Analyze a more environmentally friendly new concept battery

A new, more environmentally friendly concept battery The positive and negative electrodes of the new concept battery are made of aluminum and anthraquinone-based organic materials, respectively. Organic cathode data can effectively store positive charge carriers (cations) in aluminum and chlorine-based electrolytes, and ions move back and forth between the positive electrode and the negative electrode to form an electric current.

Aluminum battery technology has the advantages of high theoretical energy density, manufacturing correlation, and good recovery effect. Compared with existing lithium batteries, the new aluminum battery concept can also significantly reduce processing costs. Patrik Johansson, professor of physics at the Chambers Institute of Technology, said: The material and environmental costs of this new battery are much lower than at the time, and it can be used on a large scale, such as building a solar park or storing wind energy. In addition, the energy density of this new type of aluminum battery is twice that of the current state-of-the-art battery. In the past, aluminum batteries used aluminum as the anode (negative electrode) and graphite as the cathode (positive electrode). But the energy content of graphite is too low to make high-performance batteries. However, in a new concept developed by Patrik Johansson and his partner at Chalmers Institute of Technology, Robert Dominko of the National Institute of Chemistry of Slovenia (Slovenian National Institute of Chemistry), An organic nanostructured cathode in which carbon-based molecular anthraquinone replaces graphite as the cathode. The anthraquinone cathode was further developed by JanBitenc, a visiting scholar at the National Institute of Chemistry of Slovenia (formerly known as the Chambers Institute of Technology). The organic molecules guessed by the cathode are better than the positive charge carriers (cations) in the storage electrolyte, adding to the energy density of the battery. Niklas Lindahl, a researcher at the Chalmes Institute of Technology who studies the mechanism of battery energy storage, said the new cathode data will allow the battery to choose a more suitable carrier to better utilize the potential of aluminum. Now we are continuing to find a better electrolyte to remove the chlorine in the current solution. So far, aluminum batteries have not been commercialized, and it is even a relatively new topic in the research field. What is worrying is whether aluminum batteries will eventually replace lithium batteries. We hope that aluminum batteries can replace lithium batteries. But more importantly, they can complement each other to ensure that lithium batteries are only used when necessary. So far, the energy density of aluminum batteries is only half that of lithium batteries, but the long-term goal is to achieve the same energy density. There is still room for improvement in the electrolyte and charging mechanism. In theory, aluminum is a better carrier than lithium because it is a multivalent metal, which means that each ion can compensate for more than one electron. In addition, aluminum batteries are expected to significantly reduce the harm to the environment. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
