The hydrogel is polymerized in situ , resulting in a well-connected 3D network structure of Si nanoparticles (SiNP) coated by the conducting polymer. A g -1 , the composite electrode exhibited a relatively stable reversible lithium capacity of 1,600 mAh g -1 for 1,000 deep cycles based on the weight of only Si. Click to enlarge.

These electrode assemblies are then sandwiched together with conventional separators and positive electrodes to make the battery, which is filled with an acid electrolyte, sealed and connected in series to the other cells. Sustain 80-85% round trip efficiency in PSOC applications; 90-95% in deep cycle applications. PbC battery.
