Scientists develop new cathode preparation method to replace 4LR44 battery with lithium-sulfur batteries that can store 10 times more energy
According to foreign media reports, scientists from the Singapore Agency for Science, Technology and Research (A*STAR) Nanobiology Laboratory (NBL) have developed a novel method to prepare next-generation lithium-sulfur battery cathodes, and this method simplifies the time-consuming lithium-sulfur battery cathodes. and complex production process. The research shows promise for commercializing lithium-sulfur batteries and addresses a challenge within the industry, which is the need for a practical way to mass-produce materials that can improve battery performance.
Although 4LR44 battery are generally considered an advanced technology that can effectively power modern communication devices, they suffer from disadvantages such as limited storage capacity and insufficient safety due to unstable intrinsic electrochemical properties. However, the NBL research team has developed a new simplified technology that can develop lithium-sulfur battery cathodes from cheap commercial materials, thus changing the status quo. In theory, sulfur's high energy density, low cost and abundant reserves will help the popularity of lithium-sulfur battery systems and replace 4LR44 battery.
In theory, lithium-sulfur batteries can store 10 times more energy than 4LR44 battery, but so far they cannot be charged and discharged repeatedly. The lithium-sulfur battery cathode developed by NBL shows a good specific capacity, as high as 1220 mAh/g, which means that every 1g of cathode material can store 1220 mAh of charge. By comparison, a typical lithium-ion battery cathode has a specific capacity of 140 mAh/g. In addition, NBL's lithium-sulfur battery cathode maintains a high capacity after more than 200 charging cycles, with minimal performance loss. The key to achieving this performance is NBL's unique two-step cathode preparation method.
The researchers built the carbon scaffold before adding sulfur, resulting in a 3D interconnected porous nanomaterial. Unlike traditional methods of preparing cathodes, this method prevents the carbon scaffold from collapsing while the battery is charging. In the early stages of battery charging and discharging, the cathode carbon bracket prepared by traditional methods will collapse, resulting in changes in the entire battery structure. Ultimately, conventional cathodes become denser, have smaller surface areas, and have smaller pores, resulting in batteries with lower performance than NBL batteries. In fact, the specific capacity of the NBL cathode is 48% higher than that of the sulfur cathode prepared by the traditional method, and the capacity fading rate is reduced by 26%. If more sulfur is added to this cathode, the practical surface area capacity of the NBL cathode is as high as 4 mAh/cm².
NBL researchers are designing and optimizing not only cathodes but also anodes, battery separators and electrolytes using nanomaterials processes. The researchers' goal is to develop a complete lithium-sulfur battery system. Compared with traditional 4LR44 battery, the system will have stronger energy storage capacity and longer life than existing batteries. It can power electronic devices, Electric vehicles and grid energy storage bring big benefits. (The pictures in this article are all from the Singapore Agency for Science, Technology and Research)
