摘要
The rising of flexible and potable electronics urgently calls for matchable and miniaturized energy storage system as power supply. Herein, we develop a solution-processable method to fabricate Ni@Ni(OH)2 fiber to design an all-solid-state fiber-shaped Zn//Ni(OH)2 battery. This battery exhibits a high open circuit voltage of 1.75 V which is close to the theoretical value, considerable discharge capacity of 704 μAh cm−3 at current density of 0.5 A g−1, good rate capability with 75 % capacity retention when the discharge current increases from 0.5 A g−1 to 5 A g−1 and good cycling stability (92 % capacity retention after 2000 charge-discharge cycles). Furthermore, the device performance remains unchanged under bending conditions, showing good flexibility and stability. It is believed that our design provides a promising strategy to fabricate long fiber-shaped Zn//Ni(OH)2 battery as power supply for wearable electronics in future practical applications.
