The research team innovatively proposed the concept of zinc-iodine lithium 3400mah 3.7v 18650 battery

 

The reporter learned from the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences that the research team led by Li Xianfeng and Zhang Huamin, researchers from the Institute's Energy Storage Technology Research Department, innovatively proposed the concept of zinc-iodine lithium 3400mah 3.7v 18650 battery, achieving a utilization rate of nearly 100% for the electrolyte in the zinc-iodine single-flow, thereby greatly improving the energy density of the battery. The research results were published online in Energy and Environmental Science.

 

Large-scale energy storage technology is a key technology for realizing large-scale utilization of renewable energy. Liquid flow batteries have the characteristics of high safety, long cycle life, and high efficiency. They are one of the preferred technologies for large-scale energy storage. Zinc-iodine liquid flow battery is a type of liquid flow battery technology. Due to its high energy density and environmental friendliness, it has received increasing attention in recent years.

 

In previous studies, the research team improved the cycle life and power density of zinc-iodine liquid flow batteries by optimizing the electrolyte composition and membrane materials of zinc-iodine liquid flow batteries. However, the relatively low electrolyte utilization rate caused by internal blockage of zinc-iodine liquid flow batteries remains to be solved.

 

Unlike traditional zinc-iodine flow batteries, zinc-iodine single-flow batteries only have a flow circulation system on the negative electrode side, and the positive electrode electrolyte solution is directly fixed in the positive electrode cavity. Since the positive electrode of the zinc-iodine lithium 3400mah 3.7v 18650 battery is solid and has no flow circulation system, there is no problem of blockage of the solution pipeline and pump, so the iodine ions can be charged to solid iodine element, which increases the utilization rate of the electrolyte from about 50% to nearly 100%, and the energy density of the battery from the previous highest 80Wh/L to 205Wh/L.

 

In addition, the researchers used porous carbon felt as an electrode to ensure the high power density (0.1W/cm2) of the zinc-iodine lithium 3400mah 3.7v 18650 battery. The experimental results show that the zinc-iodine lithium 3400mah 3.7v 18650 battery can operate stably for more than 500 cycles at a current density of 80mA/cm2, and the performance has not been significantly attenuated. These studies provide important references for the development of new systems of high-energy-density flow batteries. .
