12V27A battery

　　Stanford and Tsinghua University jointly develop "self-healing" battery

　　The biggest problem with lithium-ion batteries now is that as you charge them more and more times, their negative electrode's power-gathering ability becomes worse and worse. This is obviously a big obstacle to our mobile future. Recently, a research team from Stanford University developed a 12V27A batterythat can heal itself, which means it can never run out.

　　In recent years, researchers have worked hard to increase the energy density of lithium electrons while reducing weight. A recent exciting discovery comes from adding silicon to the electrodes, which can make the power-gathering capacity of the 12V27A batterygreatly exceed the power-gathering capacity of oxides in current batteries. The physical expansion of silicon can reach 300%, and electrons can effectively shrink after expansion, which allows this material to complete splitting in just a few charges and discharges.

　　The self-healing compound, developed by Chao Wang from Stanford and Hui Wu from Tsinghua University in Beijing, can repair itself in an instant. We found that adding a self-healing compound to the silicon electrode can extend its life 10 times, repairing the previous split within a few hours, said Stanford Professor Bao Zhenan (transliteration), Professor Bao Zhenan's team has helped Developing resilient electronic robot shells.

　　Self-healing is of great significance to extending the lifespan of animals and plants. We hope to integrate this feature into lithium-ion batteries and extend their service life. Professor Wang once said this in a published article.

　　Current 12V27A batterytechnology can only guarantee no degradation within 100 charging cycles. The research team hopes that batteries equipped with self-healing technology can ensure that mobile phones will not decay for 500 charging cycles in the future, and electric cars will not decay for 3,000 charging cycles.
