Safe battery life of lithium battery

As we all know, the battery life of mobile devices has entered a bottleneck period in recent years. Lithium battery manufacturers have to increase the battery capacity to solve this problem. However, increasing the capacity is not a long-term solution. But researchers determined to make a difference haven't given up, and have recently come up with a new solution: condensing, which improves battery life while keeping lithium-ion batteries safe and flexible enough to accommodate the possibility of flexible mobile devices.

So what is condensation? Actually very simple, is to use ice template (ice - templating) solid electrolyte in the vertical alignment cell structure, enhance the electrical conductivity. The new batteries also pave the way for the concept of flexible smartphones and tablets.

At the moment, the liquid electrolyte in rechargeable lithium batteries on the market is highly flammable and can cause safety problems, as was the case with the Note7 last year. So Columbia University's school of engineering and applied sciences decided to try using solid electrolytes instead of flammable liquid electrolytes.

Because traditional liquid electrolytes are highly flammable, they use ice templates to give the ceramic solid electrolyte a vertically aligned columnar structure. Batteries using ceramic solid electrolytes are significantly safer and more conductive. This is done by adding ceramic particles to the bottom of the battery and cooling the aqueous solution. The ice is then allowed to grow and a portion of the frozen aqueous solution is squeezed out, allowing the ceramic particles to become mainstream in the battery. Finally, a vacuum is created to sublimate the ice into a vapor state, which completes the vertical alignment. Once the vertically aligned structure is in place, it needs to be combined with a polymer, a large molecule made up of many repeating subunits, which provides the electrolyte with mechanical support and flexibility.
