Abstract
An electrochemical cell that cycles lithium ions is provided. The electrochemical cell includes a first electrode, a second electrode, and an electrolyte layer disposed between the first electrode and the second electrode. The first electrode includes a first plurality of solid-state electroactive material particles and a first polymeric gel electrolyte, where the first polymeric gel electrolyte includes a first additive. The second electrode includes a second plurality of solid-state electroactive material particles and a second polymeric gel electrolyte that is different from the first polymeric gel electrolyte, where the second polymeric gel electrolyte includes a second additive. The electrolyte layers include a third polymeric gel electrolyte that is different from both the first polymeric gel electrolyte and the second polymeric gel electrolyte.
