![[Analysis Case] Evaluation of Degradation of Lithium-Ion Secondary Battery Anodes](https://image.mono.ipros.com/public/product/image/237/2000010838/IPROS4163034357457498618.jpg?w=280&h=280)
Consistent evaluation from battery cell manufacturing, degradation testing, disassembly, to investigation of state changes due to degradation.
A degradation test was conducted on a battery cell made with LiCoO2 as the positive electrode, graphite as the negative electrode, and LiPF6/EC:DEC as the electrolyte, which was left in a constant temperature chamber at 60°C in a charged state of 4.2V for about one week. After that, the cell was disassembled and cleaned in an Ar atmosphere, and TOF-SIMS analysis of the negative electrode graphite was performed. Before the test, fragments derived from the binder and electrolyte salt were confirmed, and after the test, fragments such as Li3PO4 and PF3O, which are believed to have been generated due to the degradation of the electrolyte salt, as well as fragments from Li2CO3, were observed. Additionally, the detection of Co suggests the possibility of leaching of the positive electrode active material.

Case studies observed using X-ray CT.
Lithium-ion secondary batteries are widely used in devices such as smartphones and digital cameras. These batteries degrade through repeated charging and discharging, which can lead to the phenomenon of battery swelling. When investigating a battery that has experienced this phenomenon, there are concerns about reactions caused by gases or electrolytes accumulated inside, and since processing can be dangerous, it is necessary to confirm the internal structure non-destructively. In this case, the internal structure of a lithium-ion secondary battery that has undergone repeated charging and discharging was observed using X-ray CT.

Information on the energy barrier during Li-ion de-insertion and the solvent formation process can be obtained!
Our organization provides the energy profile of the Li-ion insertion and extraction process in LIB anodes/electrolytes using the ESM-RISM method. During the charge and discharge processes of lithium-ion secondary batteries (LIB), various phenomena occur near the interface with the electrolyte and the anode, including the formation of solvation, desolvation, the formation of the electric double layer, and the insertion and extraction of Li ions. This document introduces a case study that evaluates the energy profile and solvation structure during the Li-ion insertion and extraction process from graphite anodes using the hybrid ESM-RISM method, which combines Effective Screening Medium (ESM) and Reference Interaction Site Model (RISM) through simulation.

Button-type nickel-metal hydride rechargeable batteries with a track record of shipments primarily for backup applications in medical devices, industrial equipment, and automotive equipment.
Nickel-metal hydride batteries may be considered outdated with the advent of lithium-ion batteries. However, they have advantages over lithium-ion batteries in terms of safety and simpler peripheral circuit configurations. In particular, as a backup battery, they can be considered optimal because they allow for trickle charging. Additionally, they have advantages in terms of safety standards and air transport, making them worth considering as a main power source if size permits. If you are interested in nickel-metal hydride batteries, please feel free to consult with us.

Explaining the key points to consider when selecting a battery. This is easy to read even for those who are not familiar with batteries, covering types of batteries and their respective characteristics!
"Batteries" are products that are close to us. However, when it comes to choosing a battery, questions may arise such as: - How should I select a battery? - What points should I be careful about when using a battery? - What types of batteries are there in the first place? Even engineers may not be very familiar with batteries... This document has been created to be easily understandable for those who have never been involved in battery selection before. We encourage everyone involved with batteries to give it a read!

A hydrogen generation cell that produces gas without a power source! It's a new concept for a driving source that moves objects using the pressure of that gas. We would love to hear your ideas!
Speaking of batteries, they are generally products that convert chemical energy into direct current power through chemical reactions, using that power as a source for devices. Now, is it possible to conversely convert electrical energy into chemical energy? The product we are introducing this time is a unique hydrogen generation cell born from such an idea. No power source is required. The amount of gas (hydrogen) generated can be adjusted. Additionally, the generated gas can be used to move objects through its pressure. There are also applications that can utilize the high-purity hydrogen produced. Farta sees potential in this hydrogen generation cell. We look forward to innovative ideas from our customers that will help unlock the possibilities of this product, free from past usage cases! Farta Microbattery is a comprehensive battery manufacturer based in Germany. We also offer coin-shaped and cylindrical primary batteries in the CR series, nickel-hydrogen secondary batteries, lithium-ion battery packs, and more. If you are looking for batteries, please feel free to contact us.
