In terms of working principle, solid lithium battery are no different from traditional lithium batteries. The main difference between the two is that the electrolyte of solid-state batteries is solid, which is equivalent to the place where lithium ions migrate to the solid electrolyte. With the continuous upgrading of positive electrode materials, solid electrolytes can be better adapted, which is conducive to improving the energy density of battery systems. In addition, the insulation of solid electrolytes allows them to well isolate the positive and negative electrodes of the battery, avoiding short circuits caused by contact between the positive and negative electrodes while acting as a diaphragm.
Solid electrolytes have a wide electrochemical window and can adapt to higher voltage cathode materials.
Solid electrolytes have good mechanical properties and can effectively inhibit the formation of lithium dendrites, thus being compatible with lithium metal anode materials with higher energy density.
Due to the non-fluidity of the electrolyte, the electrodes inside the battery cell can be connected in series to increase the single cell voltage, achieving the same effect as increasing the voltage by connecting multiple batteries in series, thereby reducing the use of structural parts and increasing energy density when forming a group.
