New Material May Help Cut Battery Costs for Electric Cars

07.07.2017 | University of Texas at Dallas | www.utdallas.edu

In the battle of the batteries, lithium-ion technology is the reigning champion, powering that cellphone in your pocket as well as an increasing number of electric vehicles on the road. 

But a novel manganese and sodium-ion-based material developed at The University of Texas at Dallas, in collaboration with Seoul National University, might become a contender, offering a potentially lower-cost, more ecofriendly option to fuel next-generation devices and electric cars.

New type of material for batteries

The research team's sodium-ion design, which retains the high energy density of a lithium-ion cathode, replaces most of the lithium atoms (green) with sodium (yellow). The layered structure of the new material also incorporates manganese (purple) and oxygen (red).

A battery consists of a positive electrode, or cathode; a negative electrode, or anode; and an electrolyte in between. In a standard lithium-ion battery, the cathode is made of lithium, cobalt, nickel and oxygen, while the anode is made of graphite, a type of carbon. When the battery charges, lithium ions move through the electrolyte to the anode and attach to the carbon. During discharge, the lithium ions move back to the cathode and provide electric energy to run devices.
