A topochemical reaction induced the formation of Bi2S3 micro-straws from a Bi-MOF for an ultra-long Zn storage life

The Bi 2 S 3 micro-straws is created by a topochemical reaction using Bi-PYDC template and the formation mechanism is investigated. Zn || Bi 2 S 3 -TH cell delivers high specific capacities of 153.4 mAh g −1 at 1 A g −1 after more than 10000 cycles.
