A recent study by the Karlsruhe Institute of Technology (KIT<\/a>) has shown that the formation of the solid electrolyte interphase, which is crucial for the functioning of lithium-ion batteries, occurs through the aggregation of solutions rather than directly at the electrode.<\/p>\n

The findings offer insights into developing more efficient and long-lasting batteries in the future.<\/p>\n

The researchers reached this conclusion through simulations, and the results of their study have been published in the Advanced Energy Materials<\/em> journal.<\/p>\n

These batteries, including liquid electrolyte batteries, function reliably on a solid electrolyte interphase (SEI) that forms when voltage is applied for the first time.<\/p>\n

The passivation layer, also known as the solid electrolyte interphase (SEI), plays a crucial role in a lithium-ion battery\u2019s electrochemical capacity and lifetime, as it is subjected to high stress during every charging cycle.<\/p>\n

When the SEI is broken down, the electrolyte is further decomposed, resulting in reduced battery capacity, ultimately determining the battery\u2019s lifetime.<\/p>\n

Controlling the properties of a battery requires a thorough understanding of the SEI\u2019s growth and composition. However, hitherto no approach has been able to decipher SEI\u2019s complex growth processes at broad scales and dimensions.<\/p>\n

It has remained a mystery how the particles in the electrolytes form a passivation layer up to 100 nanometers thick on the surface of the electrode, as the decomposition reaction is only possible within a few nanometers distance from the surface.<\/p>\n

The new study from KIT has successfully characterized the formation of the solid electrolyte interphase (SEI) using a multi-scale approach, solving a major mystery regarding the functioning of liquid electrolyte batteries.<\/p>\n

To understand the formation and properties of the passivation layer in liquid electrolyte batteries, KIT\u2019s Institute of Nanotechnology conducted over 50,000 simulations with various reaction conditions.<\/p>\n

The team discovered that the SEI follows a solution-mediated pathway, where SEI precursors formed directly at the surface join far away from the electrode surface via nucleation.<\/p>\n

This process forms a porous layer that eventually covers the electrode surface.<\/p>\n

Researchers can develop suitable electrolytes and additives to control SEI properties and optimize battery performance and lifespan by identifying key reaction parameters that determine SEI thickness.<\/p>\n

Recently, researchers at the Shandong Academy of Medical Sciences, China, and Kyushu Institute of Technology, Japan, upcycled<\/a> crab shells into porous, carbon-filled materials with various uses, including crab carbon, to create anode materials for sodium-ion batteries.<\/p>\n

Earlier this month, researchers at South Korea\u2019s Ulsan National Institute of Science and Technology developed<\/a> a perovskite solar cell using alkylammonium chloride to control the formation of defects in the perovskite layer.<\/p>\n
