Researchers invent new hybrid electrolyte for high-performance Li-ion batteries

Lithium-ion batteries (LIBs) are one of the most widely used batteries in modern ICT society, including smartphones and electric vehicles. LIBs are repeatedly charged and discharged by lithium ions passing back and forth between the positive and negative electrodes, with the lithium ion electrolyte acting as a conduit for the ions.

Typically, organic electrolytes such as liquid ethylene carbonate (EC) and its gels have been used as lithium-ion electrolytes due to their voltage resistance and ionic conductivity. However, as liquids and gels are flammable, it is preferable to switch to safer polymeric solid electrolytes.

Solid polymeric electrolytes such as polyethylene glycol (PEG) have been proposed as shock resistant lithium ion electrolytes. However, PEG-based polymer electrolytes crystallize near room temperature, resulting in a significant drop in lithium-ion conductivity to around 10-6 S/cm at room temperature.

To solve this problem, a research group has invented a new type of polymeric solid electrolyte by combining a porous polymer membrane with pores of several microns and a photocrosslinkable polyethylene glycol PEG-based polymer electrolyte. The polymeric solid electrolyte achieved a wide potential window (4.7 V), a high lithium ion conductivity in the class of 10-4 S/cm, which is equivalent to a liquid and sufficient for practical use, and a high lithium ion transfer number. (0.39). The lithium ions that are transferred in the electrolyte move in various directions due to natural diffusion. The distance is several µm to 10 µm and does not always move linearly between the electrodes, which is one of the reasons for the decrease in ionic conductivity. In the present study, therefore, the performance of photocrosslinked PEG-based solid polymer electrolytes was improved by compounding them with micrometer-sized porous membranes.

This polymeric solid electrolyte not only shows high performance as an electrolyte, but is also expected to be effective in preventing the formation of Li dendrites (dendritic crystals), which can cause ignition, due to the inclusion of a porous membrane. Through the realization of safe and high-performance LIBs, this achievement will contribute to the realization of sustainable energy supply, which is the seventh goal of the SDGs.
