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.

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.

Why Can Lithium-Ion Batteries Explode? Detailed Examination of Underlying Causes

high quality li ion battery

Introduce

Lithium-ion batteries power a vast array of devices and are celebrated for their high energy output and rechargeability. However, their capability to store a large amount of energy in a small space also brings significant risks, particularly the risk of explosions, which, while rare, can have severe consequences.
  1. Thermal Runaway Explanation:
    1. Chemical and Physical Causes: Thermal runaway is primarily a result of chemical reactions that generate excessive heat; this can be triggered by several factors. When the internal temperature of a lithium-ion battery rises to a point where the heat can no longer efficiently dissipate, it can cause the electrolyte and other battery materials to decompose and generate more heat. This runaway reaction is self-sustaining and accelerates once it begins.
    2. Cascading Failures Leading to Explosions: In thermal runaway, the breakdown of electrolytes releases gases that increase internal pressure. If the battery casing ruptures, it may expose the highly reactive lithium to oxygen, resulting in a fire or explosion.
  2. Internal Short Circuits:
    1. Mechanical Damage and Manufacturing Defects: Internal shorts are often caused by physical damage, such as dropping the device, or by flaws in the battery’s construction, such as poorly aligned electrodes or inadequate separator thickness. These defects can create conditions where the positive and negative electrodes contact directly, causing a short circuit.
    2. Effect on Battery Stability: Short circuits can rapidly increase internal temperature and pressure, overwhelming the battery’s built-in safety mechanisms and leading to a breach of the cell casing.
  3. Overcharging Risks:
    1. Charger Compatibility and Regulation: Using non-standard or incompatible chargers can lead to overcharging by failing to properly regulate the voltage and current flowing into the battery. Overcharging a lithium-ion battery can cause lithium metal plating on the anode, creating dendrites that can pierce the separator and create a short circuit.
    2. Battery Management System’s Role: A sophisticated battery management system (BMS) ensures that each cell within a battery pack is charged correctly and prevents cells from overcharging—a critical safeguard against thermal runaway and explosions.
  4. Flammable Electrolytes:
    1. Composition and Combustibility: The electrolytes in lithium-ion batteries typically consist of organic carbonates, which are flammable. Their role is to facilitate ionic movement between the electrodes, but when compromised, they pose a significant fire risk.
    2. Initiation and Propagation of Fire: If the battery casing is compromised and the flammable electrolyte is exposed to air or a spark, it can ignite. Moreover, once one cell catches fire, the heat can propagate to adjacent cells, escalating to a full battery pack explosion.
