N anoparticles of n‐type conjugated ladder polymer poly(benzobisimidazobenzophenanthroline) (BBL) and its analogue (SBBL) are prepared through a reprecipitation method. The ladder polymers are tested as anode materials for lithium‐ion batteries for the first time. They exhibit high capacity, good rate performance, and excellent cycle life, especially at high temperature of 50 °C.
