High Energy Density Lithium Ion Battery Offers Cheap, Eco-Friendly Alternative

From:CTECHI GROUP Limited     Release time:2018-09-19

Overview:Batteries Recently, some American researchers has discovered this energy storing device after they realized that the new battery operates in a totally different manner than their prediction. The team carried out lots of experiments and was surprised to discover that the device was experiencing a totally different process. Instead of just moving around the zinc ions, the team's zinc-manganese oxide battery was going through a reversible chemical reaction that transformed its active materials into completely new ones.

Chemical inclination

Researchers have been woking for a very long time on rechargeable high energy density lithium ion battery, and this has led to exploring the back-and-forth movement of lithium ions. A process known as intercalation is used by the high energy density lithium ion battery to store and discharge energy. In this process, lithium ions enter and leave microscopic spaces existing between the atoms of anode and cathode of a battery.

This concept has already been widely built in energy storage research. When Ameican scientists worked together with the University of Washington, they started to consider a low-cost, safe alternative to thin lithium ion rechargeable battery. The scientists considered a rechargeable zinc-manganese oxide battery, because they believed that zinc will be capable of similarly entering and exiting the battery's anode and cathode.

Attractive alternative

Wang and his team started to examine rechargeable zinc-manganese batteries because they are found to be attractive on paper. These batteries can be very inexpensive, like the lead-acid batteries, because they use cheap and abundant materials like manganese and zinc. The battery can also have higher energy density than lead-acid batteries. The the USA scientists assumed that by investigating more on the inner performance of the zinc-manganese oxide battery, they would be able to develop a battery with enhanced performance.

Based on this assumption, the scientists went ahead and created a battery with a manganese dioxide anode, a zinc cathode, and a water-based electrolyte in between the two. The team placed tiny, button-sized test batteries through the wringer, and then repeatly charge them. Their test battery rapidly lost it's ability to store energy after just a few charging cycles.
