Key insights

🔋Lithium-ion batteries are composed of four major parts: cathode, anode, electrolyte, and separator. These components work together to facilitate the flow of lithium ions and electrons, allowing the battery to store and release energy.

💡Charge cycles impact a battery's longevity. As lithium ions shift back and forth within the battery, expansion and contraction occur, leading to performance degradation over time.

📦Lithium-ion cells can be packaged into different forms, such as cylindrical, prismatic, and pouch-style cells. Each form has its advantages and disadvantages in terms of cost, energy density, and power density.

The manufacturing process of lithium-ion batteries involves electrode manufacturing, cell assembly, formation, and pack assembly. The process includes mixing and coating electrode slurries, laminating and stacking cells, injecting electrolyte, charging, and discharging the cells, and finally assembling the battery packs.

🔬LG Energy Solution, with over 30 years of experience, has been actively researching and developing lithium-ion batteries. They have accumulated over 27,000 battery-related patents and continue to explore advancements in battery chemistry and solid-state batteries.
