Restructuring the lithium-ion battery: A perspective on electrode architectures

Converting Residual Alkali into Sodium Compensation Additive for High-Energy Na-Ion Batteries

“…Generally, residual alkali is generated in the production process of layered oxide materials or when they are exposed to air/moisture. , The formed ionically/electronically insulated residual alkali species (NaOH/​NaHCO 3 /​Na 2 CO 3 ) lead to sluggish kinetic performance. Besides, the dissolution of residual alkali into N -methyl-2-pyrrolidone (NMP) causes a series of issues, such as gelation of the cathode slurry, corrosion of the current collectors, poor mechanical properties of the cathode, and gas production. , Therefore, the residual alkali species in layered oxide cathodes seriously affect their processability and electrochemical performance.…”

Recent advances and promise of MXene-based composites as electrode materials for sodium-ion and potassium-ion batteries

“…The excessive utilization of fossil fuels to foster economic growth has led to grave repercussions, notably climate change, making it one of the foremost contributors to energy scarcity and environmental pollution. 1–4 Addressing this pressing issue necessitates a focused quest for clean and renewable energy sources. 5–7 Nonetheless, effectively storing and sustaining conventional renewable resources, such as wind and solar energy, proves challenging.…”

Uniting Young's modulus and the flexibility of solid-state electrolytes for high-performance Li-batteries at room temperature

“…1–3 Solid-state batteries attract great attention thanks to their advantages compared to the traditional liquid lithium-ion batteries in terms of high safety and charge storage ability by using a lithium metal anode. 4–9 The key factor influencing the development of solid-state batteries is the solid-state electrolytes, which mainly include ceramics (sulfide and oxide) and polymers. 10–13 However, all of them face some problems; for example, sulfides are limited by being ultra-unstable in air and their serious side reactions with lithium metal, oxides are hindered by high interfacial impedance when contacted with electrodes, and polymers suffer from low ionic conductivity at room temperature.…”
