quantum leap!New nanotechnology can double the life of high-voltage lithium-ion batteries

Researchers at the University of Queensland (UQ) have reportedly developed a new nanotechnology that is said to more than double the life of high-voltage lithium-ion batteries, paving the way for higher-density and lower-cost energy storage solutions.

A team of UQ researchers designed an atomic, thin cathode material to reduce corrosion in lithium-ion batteries and improve its high-pressure cycle stability, with capacity retention of nearly 80 percent after 1,000 cycles.The results, recently published in the journal Nature Communications (Nature Communications), said he and his team from the School of Chemical Engineering and the Australian Institute of Bioengineering and Nanotechnology (AIBN) have shown a rechargeable lithium-ion battery that remains stable over more than 1,000 cycles.

"We have designed a unique atomic thickness functional layer on the high-pressure cathode surface, which is the source of lithium ions and a key factor limiting the cycle life of batteries.This new approach features the use of a minimal protective coating in scalable processes, paving the way for the use of these rich high-pressure materials in next-generation high-energy batteries."He said.He further explained that the main cause of battery degradation is some form of corrosion, but that the new process will improve the battery life of all products, from smartphones to electric cars.It is understood that the new technology involves the application of epitaxial engineering wet layer on lithium nickel-manganese oxide (LNMO) cathode materials.The team says the atomically thin wetting layer can dissolve the transition metal from the cathode over the long term without affecting its power.

As the industry faces increasing pressure to decarbonize, developing lithium-ion batteries with lower cost, higher energy density and longer cycle life is crucial, ng said."We are confident that nanotechnology will have a wide range of applications across the industry, including consumer electronics, electric vehicles and energy storage.”

Domestic battery technology expert: Shenzhen Sanmu New Energy said: " Using epitaxial surface layers to improve the cycle efficiency and cycle life of high-voltage cathode are critical to improving the energy density of lithium-ion batteries, and the method developed here may also stabilize other cathode materials that can degrade rapidly with circulation."At the same time, the relevant feasibility will be studied in depth simultaneously
