New lithium battery developed

FUDAN University researchers have developed a new type of aqueous rechargeable lithium battery that is more efficient and safer than current lithium batteries.

The aqueous lithium battery lasts twice as long in laptops and cell phones compared to batteries on the market, researchers said.

The research has been published in the latest issue of Scientific Reports, a journal published by the Nature Publishing Group.

Wu Yuping, a chemistry professor at Fudan University involved in the project, said the safety and reliability of lithium ion batteries prevent them from being adopted for large-scale energy storage.

The new battery has an output voltage of about 4.0V, a big breakthrough compared with the theoretical voltage of 1.3V, Wu said, adding it costs about 50 percent less than lithium batteries already on the market.
