Scientists from Singapore have created a unique battery of household waste. According to its characteristics, it is twice as good as those used in modern smartphones. This is reported by the publication Chemical Engineering.

Employees of Nanyang Technological University processed disposable paper packaging — bags and cardboard boxes — in a special way. They could be turned into electrodes for batteries.

Using a laser, the researchers cut the paper into thin sheets that had lattices of various shapes. Then they were heated to a temperature of 1200 degrees Celsius, using a special stove without flame for this. Paper could be turned into carbon, water vapor and oil.

The resulting carbon was converted into electrodes. They turned out to be durable, flexible and had very good electrochemical properties. Experts have found that the battery can withstand up to 1200 cycles of charging and discharging. This figure is twice the resource of modern smartphones.

Researchers from Singapore have patented their development and subsequently plan to bring it to market.
