In today's world of rapid technological development, the innovation of battery technology has once again attracted global attention. Recently, a research team from Fudan University published a breakthrough in the international authoritative journal Nature: they successfully developed a new technology that can "precisely repair" aging lithium batteries and give old batteries a new life.

For a long time, whether it is the gradual inability to charge mobile phone batteries, the reduction in the range of electric vehicles, or the sharp decline in battery performance in cold environments, these problems have troubled the majority of users. What is more worrying is that with the popularization of electronic devices, the number of waste batteries is also increasing sharply, which has brought considerable pressure to the environment.

After in-depth research, the research team of Fudan University found that the aging process of batteries is similar to the decline of human health, and the core problem lies in the loss of active lithium ions. If these lost lithium ions can be accurately replenished, the life of the battery will be greatly extended. Based on this discovery, the team innovatively developed a lithium carrier molecule, which is like a "magic drug" that can directly replenish lithium ions for batteries by injection.

Lithium battery "precision treatment" technology is available, and used batteries are expected to be "reborn"

According to Gao Yue, a member of the research team of the Department of Polymer Science at Fudan University, this lithium carrier molecule can not only effectively repair commercial batteries, but also has a relatively low cost. More importantly, its application prospects are very broad, not only limited to extending the life of existing batteries, but also expected to help the development of new green batteries.

So, how was this magical lithium carrier molecule developed? The research team made full use of the combination of artificial intelligence technology and chemical knowledge, digitized the molecular structure and properties, and built a huge database. By introducing related knowledge in organic chemistry, materials engineering technology and other aspects, the team finally found this ideal lithium ion carrier molecule after countless experiments.

The experimental results show that the lithium iron phosphate battery using this new technology can still maintain a "healthy" level close to the initial state after 12,000 uses, while traditional batteries will experience capacity decay and scrap after 2,000 uses. This achievement has undoubtedly injected new vitality into the development of battery technology.

At present, this technology has passed the test of a variety of batteries and has carried out in-depth cooperation with top international battery companies. The scientific research team said that they are working actively and hope that this innovative technology can be applied to real life as soon as possible to bring substantial improvements to people's daily life and environmental protection.
