En­han­cing the me­cha­ni­cal sta­bi­li­ty of in­ter­faces in solid-​state Li-​ion bat­te­ries for energy-​intensive ap­p­li­ca­ti­ons - SO­LI­MEC

Pro­ject sum­ma­ry

The cli­ma­te con­fe­rence in Glas­gow 2021 em­pha­si­zed the im­por­tance of re­du­cing CO2 emis­si­ons. This en­dea­vor re­qui­res a more si­gni­fi­cant step to­wards sus­tain­able en­er­gy sources and sto­rage. The ra­tio­na­le for this pro­ject is to im­pro­ve the next ge­nera­ti­on of emer­ging solid-​state Li bat­te­ries (SSLBs), which can eli­mi­na­te ha­zards and en­er­gy den­si­ty is­su­es as­so­cia­ted with con­ven­tio­nal li­quid electrolyte-​based Li-​ion bat­te­ries (LIBs). To achie­ve this goal, five lea­ding re­se­arch groups and a large tech­no­lo­gi­cal com­pa­ny in the EU have de­ve­lo­ped the fol­lo­wing stra­te­gy to face the cur­rent chal­len­ges of SSLBs. We rely on mul­ti­com­po­nent en­gi­nee­ring of ca­tho­de ma­te­ri­al and its in­ter­face with the solid-​state elec­tro­ly­te to pre­vent stress-​induced loss of con­tact du­ring char­ge/dischar­ge, which de­gra­des elec­tron/ion trans­fer, and thus im­pro­ving the SSLB per­for­mance and lon­ge­vi­ty. Po­ten­ti­al be­ne­fits are seen in the ap­p­li­ca­ti­on of SSLB as true al­ter­na­ti­ve to LIB to re­place fos­sil fuels in the car in­dus­try.
