402030 polymer battery

New study confirms how lithium-rich cathode materials for high-energy electric vehicle 402030 polymer battery store charge at high temperatures

 

High-energy 402030 polymer battery for electric vehicles require high-capacity battery cathodes. New lithium-excess magnesium-rich cathodes are expected to replace existing nickel-rich cathodes, but understanding how magnesium and oxygen adapt to charge storage at high voltages is crucial to their successful adaptation. Research led by WMG at the University of Warwick, in collaboration with researchers in the United States, conducted a series of X-ray studies to determine that oxygen ions, rather than magnesium ions, are promoting charge storage.

 

Only electric vehicles will be in production by 2030, which means manufacturers are racing to make high-energy 402030 polymer battery that are affordable and rechargeable efficiently, but conventional battery cathodes cannot reach the 500Wh/Kg target

 

Lithium-excess cathodes are capable of 500Wh/Kg, but unlocking their full capacity means understanding how charge is stored at high voltages.

 

A new X-ray study led by WMG at the University of Warwick has solved the question of how metals and oxygen facilitate charge storage at high voltages.

 

Electric vehicles will one day dominate the roads and will be crucial to eliminating CO2 emissions, but the main problem facing car manufacturers is how to make an affordable, long-lasting, high-energy-density battery that can be charged quickly and efficiently. As a result, there is a race to create EV 402030 polymer battery with 500Wh/Kg energy storage targets, but these targets are impossible to achieve without new cathode materials.

 

Despite continuous progress over the past 10 years to push the performance of state-of-the-art nickel-rich cathodes for electric vehicles, the material has not been able to provide the required energy density. To increase capacity, more lithium needs to be used, which means exceeding the nickel's ability to store electron charge.

 

Lithium-rich magnesium-rich cathodes offer adequate energy density, but to ultimately reach the 500Wh/Kg energy storage target, we need to understand how the electron charge is stored in the material. In short, it is the electron charge stored on magnesium or oxygen sites.

 

In the paper "Is manganese oxidized in manganese-rich alkaline excess cathodes?" published today in ACS Energy Letters, researchers from WMG at the University of Warwick have overcome a major milestone in understanding the lithium-excess magnesium-rich cathode.

 

Lithium-excess compounds involve both conventional and unconventional redox reactions, with conventional referring to metal ions that change their electron density. Unconventional redox reactions are those that reversibly change electron density on oxygen (or oxygen redox) without forming oxygen. Various computational models involving different mechanisms of both mechanisms are described in the literature, but careful X-ray studies while the battery is cycled (operando) are ultimately needed to validate these models.

 

Researchers between the UK and the US, led by WMG at the University of Warwick, performed operando X-ray studies to precisely quantify magnesium and oxygen species at high pressures. They demonstrated how an X-ray beam can irreversibly drive highly oxidized magnesium (Mn7+) to irreversibly adsorb oxygen into other materials.

 

However, by performing careful operando X-ray studies, beam damage was avoided and only trace amounts of Mn7+ formation were observed during battery cycling when charging in a lithium-excess cathode.

 

Professor Louise Piper of WMG at the University of Warwick explains:

 

"We have finally solved the problem that oxygen, rather than metal redox, is driving the higher capacity, which means we can now design better strategies to improve the cycling and performance of such materials."
