| titleOfInvention | Wide-temperature aluminum ion battery based on cobalt boride/graphene composite material as anode |
| abstract | The invention relates to a wide-temperature aluminum ion battery taking cobalt boride/graphene composite material as a positive electrode, and belongs to the field of batteries. The nano cobalt boride and the graphene are compounded and serve as the anode material of the aluminum ion battery, so that the battery has two energy storage mechanisms, namely an oxidation-reduction mechanism and an embedding and releasing mechanism, and the battery has good temperature characteristics due to the special structure (a crystal region and an amorphous coexisting) of the nano cobalt boride. By combining the above-mentioned composite material preparation method and battery test, the present invention can summarize the following characteristics: a novel composite material applicable to an aluminum ion battery system is obtained; the battery temperature performance test obtains an excellent result, namely in a high-temperature test, the battery capacity tends to rise along with the rise of the temperature, in a low-temperature performance test, the discharging specific capacity can reach 75mAh/g at the temperature of 20 ℃ and the current density of 500mA/g, the discharging specific capacity can still reach 45mAh/g at the temperature of minus 30 ℃ and the current density of 500mA/g, the capacity retention rate is up to 60%, and the battery has excellent low-temperature performance. |
