Many electric vehicles are powered by lithium batterie that rely on cobalt—a scarce, expensive metal with high environmental and social costs. A team of researchers from Japanese and French universities has now developed a practical nickel-based electrode material that opens new avenues to cobalt-free batteries for electric vehicles.

The researchers detailed their findings in a study published in the journal Energy Storage Materials.

“There is an undeniable need for cobalt-free, high-energy electrode materials for lithium batterie,” said Naoaki Yabuuchi from Yokohama National University.

Lithium batterie can be recharged when lithium ions flow from a positively charged electrode to a negatively charged electrode. In most lithium batterie for portable electronics, the positive electrode contains lithium cobalt oxide (LiCoO2), a chemical compound that offers high stability and energy density.

However, the limited, fraught supply chain of cobalt creates a bottleneck for large-scale batteries, including the ones used in electric vehicles. In addition, cobalt extraction generates toxic waste that contaminates land, air, and water.

To address these issues, lithium nickel oxide (LiNiO2)—which is similar in structure to LiCoO2—often serves as a cobalt-free alternative for electrode material. However, key instability issues plague the compound, specifically a gradual loss of capacity at the high-voltage region, which is associated with nickel-ion migration.

To improve electrode reversibility, nickel ions have been partially substituted by other metal ions, including reintroduced cobalt ions as well as manganese, aluminum and magnesium, to create “nickel-enriched layered materials” to serve as positive electrode materials.

li-ion-14.8v-12ah-battery-lithium batterie

“So far, 10–20 percent cobalt ions were necessary for nickel-based electrode materials,” Yabuuchi said. This, according to Yabuuchi, is still too much, and a unified understanding of how metal substitution can improve the process has not yet been established.

To address this knowledge gap, Yabuuchi and collaborators dug deeper into the problematic phase transition. When lithium ions leave the cathode under the influence of an external field, nickel ions migrate to specific sites within the lithium layers. Although this process is reversible, the reversibility gradually degrades through continuous cycles until the capacity is completely lost—a phenomenon not seen in cobalt-ion migration.

Previous studies reported that tungsten doping in LiNiO2 is an efficient approach to suppressing the detrimental phase transitions at high-voltage regions. Yabuuchi and collaborators tested the hypothesis that heavy, expensive tungsten ions could be substituted with other elements, specifically phosphorous—a lighter, more abundant element.

After detailed analysis on LiNiO2 integrated with nanosized lithium phosphate (Li3PO4), the researchers observed that, under certain conditions, problematic nickel-ion migration was effectively suppressed due to repulsive electrostatic interaction from the extra nickel ions within the Li layers.

Moreover, from these findings, Li-deficient LiNiO2, Li0.975Ni1.025O2, with the extra nickel ions in Li layers, is also synthesized using a simple methodology without phosphorus integration. Results also showed how Li0.975Ni1.025O2 can effectively mitigate unfavorable nickel-ion migration, and deliver consistent reversibility without cobalt ions.

“These findings open a new direction to develop high performance and practical cobalt-free nickel-based electrode materials with an extremely simple and cost-effective methodology,” Yabuuchi said. “This material achieved the ultimate goal for high-performance nickel-based electrode materials.”

In future endeavors, the researchers plan to investigate the feasibility of a nickel-free material to support lithium-ion batteries.

Compared to lithium batterie, Sodium-ion batteries still have a number of weaknesses that could be remedied by optimizing the battery materials. One possibility is to dope the cathode material with foreign elements. A team from HZB and Humboldt-Universität zu Berlin has now investigated the effects of doping with scandium and magnesium.

The scientists collected data at the X-ray sources BESSY II, PETRA III, and SOLARIS to get a complete picture and uncovered two competing mechanisms that determine the stability of the cathodes. Their research is published in the journal Advanced Materials.

Lithium batterie have the highest possible energy density per kilogram, but lithium batterie resources are limited. Sodium, on the other hand, has a virtually unlimited supply and is the second-best option in terms of energy density. Sodium-ion batteries (SIBs) would therefore be a good alternative, especially if the weight of the batteries is not a major concern, for example in stationary energy storage systems.

However, experts are convinced that the capacity of these batteries could be significantly increased by a targeted material design of the cathodes. Cathode materials made of layered transition metal oxides with the elements nickel and manganese (NMO cathodes) are particularly promising.

They form host structures in which the sodium ions are stored during discharge and released again during charging. However, there is a risk of chemical reactions which may initially improve the capacity, but ultimately degrade the cathode material through local structural changes. This has the consequence of reducing the lifetime of the sodium-ion batteries.

“But we need high capacity with high stability,” says Dr. Katherine Mazzio, who is a member of the joint research group Operando Battery Analysis at HZB and the Humboldt-Universität zu Berlin, headed by Prof Philipp Adelhelm. Spearheaded by Ph.D. student Yongchun Li, they have now investigated how doping with foreign elements affects the NMO cathodes.

Different elements were selected as dopants that have similar ionic radii to nickel (Ni 2+), but different valence states: magnesium (Mg 2+) ions or scandium ions (Sc 3+).

14.8V 4Ah Li Ion Customized Battery Packs-lithium batterie

Three years of experiments at BESSY II, PETRA III, and SOLARIS

To decipher the influence of the two elements, they had to carry out experiments at three different X-ray sources.

At BESSY II, they analyzed the samples using resonant inelastic X-ray scattering (RIXS) and X-ray absorption spectroscopy (XAS) in the soft and hard X-ray ranges; at PETRA III, they evaluated structural changes with X-ray diffraction (XRD) and pair distribution function analysis (PDF) with hard X-rays, and for more detailed insights on the element magnesium, they carried out additional soft XAS investigations at the PIRX beamline at SOLARIS.

“The results surprised us,” explains Mazzio. Although doping with scandium leads to fewer structural changes during the electrochemical cycle than doping with magnesium, it does not improve stability. “Until now, it was thought that suppressing phase transitions (and thus volume changes) would also improve the cathode material cycling performance over many cycles. But that’s not enough.”

Magnesium doping suppresses the oxygen redox reaction in NMO even more. This was also unexpected, as magnesium is known to trigger an oxygen redox reaction in layered manganese oxides. “We analyzed different Mg/Ni ratios in NMO and found that the oxygen redox reaction reaches a minimum at a ratio close to 1,” explains Mazzio.

“Only through a combination of advanced X-ray techniques could we show that it is more than just suppression phase transitions that are important for improving the long-term cycling behavior, but also the interplay between Ni and O redox activity dictate performance.”

It’s recommended to keep the depth of discharge between 20% and 80%. Deep discharge accelerates battery aging, so limiting the DoD helps extend battery life.

Avoid Overcharging: Control charging voltage and rate rigorously to prevent overcharging. Excessive charging voltage can lead to electrolyte decomposition and internal stress, reducing battery lifespan.

Effective Temperature Management: Ensure LiFePO4 batteries operate within the appropriate temperature range. High temperatures accelerate battery aging, while low temperatures reduce battery performance. Avoid exposing batteries to extreme temperature conditions and take measures to maintain optimal operating temperatures.

Minimize Frequent Charge/Discharge Cycles: Reduce unnecessary charge/discharge cycles as frequent cycling accelerates battery aging. Minimizing these cycles helps prolong battery life.

Utilize Advanced Battery Management Systems (BMS): Implement BMS to monitor battery status and adjust charging/discharging processes accordingly. This optimization maximizes battery performance and lifespan.

Avoid Vibration and Mechanical Stress: Vibrations and mechanical stress can damage LiFePO4 battery internals, leading to performance degradation. Minimize exposure to severe vibrations during installation and use.

Regular Maintenance and Inspection: Perform regular inspections and maintenance on LiFePO4 batteries. Ensure connectors and wiring are in good condition, clean battery surfaces, and check for any abnormalities. Regular maintenance allows for early detection and resolution of issues, prolonging battery lifespan.

In summary, through prudent control of charge/discharge cycles, temperature management, and the use of battery management systems, LiFePO4 battery lifespan can be maximized while optimizing charge/discharge performance.

And in some areas, like North America, North Europe, the temperature in winter is always lower than 32°F (0°C). How can they use the battery properly in winter, such as charging and discharging, below 32°F (0°C)? This is a practical problem that customers will meet.

Himax 12V 6000mAH lifepo4 battery

As we know, conventional lithium-ion batteries or LiFePO4 battery cannot be charged at temperature below 32°F (0°C).

Gladly, the heating film can help to solve this problem. When the temperature is below 32°F (0°C), the heating film will be turned on under charging conditions. During heating , the charger only supplies power for the heating film and it will not charge the battery. When battery heats up to 50°F (10°C), the BMS stops heating and the battery starts to charge. When storaging and discharging, the heating film neither works nor consumes battery power.

Currently, our 12V 100Ah/25.6V 100Ah/51.2V 100Ah LiFePO4 battery bank, or other AGM replacement battery can be equipped with a heating pad, which can help to solve the charging problem when temperature below 32°F (0°C).
