Lithium batteries can already solve the problem of safe battery life using "ice".702535 polymer battery

　　As we all know, mobile devices have entered a bottleneck period in battery life in recent years, and major lithium battery manufacturers have had to increase battery capacity to solve this problem. However, increasing capacity is not a long-term solution, and the explosion of Samsung Note7 undoubtedly poured cold water on the entire lithium battery industry. However, researchers who are determined to innovate and change have never given up. They have finally discovered a new solution recently, which is the condensation method. This method can improve the battery life while ensuring the safety of lithium batteries, and can be bent to fully adapt to the possibility of flexible mobile devices.

　　So what exactly is condensation? In fact, it is very simple to use ice templates to vertically align the solid-state electrolyte structure inside the battery, enhancing conductivity. The birth of this new type of battery also paved the way for the concept of flexible smartphones and tablets.

　　At present, the liquid electrolyte used in rechargeable lithium batteries on the market is highly flammable and can easily cause safety issues. It was the culprit of last year's Note 7 accident. Therefore, the School of Engineering and Applied Sciences at Columbia University has decided to try using solid electrolytes instead of flammable liquid electrolytes.

　　Due to the high flammability of traditional liquid electrolytes, they use ice templates to present a vertically aligned columnar structure of ceramic solid electrolytes. Batteries using ceramic solid electrolytes are significantly safer and more conductive. The production method of this type of battery is also very rare. When making it, ceramic particles are first added to the bottom and the aqueous solution is cooled. Then, the ice layer is allowed to grow and a portion of the frozen aqueous solution is squeezed out, making ceramic particles the mainstream in the battery. Finally, creating a vacuum environment to allow the ice to rise into the Huawei steam state completes the construction of a vertical alignment architecture. After completing the vertical alignment architecture, it is necessary to combine it with a polymer, which is a large molecule composed of many repeating subunits, in order to provide mechanical support and greater flexibility for the electrolyte.
