On December 13, according to Futurism, as more and more companies and governments took measures to reduce their reliance on fossil fuels, it became clear that the voyage mileage of electric vehicles must be further extended. We must expand the battery's cruising range and production to surpass fossil-fuel-powered vehicles. In response to this necessity, companies such as Tesla, Toshiba, Panasonic, and Samsung have made great strides in improving battery life and capacity, but none of them have completely overcome major obstacles.
Figure: If the new technology can help extend the mileage of electric vehicles by 2 times, electric vehicles are expected to become mainstream vehicles.
However, researchers from the University of Waterloo have published a new paper saying that the use of a negative electrode made of lithium metal can "significantly increase the storage capacity of the battery", thereby greatly improving the performance of electric vehicles. The paper, published in the journal Joule, details how scientists have added compounds of phosphorus and sulfur to electrolytes. The researchers said that this compound reacts with the lithium metal electrode in the battery and covers it spontaneously with a very thin protective layer. This protection allows the use of lithium metal electrodes in the battery, which increases the storage capacity without risk. This improvement may extend the range of electric vehicles by two times.
On a small scale, this breakthrough may increase battery capacity and improve battery system efficiency. However, if these technologies can be applied to electric vehicles, then this is not just a slight improvement in technology. Battery capacity and cruising range are the fatal weaknesses of the current energy revolution, although it makes electric vehicles the second largest power model after fossil-fuel vehicles. Therefore, this development can not only greatly promote the development of electric vehicle technology, but it may also ultimately have a decisive influence on the continuous efforts of the environment and climate change process. If electric vehicles become the main means of transportation on the road, then greenhouse gas emissions will be greatly reduced, thereby increasing our chances of survival on the earth. (small)
