A Great Leap Forward In Lithium Battery Technology, Old Battery Can Restore 95% Capacity
Jan 17, 2018

It is well known that the capacity of lithium-ion batteries drops to 80%~85% after 300-500 charge and discharge cycles, and new batteries must be replaced to restore initial endurance. Researchers at Nanyang Technological University (NTU) in Singapore recently claimed to have invented technology to restore 95% of capacity to lithium-ion batteries. The new technology, which allows old batteries to rejuvenate quickly, will have a profound impact on the electronics and electric-vehicle industries.

Professor Rachid Yazami of NTU said his invention can restore the old lithium battery to 95% capacity within 10 hours, and can repeatedly restore capacity operations on the same battery every few years, which will greatly improve the life of lithium-ion batteries used in electronic equipment and electric vehicles, Can greatly reduce the waste of lithium-ion batteries, so that lithium batteries more environmentally friendly.

After the invention was published, industry giants including Apple, Samsung and Panasonic have expressed keen interest in the invention. The invention adds a third electrode between two electrodes already in each lithium-ion battery, and a third electrode discharges the remaining lithium ions from one pole to another, removing the "impurity content" that affects the battery's ability to stop the battery from storing more electrons, and has been tested successfully on the prototype smartphone. For battery manufacturers, however, this may not be a good thing, and it is likely to deliberately delay the large-scale adoption of the technology.
