A group of researchers at the Gwangju Institute of Science and Technology (GIST) in Gwangju, South Korea, said they have developed a “universal method” to extend the life of lithium-ion batteries.
A release describing the breakthrough states that “the advent of electric vehicles has created a demand for high energy density lithium-ion batteries. This has led to the development of anodes with high charge capacity. Unfortunately, this memory capacity tends to decrease over several charge/discharge cycles, reducing battery life.
He says the shortened battery life is due to “an irreversible volume change in the anode during cycling, which causes the electrical contacts to deteriorate and the structure to collapse.”
The sequence of events for the charge/discharge cycle is as follows:
The GIST researchers discussed their findings in detail in a paper published earlier this year in the Journal of Materials Chemistry A.
Professor Hyeong-Jin Kim, a co-author, said the goal was to develop an electrode process that could increase energy density in line with the rapid growth of the battery industry.
“The method developed by the researchers strengthens the anode and makes it more resistant to volume changes by encapsulating the nanoparticles in an elastic network-like structure.”
They then used a technique called spin coating to cover the surface of the anode with a material called reduced graphene oxide (rGO): “The RGO coating acted as a seed layer to deposit a protective layer of zinc oxide with magnesium and gallium metal oxides (MGZO) attached to it. This layer of MGZO gave the anode a structural stability,” the publication said.
“In testing, the modified anode was able to retain most of its charge even after multiple charge/discharge cycles.”
Kim claimed that the design retained a large amount of memory after 500 cycles and showed a 91 percent coulombic efficiency related to battery life. “This could pave the way for electric vehicles that allow us to travel long distances on a single charge,” he said.
Notably, the researchers said that “anodes can be modified regardless of how they are made, making it a universally applicable method to improve battery life.”
