Professor Chen Chia Chun, Chair Professor of the Department of Chemistry, National Taiwan Normal University and his team have developed a rechargeable aluminium ion battery and Nature Communications accepted the result.
Lithium batteries are batteries that have lithium as an anode. These types of batteries are also referred to as lithium-metal batteries and has been applied to cell phones, electronic appliances and electric cars. Aluminum is one of the most abundant metals on earth, and aluminum products are found everywhere in daily necessities (eg, aluminum foil, aluminum cans, etc.). Aluminum also carries the same characteristics as lithium batteries but the cost is quite low, so that’s why scientists have been hoping to use aluminum in battery.
They stand apart from other batteries in their high charge density (long life) and high cost per unit. Depending on the design and chemical compounds used, lithium cells can produce voltages from 1.5 V (comparable to a zinc–carbon or alkaline battery) to about 3.7 V.
Disposable lithium batteries are contrasted with lithium-ion and lithium-polymer, which are rechargeable batteries, where ions move between the anode and the cathode, using an intercalated lithium compound as the cathode material and without using lithium metal as the anode material.
Corresponding author professor Chen is a Chair Professor at NTNU. Graduated from National Tsing Hua University, Harvard University, he has taught in National Chung Cheng University.
First author Wang Di Yang received his bachelor, master and doctor degree in the Department of Chemistry in NTNU. He has worked in the Academic Sinica as research fellow and assistant professor in NTNU. Prof. Wang is the first scholar in NTNU whose article was accepted by Nature. It is needless to say that young scholars from NTNU have shown their soft power in the academic field. This semester, Prof. Wang started his teaching career at Tung Hai University.
