The work in brief

Birger's work develops thermodynamically consistent continuum models of reaction, transport, precipitation and mechanics in batteries, aimed at explaining degradation and guiding the design of electrodes and electrolytes. A large share concerns the solid-electrolyte interphase (SEI): its morphology and dual-layer structure, the transport mechanism behind its long-term growth (electron diffusion, neutral lithium interstitials versus solvent diffusion), its growth during cycling, and its chemo-mechanical interplay with silicon anodes and lithium metal, including voltage hysteresis, fracture and isolated lithium during stripping. Other recurring subjects are metal-air and zinc batteries (precipitation, zinc shape change, near-neutral and chloride electrolytes, MnO2 cathodes in zinc-ion cells) and continuum theories of highly concentrated electrolytes, ionic liquids, polymer and solid electrolytes, covering transference numbers, reference frames, space-charge layers and solvation in the double layer.

The earliest papers (2012–2014) model lithium–oxygen batteries, covering lithium hydroxide precipitation and rate-dependent Li2O2 morphology. From about 2015 to 2020 the focus moves to SEI growth theory and to zinc-air cells, with volume-averaged and multi-dimensional simulations validated against experiments. Since 2020 the work adds silicon and lithium-metal chemo-mechanics, zinc-ion batteries and degradation of satellite batteries using in-flight data. It also brings in Bayesian parameter estimation and model selection (EP-BOLFI, Bayesian quadrature) to parameterize SEI and aging models against measured data, alongside molecular dynamics and experimental electrolyte parameterization and, most recently, studies of battery simulation on quantum computers.
