temperature is inevitable especially in high C-
rate and it can lead to bad performance of battery. Therefore, the non-uniform effect (non …

A single-layered NMC/graphite pouch cell is investigated by means of differential local
potential measurements during various operation scenarios. 44 tabs in total allow for a …

Li-ion cells of the industrially-relevant formats PHEV1 (prismatic), multi-layer pouch, and
21700 (cylindrical) are directly compared by experiments for the first time. All three cell …
