SAMSUNG ORIGINAL BATTERY

$0

Original Samsung battery technology—developed and manufactured primarily by Samsung SDI—spans from the removable Lithium-Ion (Li-ion) packs of early mobile devices to advanced high-density Lithium-Polymer (Li-Po) and high-nickel NCA (Nickel Cobalt Aluminum) chemistry.Core Specifications & ChemistryCell Chemistry: Utilizes high-density Lithium Cobalt Oxide ($\text{LiCoO}_2$) or high-nickel NCA/NCM active cathode materials paired with a graphite (or emerging silicon-carbon composite) anode to deliver high energy density and stable nominal voltages around 3.7V–3.85V.Form Factor & Construction: Transitions from legacy removable rigid prism/pouch cells housed in hard plastic cases to ultra-thin, integrated pouch cell designs using gel-polymer electrolytes for thin flagships and foldables.Protection Circuit Module (PCM): Integrated safety board containing micro-IC controls to prevent overcharging, over-discharging, short-circuits, and thermal runaway.
