A New Boron-Based Electrolyte for Better Magnesium Batteries #sciencefather #researcher #chemistry

🔋 Revolutionizing Magnesium Batteries: A Cost-Effective Boron-Based Electrolyte with Smart Interface Engineering

⚡ The Challenge:

Rechargeable magnesium batteries (RMBs) are strong contenders in the race for next-gen energy storage thanks to magnesium’s high abundance 🌍, enhanced safety 🛡️, and impressive volumetric capacity 📦. But there's a catch — creating boron-based electrolytes that are both efficient and scalable has been a long-standing bottleneck 🧪💸.

🧠 The Innovation:

A new magnesium phenyl fluoroborate complex (MPFBC) electrolyte offers a practical solution. Designed using cheap and accessible boron trifluoride 💰, MPFBC is synthesized through a simple Lewis acid-base reaction ⚗️, avoiding the need for complex or costly procedures.

🔧 Performance That Delivers:

This novel electrolyte enables:

• Stable cycling of Mg||Mg symmetric cells at 0.5 mA cm⁻² 🔁

• Low overpotential of <100 mV ⚡

• Long-term cycling with 62.6 mAh g⁻¹ specific capacity after 1000 cycles in Mg||Mo₆S₈ cells 🔋📈

🧬 Interface Engineering, Redefined:

What truly sets this work apart is its dual-mode interface regulation:

• Chemical process: In-situ pre-corrosion 🧪

• Electrochemical process: Formation of a Mg²⁺-conductive layer 🔌

Together, these strategies harmonize interface chemistry 🤝, making the Mg anode more stable and robust over time. This marks the first reported complementation of chemistry and electrochemistry to actively control the interface behavior in RMBs 🔄.

🌟 Why This Matters:

This development not only cuts down on costs 💸 and complexity 🧩, but also introduces a scalable path to commercialization 🚀 for boron-based electrolytes. It also enriches our scientific understanding of interface dynamics 🧠🔬 in multivalent batteries.

✅ The Takeaway:

With MPFBC and its novel interface strategy, we're a step closer to safe, affordable, and durable energy storage solutions 🌱🔋. It’s not just a material breakthrough — it’s a paradigm shift in how we approach electrolyte design and interface chemistry.
