Lithium polymer battery technology is more advanced than lithium-ion batteries. It didn’t appear until the 1970s and has only been installed in smartphones in recent years. For example, Samsung only switched to lithium polymer in the Galaxy S20 series, while other manufacturers used the technology earlier. And Samsung used lithium-ion back on the Galaxy Note 20 series.
Lithium polymer technology also uses positive and negative electrodes but uses dry solid, porous chemical, or gel-like electrolytes instead of liquids. Therefore, polymer batteries can provide a lower profile, flexible, and more robust design, and the possibility of electrolyte leakage causing thermal runaway is lower. In short, they are safer.
A significant disadvantage of this technology is that the manufacturing cost is significantly higher. The life cycle of lithium polymer is also shorter, and the energy stored in the battery is less than that of a lithium-ion battery of the same size. These batteries still need to rely on protection circuits to keep the voltage running within a safe range.
