Advanced Battery Development: Researchers Find Strategy to Accelerate Charging Time for Lithium-Ion Batteries
In recent years, engineers and material scholars have been striving to create more advanced batteries that are charged faster, serve longer and can store more energy. These batteries play a key role in the development of electronics and energy, nourishing a wide range of portable devices and electric vehicles.
Today, the most common in the world are lithium-ion batteries (LIBS), which are used in most of our daily electronic devices. One of the main priorities in the field of energy is to find ways to speed up their charging without the need to switch to completely new batteries.
Researchers from the Huzhung University in China presented a new development strategy for rapidly recovered LIBS containing graphite material. Their battery design made it possible to accelerate the battery charging time, while maintaining most of their capacity even after thousands of charging cycles.
“The processes of desolvatation LI+ in electrolytes and diffusion at the border, the hard substance-electrolyte are the key stages that limit the rapid charge of graphite lithium-ion batteries,” write in their article Shuibin TU, Bao Zhan and their colleagues.
The research group conducted a series of thorough experiments, the purpose of which was to find out how the various components of the solid electrolyte interface (Solid Electrolyte Interface (SEI) affect the process of dissolving lithium ions (Li+). Ultimately, they determined a combination of materials that can improve the effectiveness of the process of desolvatation LI+, ensuring the rapid migration of Li+ ions via SEI.
The team identified a promising anode based on a material called P-S graphite, which consists of an ultra-thin layer of phosphorus on the surface of the graphite. These anodes were made and integrated into LIB
