Recently, Apple deliberately reduced the frequency of the old iPhone was a hubbub, but also from a side reflect the stagnation of lithium battery technology over the years. Although from time to time we can see some revolutionary breakthrough battery technology reports, but have not heard of Which one has been put into commercial use
Now researchers at Nanyang Technological University (NTU) in Singapore bring with them a new battery technology that aims not at improving the cell structure and cell density, but at using older, older batteries, known as Let lithium-ion battery in 10 hours, restored to 95% of the capacity, equal to 'rejuvenate'.
Specifically, the new technology adds a third electrode between two existing electrodes in each lithium-ion battery to discharge the remaining lithium ions from one electrode to the other electrode to remove 'impurities' that affect the performance of the battery. .
Because of the limitation of natural properties, the longer the lithium battery is used, the more the capacity sleep loss is more obvious. Generally, the capacity will be 15-20% after 300-500 charge-discharge cycles, and it can not be reversed.
but Professor NTU Rachid Yazami said his invention can make old lithium batteries quickly return to youth, and every few years can be repeated on the same battery recovery capacity operation, both to extend battery life, but also conducive to environmental protection.
The invention has been tested on smartphones, but the change in the electric car industry is even more significant because most people may switch to a cell phone in two years, but the car will take more than a decade.
It is reported that, Industry giants such as Apple, Samsung and Panasonic are both interested in the invention.
