  • One-dimensional structure pre-calciated materials as positive electrode for rechargeable calcium batteries and cell comprising the same
    Patent number: 11489157
    Abstract: The present invention relates to a calcium-based secondary cell containing: an electrolyte arranged between the negative electrode and the positive electrode and comprising a calcium salt of a fluorine-containing anion of formula (XFn)m? wherein n is a positive integer of at most 6 and m is a positive integer of at least 1 and m<n, a positive-electrode active material at the positive electrode which is a one-dimensional structure accommodating Ca2+ ions and has the formula (1): Can+2Me1(n+1)?y?zMe2yMe3zO3n+3??(1) wherein: Me1, Me2, Me3 are different transition metals; 1?n and n is not necessarily an integer; 0?y and y is not necessarily an integer; 0?z and z is not necessarily an integer.
