Comprehensive Insights into Lithium-ion Battery Technology
Lithium-ion batteries operate based on the movement of lithium ions between a positive (cathode) and negative (anode) electrode. During discharge, lithium ions travel from the anode to the cathode, generating an electric current. The process reverses during charging. The electrolyte, a lithium-ion-conducting medium, facilitates this ion transport. The specific materials used in the electrodes determine the battery’s performance characteristics. Different chemistries offer varying energy densities, cycle lives, and safety profiles. Sourcing reliable suppliers is crucial, as detailed on www.sourcifyChina.com.
