Charge the green future: Recent advances in lithium-ion batteries could make them ubiquitous: Scientists add a specific polymer composite to the silicon anode of lithium-ion batteries, which significantly increases battery life
Lithium ion batteries (LIB) operate electric vehicles and electronics. With the prevalence of these increasing, efforts have been directed towards improving the efficiency and longevity of LIBs. Now researchers at the Japan Institute of Science and Technology have shown that adding a specific polymer composite bond to the silicon anode of LIBs can significantly improve its structural stability, making it feasible for much more powerful, long-lasting LIBs, and changing the future of. the technologies it drives.
Think of a battery, and the term lithium-ion most likely comes to mind. Due to its light weight, high-energy density, and ability to deliver three times more power than other types of rechargeable batteries, lithium-ion batteries (LIB) have become the dominant type of battery in both low-power consumer electronics, such as mobile phones, and high-power ones. applications, such as electric vehicles and energy storage.
Every typical lithium-ion battery today consists of a positive electrode (cathode) made up of a lithium-containing compound, a negative electrode (anode) made of graphite, and an electrolyte – the layer between the electrodes through which ions flow. When a battery is charged, lithium ions flow from the cathode to the anode, where they are stored. During the discharge process, the lithium is ionized and moves back to the cathode.
Recently, there has been a growing interest in using silicon as the anode material because it is more abundant, and therefore cheaper, and has a higher theoretical discharge capacity than graphite. However, it has a key drawback: repeated loading and unloading causes the silicon particles to expand and burst. This results in the formation of a thick solid-electrolyte interface (SEI) between the electrolyte and the anode, which prevents the movement of lithium ions between the electrodes.
To improve the performance of silicon anodes in LIBs, a team led by Professor Noriyoshi Matsumi, as well as including Dr. Agman Gupta and Lecturer Rajashekar Badam, of Japan’s Advanced Institute of Science and Technology (JAIST), has developed a link for silicon. items that can improve their stability and maintain a thin SEI layer. Now, unlike a thick SEI layer, thin is useful because it prevents the anode and electrolyte from spontaneously reacting with each other. The results of the study are published in ACS Applied Energy Materials.
The bond is a polymer compound consisting of an n-type conducting polymer (bisiminoacenaphthenequinone) (P-BIAN) and a carboxylate-containing polymer (acrylacid) (PAA), each bonded to the other by hydrogen bonds. The composite polymer structure holds the silicon particles together like a net and prevents them from bursting. The hydrogen bonds between the two polymers allow the structure to self-repair, as the polymers can bind together if they separate at some point. In addition, the n-doping capacity of P-BIAN improves the conductivity of the anode and maintains a thin SEI by limiting the electrolytic decomposition of the electrolyte on the anode.
To test the bond, the researchers constructed an anodic half-cell consisting of silicon nanoparticles with graphite (Si / C), the bond (P-BIAN / PAA) and an acetylene black (AB) conductive additive. The Si / C / (P-BIAN / PAA) / AB anode was placed through a repeated charge-discharge cycle. The P-BIAN / PAA link has been observed to stabilize the silicon anode and maintain a specific discharge capacity of 2100 mAh g-1 for more than 600 cycles. In contrast, the capacity of the bare silicon-carbon anode dropped to 600 mAh g-1 within 90 cycles.
After the test, the researchers disassembled the anode and examined the material for any cracks that may have resulted from a silicon rupture. Spectroscopic and microscopic examination after 400 cycles revealed a smooth structure with only a few microcracks indicating that the addition of the link could improve the structural integrity of the electrode and maintain a uniform SEI.
The results show that the addition of the link can improve the characteristics of the silicon anode and make it practically feasible. “The design and application of new polymer composites consisting of n-type conducting polymers (CPs) and proton donating polymers with hydrogen bonded networks, such as P-BIAN / PAA, holds a promising future in high-capacity electrode materials,” says Prof. Matsumi. .
As the demand for lithium-ion batteries increases, silicon, which is the eighth most abundant material on earth, will be a promising environment-friendly alternative to graphite. The improvements to its structural stability and its conductivity with the use of binders will make it more suitable for use in future lithium-ion batteries. “This principle of link compound design will enable a wider spread of EVs, creating other vehicles powered batteries and drones that require higher energy density for advanced performance,” says Prof. Matsumi.
