Recently, a team of Polymer Science and Engineering Department of Zhejiang University developed a new type of aluminum-graphene battery, which can be used for 5 hours if it is charged to a cell phone for 2 hours in the future. Related papers December 15 Posted in Science Advances.
According to Zhejiang University, the public number, said the new aluminum - graphene battery can be minus 40 degrees Celsius to 120 degrees Celsius environment can be described as both high temperature and anti-cold.
And in the minus 30 degrees Celsius environment, this new battery can achieve 1,000 charge and discharge performance diminished, and in the 100 degrees Celsius environment, it can achieve 4.5 million times the stability cycle.If the smart phone with this battery, every day Even if charging 10 times, can also be used for nearly 70 years.
The new battery is flexible and retains its full capacity after it is bent 10,000 times, and it does not catch fire or explode even when it is exposed to flames.
The R & D team said that 'the performance of a battery depends crucially on the state of electrons and ions running between the positive and negative electrodes.' 'The graphene battery cathode material uses the' Three Highs and Three Consecutives' principle of design to maximize the number of electrons and Ions flow freely, or quickly 'homing'.
'Three high' refers to the microstructure of high quality, high orientation, high porosity; 'three continuous' refers to the macrostructure has a continuous conductive network, continuous ion transport channels and continuous ion channeling.
