Researchers develop cobalt-free cathode for lithium-ion batteries

Researchers at the University of California, Irvine and four national laboratories have devised a way to make cathodes for lithium-ion batteries without the use of cobalt, a mineral that suffers from price inconsistencies and conflicts. of geopolitics.

In a paper published today in Nature, scientists describe how they overcame the thermal and chemical inconsistencies of cathodes that contain a large amount of nickel – a common substitute for cobalt – by combining them with other metallic elements deal.

Huolin Xin, co-author of UCI, said: “Through a technique we call the ‘high doping process,’ we succeeded in fabricating a cobalt-lined cathode with high temperature resistance and stability over repeated charging and recycling.” said author Huolin Xin, a UCI professor. of mathematics & astronomy. “This breakthrough solves the long-term safety and stability issues surrounding high-capacity battery materials, paving the way for more profitable commercial applications.”

Cobalt is one of the biggest supply chain risks threatening the adoption of electric cars, trucks and other electronic devices that require batteries, according to the paper’s authors. The mineral, which is chemically suitable for the stability of lithium-ion batteries, is mined only in the Democratic Republic of the Congo under conditions of abuse and deprivation.

“Electric vehicle manufacturers are trying to reduce the use of cobalt in their battery packs not only to reduce costs but also to address the child labor used in mining,” Xin said. “Research has also shown that cobalt can cause the release of oxygen at high voltage, causing damage to lithium-ion batteries. All this indicates the need for other methods.”

However, nickel-based cathodes come with their own problems, such as heat resistance, which can lead to oxidization of battery materials, thermal runaway and even explosion. Although larger nickel cathodes carry higher power, the increased power from repeated expansion and contraction can cause instability and safety concerns.

The researchers sought to solve these problems by means of complex doping by using HE-LMNO, a combination of transition metals of magnesium, titanium, manganese, molybdenum and niobium in the system, with part of these minerals and used on its surface and interface. with other battery materials.

Xin and his colleagues used a wide range of synchrotron X-ray diffraction, electron microscopy and 3D nanotomography equipment to confirm that their zero-emission cathode showed an unprecedented zero-emission shift when using repetition. The durable structure can withstand more than 1,000 cycles and high temperatures, which makes it similar to cathodes with a low nickel content.

For some of these research tools, Xin worked with researchers at the National Synchrotron Radiation Facility II, located at the US Department of Energy’s Brookhaven National Laboratory in New York. As a DOE Office of Science user, NSLS-II gave the team access to three of its 28 science instruments — called beamlines — to study the internal structure of the new cathode.

“The combination of different methods at the NSLS II beamlines made it possible to detect the trapping effect of oxygen vacancies and defects in the material, which prevents the explosion of the HE-LMNO secondary molecule, making this system very stable during ride a bike.” said colleague Mingyuan Ge, a scientist at NSLS-II.

Xin added: “Using these advanced devices, we were able to observe a significant increase in temperature and the temperature change of the cathode, and we were able to demonstrate improved capacity and cycle life. This research will ability to set up. the level of providing a large-scale alternative energy to existing batteries.”

He said the project represents a step towards achieving the two goals of encouraging the spread of clean transportation and saving energy and solving the problems related to the environment in the extraction of minerals used in batteries.
