According to foreign media reports, scientists from the nanobiology Laboratory (NBL), a * star, have developed a novel method to prepare the next generation lithium sulfur cathode, which simplifies the time-consuming and complex production process of lithium sulfur battery cathode. The research shows that the commercialization of lithium sulfur battery has a hope, and solves a challenge in the industry, that is, a practical method is needed to produce materials that can improve the performance of battery on a large scale. Although people generally think that lithium-ion battery is an advanced technology, which can effectively provide power for communication equipment, but because of its inherent electrochemical property is not stable, there are shortcomings such as limited storage capacity and lack of security. However, NBL research team developed a new simplification technology, which can develop lithium sulfur battery cathode from cheap commercial materials, thus changing the status quo. In theory, the high energy density, low cost and abundant reserves of sulfur contribute to the popularization of lithium sulfur battery system, and then replace lithium-ion battery. Theoretically, lithium sulfur batteries can store 10 times more energy than lithium-ion batteries, but so far, such batteries can not be recharged. However, the cathode developed by NBL shows a good specific capacity, up to 1220 MAH / g, which means that 1220 MAH charge can be stored per 1g cathode material. In contrast, the specific capacity of a typical lithium-ion battery cathode is 140 MAH / g. In addition, after more than 200 charging cycles, the capacity of NBL lithium sulfur battery cathode is still very high, and the loss of performance is minimized. The key to achieve this performance is that NBL adopts a unique two-step cathode preparation method. Before adding sulfur, the researchers first constructed a carbon scaffold to obtain a 3D interconnected porous nano material. Different from the traditional method of preparing cathode, this method can prevent the carbon bracket from collapsing when the battery is charged. At the initial stage of battery charging and discharging, the traditional cathode carbon bracket will collapse, which will lead to the change of the whole battery structure. Finally, the density of the traditional cathode becomes higher, the surface area is smaller and the pore is smaller, which leads to the performance of the battery is lower than that of NBL battery. In fact, the specific capacity of NBL cathode is 48% higher than that of traditional sulfur cathode, and the capacity fading rate is reduced by 26%. If more sulfur is added to the cathode, the practical surface area capacity of NBL cathode is up to 4 MAH / cm2. NBL researchers are not only designing and optimizing cathodes, but also designing and optimizing anodes, cell diaphragms and electrolytes using nanomaterials. The goal of the researchers is to develop a complete set of lithium sulfur battery system. Compared with the traditional lithium-ion battery, the system will have stronger energy storage capacity and longer life than the existing battery, which can bring great benefits to electronic equipment, electric vehicles and power grid energy storage.
