The strong restraints of both the ener­gy tran­si­tion and the con­cern for sov­er­eign­ty guide much of the research car­ried out at UTC. With the rise of elec­tro­mo­bil­i­ty, bat­ter­ies are at the heart of many research top­ics, par­tic­u­lar­ly in UTC’s Rober­val and Avenues lab­o­ra­to­ries. Issues such as bat­tery age­ing, dura­bil­i­ty and per­for­mance and reuse are being devel­oped. UTC has pro­posed solu­tions for recharg­ing bat­ter­ies in a mat­ter of min­utes, for increased safe­ty, and for a bet­ter under­stand­ing of how bat­ter­ies work in rela­tion to their envi­ron­ment. This work ben­e­fits bat­tery inte­gra­tors (auto­mo­tive, aero­nau­tics, rail, net­works, etc.) and their man­u­fac­tur­ers. This is par­tic­u­lar­ly true for the devel­op­ment of sodi­um-ion bat­ter­ies, a tech­nol­o­gy that would elim­i­nate the need for crit­i­cal materials.
