"𝐈𝐟 𝐲𝐨𝐮'𝐫𝐞 𝐠𝐨𝐢𝐧𝐠 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐡𝐞𝐥𝐥, 𝐤𝐞𝐞𝐩 𝐠𝐨𝐢𝐧𝐠." 𝑊. 𝐶ℎ𝑢𝑟𝑐ℎ𝑖𝑙𝑙 Even during these unbearable days, we were able to publish our latest research on anode-free lithium-metal batteries at ECS - The Electrochemical Society (open access). Among our findings, we discovered that conducting EIS measurements during early battery cycles can degrade cyclability. Additionally, using a Cs-based salt additive prevents the formation of "dead-lithium" inside the SEI and improves the cycle life of the cell.

🔋 A recent study using high-resolution resonant inelastic X-ray scattering (RIXS) has uncovered the reasons behind voltage fade in lithium-rich battery cathodes. 🔎 The research, conducted by Diamond Light Source, the University of Oxford, and the The Faraday Institution's CATMAT project, found that the gradual increase of electrochemically inactive O₂ and the loss of O₂ from voids near the cathode surface lead to a reduction in the oxygen redox capacity, causing the voltage fade. ⚡🚗 Understanding and addressing this issue is crucial for improving the energy density and performance of lithium-ion batteries, which are essential for electric vehicles and the transition to low-carbon energy sources. The insights gained could lead to innovations in cathode chemistry, enhancing the performance and lifespan of next-generation lithium-ion batteries.

Great work by Diamond Light Source, University of Oxford & #CATMAT project on uncovering the cause of voltage fade in lithium-rich battery cathodes. "It shows us that there is less and less oxygen redox as the battery cycles, so the battery becomes less and less effective. We’ve found two causes for this drop. The first is that some of O2 isn’t fully reduced back to oxide on the discharge cycle, which leaves residual O2 trapped in the material. The second is that O2 is escaping from the cathode." "High resolution RIXS at I21 has proved to be a tremendously powerful tool for investigating oxygen redox in Li-rich materials. There are very few techniques that allow you to detect O2 when it’s trapped inside a material, and that’s why RIXS is critical to understanding next-gen battery materials."

I recently had the opportunity to review a manuscript for the journal Ionics, titled "Capacity prediction method of lithium-ion battery in production process based on extreme gradient boosting." It was a pleasure to contribute my insights to this exciting area of research, which holds great potential for improving battery performance and efficiency in industrial applications. I look forward to seeing the final outcomes of this work and continuing to engage with the scientific community through similar contributions. #LithiumIonBatteries #BatteryTechnology #PeerReview #Research #XGBoost #Energy

All-solid-state lithium-ion batteries offer higher energy density and safety due to non-flammable solid electrolytes, but face challenges like low Li-ion conductivity and electrode-solid electrolyte contact. Scientists from Tokyo University of Science have now discovered a stable, highly conductive lithium-ion conductor in the form of a pyrochlore-type oxyfluoride, Li2-xLa(1+x)/3M2O6F (M = Nb, Ta). This study, published in the Chemistry of Materials, addresses the need for non-sulfide solid electrolytes and paves the way for advanced all-solid-state lithium-ion batteries with improved performance and safety.

Its not uncommon to see a news story about Lithium batteries exploding or catching fire - Airlines have made it a regular protocol to keep these out of checked bags to avoid a catastrophe at 30,000 ft. Many of us will charge devices unattended and (hope) that a fire does not occur. With energy storage and portability on the rise, these clever researchers at Cornell have come up with a new structure that gets to the root of why these batteries are dangerous in routine use, especially when charging. Seems like the core solution is creating a molecular structure that is even and allows the Li ions to pass freely without binding up and shorting the current. These chemists created a fusion process with molecular cages and macrocycles to produce these new structures for battery development. The novel idea is also shedding light on other ion-transport possibilities such as desalination or bio circuits. #cornelluniversity #lithiumionbatteries

Researchers have shown that the surface morphology of catalysts significantly influences their electrocatalytic performance. By examining platinum surfaces, they discovered that rough, high-surface-area structures enhance activity in hydrogen evolution reactions. This finding underscores the importance of designing catalysts with optimized surface features to improve efficiency in various electrochemical processes. Understanding and controlling surface morphology could lead to more effective and durable catalysts for energy conversion and storage technologies.
