Key Points

  • We present a Si-based anode with superior-performance close to the limits of theoretical capacities with an advantage of factor ×10 over any hitherto produced, commercial electrode system.
  • Our electrodes sustain physical bending without surface reconstruction or crack formation, and heat shocks without loss of capacity and overall cycling performance.
  • The critical, novelty that enables the extraordinary performance increase and durability of our anodes is a class of semi-conducting porous organic polymers that replaces all conventional additives in battery ink formulations.
