Yangi kaltsiy ion batareyasi
Recently, Tang Yongbing, a researcher at the Functional Thin Film Materials Research Center of the Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, and his team, together with Tsinghua-Berkeley Shenzhen Institute and Cheng Huiming, a researcher at the Shenyang National Research Center for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, developed a high-performance calcium ion Battery. By innovating the battery structure, they made the calcium ion battery have a new electrochemical reaction mechanism, and realized the stable charge-discharge reaction at room temperature. The relevant research results were published online in "Nature-Chemistry".
Ishqoriy tuproqli metall elementlar orasida kaltsiy past polarizatsiya, litiynikiga yaqin standart elektrod potentsiali, ortiqcha 2 valentlik ioni (zaryadlar soni litiy ionidan ikki baravar ko'p), mo'l zaxiralar va arzon narxlardagi afzalliklarga ega. Shu sababli, kaltsiy{1}}ionli batareyalar samarali va arzon-energiya saqlash batareyalariga aylanish imkoniyatiga ega.
2016 yilda tadqiqotchilar yangi turdagi kaltsiy ionli suyuqlik batareyasini ishlab chiqdilar.

Tadqiqotchilar kaltsiy ionlari bilan teskari qotishma reaktsiyasini o'tkazish uchun manfiy elektrod sifatida qalay folga ishlatadigan va faol material va oqim kollektorining integratsiyalashgan dizaynini qabul qiladigan yangi turdagi kaltsiy ion batareyasini taklif qilishdi; va anionlarning teskari interkalatsiyasini/deinterkalatsiyasini amalga oshirish uchun musbat elektrod sifatida grafitdan foydalanadi. Reaktsiya; elektrolit sifatida kaltsiy geksaftorofosfatida erigan va 5V yuqori kuchlanishga qarshilikka ega bo'lgan karbonat{0}}asosidagi erituvchini oling. Kaltsiy ion batareyasi mukammal elektrokimyoviy ko'rsatkichlarga ega
