II. Overview of Lithium Battery Cells
2.1 Working principle of lithium-ion batteries
As the core component of a lithium battery, the lithium‑ion cell operates on the principle of the directional migration of lithium ions between the positive and negative electrodes. During charging, lithium ions desorb from the positive electrode material, travel through the electrolyte to the negative electrode, and intercalate into its crystal lattice; during discharging, the reverse occurs: lithium ions deintercalate from the negative electrode, migrate back to the positive electrode via the electrolyte, and electrons flow through the external circuit, generating an electric current and enabling the mutual conversion of chemical energy and electrical energy.
2.2 Comparison of the Characteristics of Ternary and Lithium Iron Phosphate Cells
Ternary lithium battery cells use nickel, cobalt, and manganese ( NCM ) or nickel-cobalt-aluminum ( NCA ) and other multi-component materials as the cathode, offering a high energy density; current mainstream products can achieve an energy density of up to 180 - 260 Wh/kg It can deliver longer driving ranges, meeting consumers’ demand for extended range; however, its thermal stability is poor, making it prone to thermal runaway under high-temperature conditions or in the event of an internal short circuit, which poses a relatively significant safety risk. Moreover, due to its reliance on scarce metals such as nickel and cobalt, its cost is highly sensitive to fluctuations in raw-material prices.
Lithium iron phosphate cells use lithium iron phosphate ( LFP ) Used as the positive electrode, it features a stable crystal structure, excellent thermal stability, a wide operating temperature range, and resistance to decomposition at high temperatures, resulting in extremely high safety. Its energy density typically falls within 140 - 180 Wh/kg Although its energy density is lower than that of ternary lithium cells, it is sufficient to meet the demands of most short- and medium-distance travel scenarios. Moreover, its raw materials are widely available, and its cost is primarily driven by lithium carbonate, which remains relatively stable. With no reliance on scarce and expensive metals such as cobalt, it boasts a significant overall cost advantage.
