abstract = {Investigations on the effect of flame retardant additives
(FRs) on the abuse tolerance of large scale lithium ion
battery (LIB) cells (5 Ah) are of high relevance in
battery science and industry but rarely performed as they
are cost and time consuming. In addition, even though FRs
are frequently investigated, their positive effect on the
safety properties of larger full LIB cells under abusive
condition has not been proven yet. The promising FR
(phenoxy) pentafluorocyclotriphosphazene (FPPN) is known to
exhibit excellent flame retardant‐ and electrochemical
properties at the same time. Therefore, FPPN is investigated
towards abuse tolerance in 5 Ah LIB cells in this study.
Calorimetric investigations show that a mass percentage of
$5 wt \%$ FPPN mixed to a standard electrolyte,
significantly reduces the self‐heating rate of 5 Ah
cells in the temperature range from 80 °C to 110 °C.
While nail penetration and external short circuit
experiments provide no significant difference between
standard and FPPN‐containing cells, an increased
overcharge tolerance and a favorable thermal stability at
≈120 °C in overcharge and oven experiments could be
shown.},
