The German Federal Ministry of Education and Research (BMBF) kwa nthawi yoyamba ndalama zachitukuko chachikulu kuti apange mabatire okonda zachilengedwe komanso otsika mtengo omwe ayenera m'malo mwa mabatire otchuka a lithiamu-ion. Pazifukwa izi, Undunawu udapereka ma euro 1,15 miliyoni kwazaka zitatu ku mabungwe angapo asayansi ku Germany, motsogozedwa ndi Karlsruhe Institute of Technology. Kukula kwa zida ndi matekinoloje opangira mabatire a sodium-ion ikuchitika mkati mwa dongosolo la polojekiti yamtundu wa TRANSITION, yomwe idapangidwa kuti ipange ku Germany malo atsopano okonda zachilengedwe komanso abwino kuti agwiritse ntchito ndikusunga mphamvu zochulukirapo kuchokera kuzinthu zongowonjezwdwa.
Mabatire a lithiamu-ion anali mulungu wamagetsi kumapeto kwa zaka za zana la makumi awiri. Yopepuka, yopepuka, yamphamvu. Chifukwa cha iwo, zida zamagetsi zam'manja zidafalikira, ndipo magalimoto amagetsi adawonekera m'misewu yapadziko lonse lapansi. Panthawi imodzimodziyo, lithiamu ndi zinthu zina zapadziko lapansi zomwe zimagwiritsidwa ntchito popanga mabatire a lithiamu-ion ndizosowa komanso zowopsa pazinthu zina. Kuphatikiza apo, nkhokwe za mabatire a lithiamu-ionzi zimawopseza kuti ziume mwachangu. Mabatire a sodium-ion alibe zovuta zambiri za mabatire a lithiamu-ion, kuphatikiza kutulutsa kopanda malire kwa sodium ndi kuyanjana kwake ndi chilengedwe (mkati mwa chifukwa).
Kupambana pakupanga mabatire a sodium-ion amphamvu achitika posachedwa. Kuchokera ku 2015 mpaka 2017, zopeka zosangalatsa zidapangidwa zomwe zimatipatsa chiyembekezo chakupita patsogolo mwachangu popanga mabatire otsika mtengo a sodium-ion okhala ndi mikhalidwe yoyipa kuposa anzawo a lithiamu-ion. Monga gawo la pulojekiti ya TRANSITION, mwachitsanzo, akukonzekera kugwiritsa ntchito carbon yolimba yomwe imachokera ku biomass monga anode, ndipo multilayer oxide ya imodzi mwazitsulo imatengedwa ngati cathode.
