α‐MoO 3 nanobelts are successfully lithiated by a secondary reaction. The capacity retention rate of lithiated MoO 3 nanobelts is 92 % after 15 cycles, whereas the non‐lithiated nanobelts retain only 60 % (see figure). The conductivity is increased by close to two orders of magnitudes after lithiation suggesting that Li + ions have been introduced into the MoO 3 layers during lithiation.
