  • Publication number: 20240170720
    Abstract: An electrochemical cell that cycles lithium ions includes a first electrolyte, a second electrode, a separating layer disposed between the first layer and the second layer. The first electrolyte includes a nickel-rich positive electroactive material that includes greater than or equal to about 80 mass % of nickel (Ni). The second electrode includes a silicon-based negative electroactive material. The electrochemical cell also includes an electrolyte in contact with at least one of the nickel-rich positive electroactive material in the first electrode and the silicon-based negative electroactive material in the second electrode. The electrolyte includes greater than or equal to about 1.5 wt. % to less than or equal to about 5 wt. % of an electrolyte additive. The electrolyte includes one or more isocyanate functional groups.
