To ensure reliable operation, a thorough understanding and influence analysis of the instantaneous and hysteresis performance for LIBs under the extreme environments or operating conditions, such as mechanical extrusion, vibration, high- and low- temperatures, supergravity and microgravity, and low atmospheric pressure, is essential, which enables accurate assessment of their ability to meet energy and power demands over their whole service life.

It is found that the degree of charge transfer is strongly dependent on the energy offset between polymer and dopant (F4TCNQ). Pg<sub>3</sub>2T-Se with a shallowest HOMO level shows completely integer charge transfers (ICT) state, even dopant dianions (double doping) is detected at a low dopant concentration, while both ICT state and charge transfer complex (CTC) state are observed in doped P2T-Se with a deepest HOMO level. A remarkably electrical conductivity of Pg<sub>3</sub>2T-Se up to 1135.9 S cm<sup>−1</sup> is obtained via single-solution doping, which is attributed to its high carrier concentration. The microstructure evolution of polymer packing upon doping further indicate that the dopants insert into the side chain will facilitate the generation of ICT states. Our results demonstrate that a large energy offset, together with dopant located in the side chains (away from the backbone), promotes high doping level, thereby achieving high conductivity. Moreover, high-conductivity polymer film is attractive for sensor due to a low power consumption and an enhanced sensitivity.
