New strategy improves performance of spent high-voltage lithium cobalt oxide batteries

In a study published in Advanced Materials, a research team led by Prof. Zhang Yunxia from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed an integrated bulk and surface commodification strategy to upgrade spent lithium cobalt oxide (S-LCO) batteries to operate at high voltages.

As the demand for high energy density storage devices grows, there’s a need to find sustainable ways to upgrade old LiCoO2 (LCO) batteries into more stable, high-voltage cathode materials.

In this study, the researchers developed a simple and effective method for upgrading LCO batteries. They used a combination of wet chemical treatment, heating, and a special phosphorus coating technique.

This process involved adding extra lithium, applying a uniform coating of lithium phosphate/cobalt phosphide (LPO/CP) to the surface, and incorporating manganese into the bulk material, along with a gradient of phosphorus near the surface. These modifications were all achieved simultaneously, resulting in significantly improved battery performance.

The result of these modifications is an improved LCO cathode, named MP-LCO@LPO/CP, which shows significantly improved electrochemical performance. The improved cathode exhibits high specific capacity and excellent cycling stability.

The researchers also investigated why the upgraded cathode performs so well at high voltages. They found that the modifications improve both structural stability and electrochemical properties, resulting in improved battery performance.

“This method is simple and easy to scale up, so it could also be used to recycle other waste cathode materials. This approach has great potential for the sustainable development of the lithium-ion battery industry,” said Prof. Zhang.

Do li ion batteries have memory

lithium ion battery pack

Understanding the Memory Effect in Batteries

Origins and Impact of the Memory Effect

The memory effect originally described a condition observed primarily in Nickel-Cadmium (NiCd) batteries, where they appeared to “forget” their full charge capacity if they were repeatedly recharged after being only partially discharged. This effect causes the battery to lose track of its full energy capacity, which could be misleading as to how much energy the battery could hold and deliver.
  1. Mechanism Behind Memory Effect:
    1. Formation of Memory: In NiCd batteries, if they are not fully discharged before charging, the areas of the battery that remain inactive start to form crystals. These crystals reduce the active material available for future discharges and charge cycles, effectively decreasing the usable capacity of the battery.
    2. Impact on Device Operation: For devices relying on these batteries, this could translate to shorter operational times after each charge, as the battery “thinks” it’s empty when there’s still unused energy left. This could lead to more frequent charging cycles, which in turn accelerates the wear and tear on the battery.
  2. Historical Context and Advances:
    1. Early Observations and Solutions: When the memory effect was first identified, it led to recommendations that users fully discharge their NiCd batteries before recharging them to “reset” the memory. This was a cumbersome process and not always practical for all types of devices, especially emergency equipment that needed constant, reliable power.
    2. Technological Responses: The inconvenience and operational inefficiency led to significant research into alternative battery chemistries that would not exhibit this problematic behavior, setting the stage for the development of lithium-ion batteries.

  1. Chemical Properties and Charge Management:
    1. No Memory Formation: Unlike NiCd batteries, lithium-ion batteries use a chemistry that does not lead to the crystallization of inactive areas during partial discharges. This is due to the movement of lithium ions in a liquid electrolyte between the anode and cathode, a process that doesn’t degrade the electrodes in a way that would create a memory.
    2. Efficient Charge Cycles: Lithium-ion batteries can handle partial discharge and recharge cycles without any significant loss in capacity. This flexibility makes them ideal for modern electronics that require frequent and varied usage patterns.
  2. Longevity and Performance:
    1. Cycle Life: Lithium-ion batteries typically have a cycle life of several hundred to several thousand cycles, with a gradual decrease in capacity. This degradation is uniform and predictable, unlike the abrupt and irregular capacity loss caused by the memory effect in NiCd batteries.
    2. Adaptability in Usage: The robustness of lithium-ion batteries in various discharge states makes them suitable for a wide range of applications, from mobile phones that are often charged overnight regardless of their remaining battery level, to electric vehicles that benefit from “top-up” charges without needing a full depletion of battery life.

Stable high-energy density lithium-ion batteries could lead to fast charging electric vehicles

12v 150ah lithium battery deep marine

A research team has developed a core technology to ensure the charging/discharging stability and long-life of lithium-ion batteries under fast-charging conditions. Their findings were published in Advanced Functional Materials.

A crucial prerequisite for the widespread adoption of electric vehicles (EVs) is the enhancement of lithium-ion battery performance in terms of driving range and safety. Fast charging is also essential for user convenience. However, increasing the energy density of lithium-ion batteries necessitates thicker electrodes, which can lead to battery degradation and performance deterioration during rapid charging.

To address this issue, the KERI team discovered a solution by partially coating the surface of the anode of the lithium-ion battery with aluminum oxide (Al2O3) particles smaller than 1 micrometer. While many researchers worldwide have concentrated on the materials within the electrode, such as introducing functional nanotechnology into anode materials like graphite, Dr. Choi’s team employed a straightforward processing technique to coat the electrode’s surface with aluminum oxide.

Low in cost, excellent in electrical insulation and heat resistance, chemically stable, and possessing good mechanical properties, aluminum oxide is widely used in various ceramics.

The KERI researchers found that aluminum oxide particles effectively control the interface between the anode and the electrolyte in lithium-ion batteries, forming an interfacial highway for efficient Li+ transport. This prevents the electrodeposition of lithium (an irreversible change that makes the lithium unavailable for additional charging and discharging) during fast charging, thereby ensuring the stability and lifespan of the lithium-ion battery during charging and discharging.

Another advantage of this technology is that it enables an increase in the energy density of lithium-ion batteries. Introducing other functional materials into the electrode’s interior to improve performance and stability often complicates the synthesis process and reduces the amount of reversible lithium (initial coulombic efficiency). It also increases the electrode thickness, leading to performance deterioration under fast charging conditions.

li-ion-battery

However, the KERI technology involves surface treatment of the graphite anode, rather than modifying the interior active graphite materials. This approach achieves stable performance even under fast charging conditions for high-energy-density thick-film electrodes without a loss in the amount of reversible lithium.

Through various tests, the team confirmed that the high-energy-density anode coated with aluminum oxide (4.4 mAh/cm2) exhibits world-class performance, maintaining more than 83.4% of its capacity (residual capacity ratio) even after 500 cycles of rapid charging. They have verified this performance with pouch cells of up to 500mAh. The team is now planning to scale up the technology to make it applicable to large-area, medium- to large-capacity cells.

The research team was led by Dr. Choi Jeong Hee at the Korea Electrotechnology Research Institute (KERI) Battery Materials and Process Research Center, in cooperation with a Hanyang University team mentored by Professor Lee Jong-Won and a Kyunghee University team mentored by Professor Park Min-Sik.

“Convenient fast charging and the energy density of lithium-ion batteries have long been considered a trade-off, which has hindered the widespread adoption of electric vehicles,” said Dr. Choi. “Our work will help develop stable, high-energy-density lithium batteries capable of fast charging. This advancement will contribute to the wider adoption of EVs and support the achievement of national carbon neutrality.”

Patents have been registered in both Korea and the United States.
