According to a report from the University of Maryland campus news network on March 31, engineers of the school reconstructed the wood structure and used it as a negative electrode structure for lithium batteries to enhance the safety and performance of batteries. The research paper entitled "Large Capacity, Low Bending and Channel-Guided Lithium Batteries" has been published in the March 20 issue of the National Academy of Sciences Proceedings. Lithium batteries play an important role in modern manufacturing. No matter whether it is a charging treasure, a mobile phone, a laptop or an electric car, it uses it to supply electricity. However, this type of battery will rapidly expand when it is fully charged and will contract when it is depleted. Obvious structural changes will lead to more lithium metal on the surface of the battery, and in the long run, it will cause explosions and other security risks. Scientists at the University of Maryland proposed to abandon the traditional practice of storing lithium ions using metal blocks and instead use natural channels in wood to transport water and nutrients to contain lithium ions. In this way, wood will become the "home of metal ions." Due to the fixed structure, the wood will not collapse or be damaged no matter how the amount of ions changes. In order to ensure that high current densities do not cause lithium ions to clog outside the “home†gate while charging, scientists have increased access to the interior of the wood. This kind of transformation makes the number of ions at each entrance small, the local current density is very small, the battery will not produce heat and hot phenomenon, it will avoid the explosion. In addition, due to the greater internal structure of the wood, the same volume condition can accommodate more power than the metal block. Researchers said that the current use of natural materials such as wood to improve the structure of lithium batteries is only part of the study. It is the natural biological structure that brings inspiration for scientific research. People can think of using renewable materials to create new ways of storing energy.
