As the global lithium battery industry enters 2026, it is becoming increasingly clear that manufacturing capability—not laboratory-level electrochemical breakthroughs alone—will determine which technologies succeed at scale. Over the past decade, lithium-ion battery performance improvements were primarily driven by materials innovation: higher-nickel cathodes, silicon-doped anodes, improved electr...

Introduction: Why Battery Laboratory Design Matters More Than Ever in 2026 In 2026, lithium battery laboratories are no longer isolated research spaces dedicated only to material discovery. They have become critical engineering bridges between fundamental electrochemistry and industrial-scale manufacturing. Over the past five years, battery innovation cycles have shortened significantly....

Electrode slurry preparation is one of the most critical yet underestimated steps in lithium-ion and sodium-ion battery manufacturing. Problems such as particle sedimentation, agglomeration, poor dispersion uniformity, and unstable viscosity often originate at the slurry stage, but their consequences propagate downstream into coating defects, capacity inconsistency, and yield loss. This artic...

As the global battery industry seeks alternatives to lithium-based chemistries, sodium-ion batteries have steadily moved from academic research into early-stage commercialization. Among various cathode candidates, NFPP (Na₃Fe₂(PO₄)₃) has gained increasing attention due to its balanced performance, structural stability, and supply-chain advantages. Rather than pursuing extreme energy density, NFPP ...

The global race for the next generation of energy storage is centered on Solid-State Batteries (SSBs). While the potential for higher energy density and enhanced safety is clear, the transition from lab-scale prototypes to mass production remains a challenge. One of the most critical hurdles is ensuring perfect interface contact between solid electrolytes and electrodes. To bridge this gap, we are...

In all-solid-state batteries, the liquid electrolyte is replaced by a solid-state electrolyte membrane. Consequently, the front-end production process requires the preparation of this solid electrolyte film in addition to the traditional positive and negative electrode sheets. This process is a critical link in the battery manufacturing workflow, directly determining the performance and quality of...

On the production frontlines of lithium battery slurry mixing, coating, and subsequent assembly, slurry sedimentation, gelation (jelly-like consistency), and coating head blockages are three persistent "ailments" that trouble process engineers. These issues can further trigger chain reactions like electrode cracking, film delamination, and battery deformation. Such instabilities not only lead to p...

Ⅰ. Performance Advantages and Challenges of Silicon-Carbon Anode Materials (1) Electrochemical Characteristics of Silicon In lithium-ion battery anode research, silicon attracts significant attention due to its extremely high theoretical specific capacity. Upon full lithiation, silicon can form alloys with a specific capacity reaching 4200 mAh/g, nearly ten times that of conventional graphite. Thi...

Defects in lithium-ion battery coating originate from three main parts: the coating slurry, the coating window, and the coating drying process. In the slurry preparation process, incomplete dispersion introduces agglomerated particles; insufficient iron removal filtration introduces metal debris; and incomplete vacuum deaeration leaves behind numerous bubbles. Corresponding coating defects include...

The lithium battery separator acts as a protective barrier between the positive and negative electrodes, conducting ions but not electrons. In the ideal state after electrolyte filling and formation, the separator should maintain complete and flat contact with the electrodes. However, when we disassemble batteries, we often find severe wrinkling of the separator. (This can also be clearly observed...
