Stanford/Tsinghua University to develop a self-healing battery

Now the biggest problem with lithium-ion batteries is that when you charge them more and more, the power of the anode is getting worse. This is obviously a big hindrance to our mobile future, and a recent research team from Stanford University has developed a battery that can heal itself, meaning it will never fail. In recent years, researchers have been working hard to increase the energy density of lithium electrons under the condition of reducing weight. A recent exciting discovery comes from the addition of silicon to the electrodes, which makes the battery's ability to gather electricity much larger than the current capacity of the oxide in the battery. The physical expansion of silicon can reach 300%, and the electron can be reduced effectively after expansion, which allows the material to be split in a few short hours. The self-healing compound, developed by Wang of Stanford and Wu of Tsinghua University in Beijing, can fix itself in an instant. "We found that the addition of self-healing compounds to the silicon electrodes could prolong their lifespan by 10 times times and fix previous divisions within a few hours," said Professor Bao's team, who helped develop a resilient electronic robotic enclosure. "Self-healing is important for prolonging the life of animals and plants, and we want to integrate that into lithium-ion batteries and prolong its lifespan," he said. Professor Wang said in an article published. The current battery technology can only guarantee no decay within the 100-time charging cycle. And the research team hopes to carry a self-healing technology of the battery, can be in the future to ensure that the phone 500 times charge cycle does not decay, and electric car 3,000 times the charge cycle does not decay.
