Rechargeable batteries using bis- or tris-fused tetrathiafulvalenes as an active electrode material exhibit good cycle performance by controlling the number of electrons participating in the redox reaction. The TTPY cell using a four-electron redox process shows a discharge capacity of 168 mAh g−1 and good cycle-life stability of 84 % of the initial capacity after 100 cycles (see charge-discharge curves).
