  DandeLiion (available at dandeliion.com) is a robust and extremely fast
solver for the Doyle Fuller Newman (DFN) model, the standard electrochemical
model for (dis)charge of a planar lithium-ion cell. DandeLiion conserves
lithium, uses a second order spatial discretisation method (enabling accurate
computations using relatively coarse discretisations) and is many times faster
than its competitors. The code can be used `in the cloud' and does not require
installation before use. The difference in compute time between DandeLiion and
its commercial counterparts is roughly a factor of 100 for the moderately-sized
test case of the discharge of a single cell. Its linear scaling property means
that the disparity in performance is even more pronounced for bigger systems,
making it particularly suitable for applications involving multiple coupled
cells. The model is characterised by a number of phenomenological parameters
and functions, which may either be provided by the user or chosen from
DandeLiion's library. This library contains data for the most commonly used
electrolyte (LiPF6) and a number of common active material chemistries
including graphite, lithium iron phosphate (LFP), nickel cobalt aluminium
(NCA), and a variant of nickel cobalt manganese (NMC).
