Which is safer, lithium batteries(Li-ion) or nickel metal hydride(Ni-MH) batteries?

NI-MH-Battery-Pack

Compared with lithium batteries(Li-ion), nickel-metal hydride batteries(Ni-MH) are superior in terms of safety.

Mainly because the specific heat capacity and energy density of nickel-metal hydride batteries(Ni-MH)are relatively low, but the melting point is as high as 400°C. When the nickel metal hydride battery is subjected to collision, extrusion, puncture, short circuit, etc., the temperature of the battery will not rise sharply and cause spontaneous combustion.

Ni-MH-battery-7.2v-3.3ah

After years of technological development, the mature manufacturing process and stable quality of nickel-metal hydride batteries have greatly improved the safety of the batteries.

In comparison, lithium batteries(Li-ion) are not as safe as nickel-metal hydride batteries, mainly because lithium ions(Li-ion) are more active and have higher energy density. At the same time, the raw materials of lithium batteries(Li-ion) are flammable. Once the battery is short-circuited due to various destructive factors and the temperature rises, the internal electrolyte will undergo a violent chemical reaction, which may cause the battery to spontaneously combust.

Investigating the origins of critical deformations in Li-ion batteries

Lithium ion batteries presently are the ubiquitous source of electrical energy in mobile devices, and the key technology for e-mobility and energy storage. Massive interdisciplinary research efforts are underway both to develop practical alternatives that are more sustainable and environmentally friendly, and to develop batteries that are safer, more performing, and longer-lasting—particularly for applications demanding high capacity and very dense energy storage.

Understanding degradations and failure mechanisms in detail opens opportunities to better predict and mitigate them.

In a new study, a team of researchers led by the Institute of Interdisciplinary Research of the CEA, the Institut Laue Langevin (ILL) and the European Synchrotron (ESRF) in collaboration has examined Lithium ion batteries during their lifetime using state-of-the-art, non-intrusive imaging techniques available at neutron and X-ray sources.

The team’s paper is published in the journal Energy & Environmental Science.

Neutrons and photons are largely complementary. Neutrons are particularly good at seeing lithium and other light elements, while X-rays are sensitive to heavy elements, such as nickel and copper. Their sophisticated combination allowed the researchers to gain multidimensional information on the components and elements inside working battery cells.

The team identified macroscopic deformations in the wound structure of the copper current collector. The deformed areas already existed in fresh battery cells that had only gone through the initial activation cycle (the first charging-discharging cycle). Further investigations revealed that these defects were due to local accumulations of silicon occurring during electrode manufacturing. Upon activation, the largest agglomerates expanded heavily, which led to deformations in the current collector, wasting capacity before the cell ever went into use.

 

sodium ion battery

It was possible to determine how large these accumulations must be to become a problem: cell structure and functioning is compromised for silicon agglomerations with a size above 50 microns. This is crucial information for both quality control and future developments. Erik Lübke, Ph.D. student at ILL and the main author of the study, summarizes, “In fact, resources are wasted when this happens, and we have quantified the effects and understood their causes.”

Full-field, high-resolution 3D transmission tomography enabled the inspection of the entire volume of the battery cell, revealing the presence of a number of defect features. These were more closely investigated at selected cross-sectional 2D slices.

The neutron tomography scans (with simultaneous low intensity X-ray computed tomography scans) were carried out at the NeXT instrument of the ILL. Synchrotron X-ray tomography scans of the very same cells were then measured at the ESRF using two beamlines, BM05 and the high-energy ID31 beamline for phase-contrast and scattering tomography respectively.

At NeXT, 3D high resolution neutron tomography is coupled with X-ray tomography to image the entire cell. Erik Lübke explains, “X-rays give the basic structure, making it possible to know exactly where we are when we use neutrons to examine the spatial distribution of lithium in detail,” benefiting from “the best neutron resolution you can get anywhere in the world.”

Selected parts of the cell were then examined in further detail using several different X-ray tomography techniques at the ESRF high-energy beamlines. Acquiring data during the battery charging process (a so-called operando experiment) made it possible to gather more information about the reaction dynamics in the defective regions: Lithium diffusion is partly blocked there, and even when most of the cell is fully charged these areas remain without lithium in their center.

To ensure the industrial relevance of the results, the team tested cylindrical silicon-based lithium ion battery cells manufactured according to industry standards. Cells of this format are in commercial use in small electronic devices such as medical sensors, headphones, and smart devices. However, the size was reduced for a better compatibility with the experimental requirements. Both fresh cells and aged ones (cycled over 700 times with roughly 50% remaining capacity) were imaged, in charged and discharged states. The different techniques were applied to the very same cells.

Current development status of sodium batteries

Himax - decorating image

Three years ago, sodium ion batteries emerged as a replacement to solve the problem of soaring raw material prices and production shortages for lithium batteries. And then gradually disappeared.

In 2022, against the background of soaring prices of lithium battery raw materials, the concept of sodium-ion batteries suddenly exploded. Major battery manufacturers have successively launched this kind of battery products.

However, in the past two years, the lithium battery industry chain has expanded production on a large scale, and the price of lithium batteries has dropped. The low-cost advantage of sodium-ion batteries has weakened, the technology is immature, and its performance is not as good as that of lithium batteries. Subject to energy density and cycle times, sodium-ion batteries are generally used in mini-cars and small cars.

portable device decorate img

However, sodium-ion batteries have a certain space for survival in the energy storage market. Because they can just meet the needs of energy storage batteries for low investment prices, safer safety, and long life. They may be deployed on a large scale in the future.

At present, many battery companies have abandoned their already developed electric vehicle product lines and switched to energy storage product lines. According to industry estimates, more than half of sodium battery companies have added new energy storage product lines. In addition, the academic community has also been insisting on the research and development of sodium batteries. It is expected to make a breakthrough in the energy storage market.

Scientists determine disorder improves lithium-ion battery life

18650 Battery 3.7V

What determines the cycle life of batteries? And, more importantly, how can we extend it? An international research team led by TU Delft has discovered that local disorder in the oxide cathode material increases the number of times  lithium ion battery can be charged and discharged. Their results have been published in Nature.

Rechargeable batteries are a key ingredient of the energy transition, especially now that more and more renewable energy is becoming available. Among the many types of rechargeable batteries, Lithium ion battery pack are among the most powerful and widely used ones.

To electrically connect them, layered oxides are often used as electrodes. However, their atomic structure becomes unstable when the battery is being charged. This ultimately affects the battery cycle life.

To solve this problem, the “Storage of Electrochemical Energy” group at TU Delft teamed up with international researchers. Qidi Wang, the paper’s lead author says, “The layered oxide used as cathode material for Li-ion batteries is neatly ordered. We conducted a structure design study to introduce chemical short-range disorder into this material through an improved synthesis method. As a result, it became more stable during battery use.”

Himax - decorating image

The improved structural stability almost doubled the battery’s capacity retention after 200 charging/discharging cycles. In addition, this chemical short-range disorder increases the charge transfer in the electrode, resulting in shorter charging times. The team demonstrated these advantages for well-established commercial cathodes such as lithium cobalt oxide (LiCoO2) and lithium nickel manganese cobalt oxide (NMC811).

The outcomes could lead to a new generation of Li-ion batteries, with a lower manufacturing cost and smaller CO2 footprint per unit of energy stored over its lifetime. The team will next investigate if the same material design principles can be used to build cathodes from raw materials that are less scarce.

“Both cobalt and nickel are so-called critical materials for energy technologies and it would be a good thing to reduce the use these materials in batteries,” says the paper’s senior author, Marnix Wagemaker.
