Ndị ọkà mmụta sayensị German anaghị akwụsị ịtụ anya. Ụlọ ọrụ nkà na ụzụ nke Karlsruhe bipụtara akwụkwọ akụkọ na-ekwupụta ọmụmụ ihe na-atọ ụtọ. Ọ tụgharịrị na paramita nke batrị lithium-ion nwere ike imeziwanye nke ọma site na iji akwa akwa nkịtị.
N'ọnọdụ ọgbara ọhụrụ, akwa akwa na-agakarị n'iyi. A na-eji ya eme ihe na-esi ísì ụtọ na ọbụna n'ụlọ ọrụ eletrọnịkị maka imepụta ionistors (supercapacitors), mana n'ọtụtụ buru ibu, a na-atụba ya n'ime ụlọ. Ka ọ dị ugbu a, shei ahụ nwere ihe na-agba agba n'ụdị calcium carbonate (CaCO3) na ihe nkiri nwere protein dị n'ime, na ihe ndị nwere porous na-achọsi ike na mmepụta nke batrị lithium-ion.
Ụlọ ọrụ Helmholtz Ulm, n'okpuru nkwado nke Karlsruhe Institute of Technology na mmekorita ya na ndị ọrụ ibe si Australia, haziri ọmụmụ banyere ihe onwunwe nke eggshells dị ka ihe maka electrodes na batrị lithium-ion. E bipụtara nsonaazụ nyocha ahụ n'akwụkwọ akụkọ Dalton Transactions of the Royal Society of Chemistry.
Nnyocha ahụ chọpụtara na electrodes eggshell gbajiri agbaji dabara nke ọma maka imepụta batrị lithium-ion dị ọnụ ala site na iji electrolyte anhydrous. Batrị nnwale nwere electrode eggshell, ka 1000 chaja na mwepu cycles, tụfuru naanị 8% nke ikike mbụ ya. Nke a karịrị ezigbo njirimara maka batrị.
