Abstract
The invention relates to a lithium-ion cell (1) for an energy storage unit of a motor vehicle, having at least one anode (3), at least one cathode (4), an electrolyte and a separator (7) arranged between the cathode (4) and anode (3) in the electrolyte, and having a reference electrode (8) for determining a voltage potential of the lithium-ion cell (1). The reference electrode (8) is produced from lithium titanate.
Claims3
A lithium-ion cell (1) for an energy storage unit in a motor vehicle, comprising at least one anode (3), at least one cathode (4), an electrolyte and a separator (7) arranged between the cathode (4) and anode (3) in the electrolyte, and having a reference electrode (8) for determining a voltage potential of the lithium-ion cell (1), characterized in that the reference electrode (8) comprising lithium titanate powder is pressed directly onto the separator (7).
A method for producing a lithium-ion cell (1) for an energy storage unit of a motor vehicle, comprising:
- an anode (3), a cathode (4), an electrolyte and a separator (7) arranged between the anode (3) and the cathode (4), and further comprising a reference electrode (8), wherein the reference electrode (8) comprises lithium titanate powder, wherein the reference electrode (8) is pressed directly onto the separator (7).
