Abstract (en)
[origin: WO2020216597A1] The invention relates to a method for forming a Li-ion battery cell comprising a cathode material, an anode material, a separator and an electrolyte, the electrolyte comprising a mixture of a polyethylene oxide and an oxide of formula LivLasZnOn, characterised in that it comprises the following successive cycling steps: (a) at least two successive charge and discharge cycles of the cell at a first cycling rate C/x, the charge/discharge steps being limited in time to x/2; (b) at least two successive charge and discharge cycles of the cell at a second charging rate C/y, different from the first cycling rate, where y is lower than x, the charge/discharge steps being limited in time to y/2; and (c) at least two successive charge and discharge cycles of the cell at a third cycling rate C/z different from the first and second charging rates, where z is lower than x and y, the charge/discharge steps being limited in time to z/2.
