In-depth analysis of cutting-edge battery technologies such as solid-state batteries, silicon-carbon anodes, high-nickel ternary, high-rate discharge systems, etc.
I. Introduction: Why Fast Charging Is a System Engineering Challenge With the rapid popularization of electric vehicles (EVs) and smart devices, the demand for “rapid energy replenishment” has become increasingly urgent. Whether it’s an EV that users expect to charge fully in ten minutes, or a smartphone that supports “plug-and-go” charging, fast-charging capability has become…
With the rapid development of electric vehicles, energy storage systems, and high-performance electronics, lithium-ion batteries with high energy density have become the core focus of research and industrial application. Among them, NCM811 (LiNi₀.₈Co₀.₁Mn₀.₁O₂) — a nickel-rich layered oxide — stands out due to its high specific capacity and energy density.However, NCM811-based batteries often face capacity…
In the battery industry, there is a topic that cannot be avoided—the winding process and the stacking process.They are the two core procedures in cell manufacturing, determining the energy density, lifespan, safety, and production efficiency of batteries. To make it easier to understand, let’s start with a simple analogy: Winding process is like rolling up…
