Abstract

This disclosure relates to semi-solid electrodes which are pre-formed prior to inclusion in lithium ion batteries, lithium ion batteries which incorporate the semi-solid electrodes and methods of making the semi-solid electrodes. An electrochemical cell includes a semi-solid anode formed of anode active material injected with an electrolyte and a first electrolyte additive, the semi-solid anode having a first SEI layer; and a semi-solid cathode formed of a cathode active material injected with an additional electrolyte and a second electrolyte additive, the semi-solid cathode having a second SEI layer, wherein the first electrolyte additive and the second solid electrolyte additive are different.
