Briefly describe the revolutionary breakthrough of lithium battery power

　　Recently, Apple deliberately made a fuss about the frequency reduction of the old iPhone, but it also reflects the stagnation of lithium battery technology over the years. Although you can see reports of revolutionary breakthroughs in battery technology from time to time, I haven't heard of which one has been put into commercial use.

　　Now, researchers from Nanyang Technological University (NTU) in Singapore have brought a new battery technology, not to improve the battery structure and increase the battery density, but to target the old and used batteries, claiming to make lithium-ion batteries in 10 Recovering to 95% of capacity within hours is equivalent to "rejuvenating".

　　Specifically, this new technology is to add a third electrode between the existing two electrodes in each lithium-ion battery, thereby discharging the remaining lithium ions from one electrode to the other, removing "impurities" that affect battery performance. .

　　Due to the limitation of natural properties, the longer the lithium battery is used, the more obvious the loss of capacity will be. Generally, 15-20% of the capacity will be lost after 300-500 charge-discharge cycles, and it cannot be reversed.

　　But Professor NTURachid Yazami said that his invention can quickly rejuvenate old lithium batteries, and the capacity recovery operation can be repeated on the same battery every few years, which can extend the battery life and is also conducive to environmental protection.

　　This invention has been tested on smartphones, but it is of even greater significance to the change in the electric car industry, because the average person may change a mobile phone in two years, but the car will last for more than ten years.

　　It is reported that industry giants such as Apple, Samsung and Panasonic are all very interested in this invention.
