ENERGY STORAGE LITHIUM-ION BATTERIES
Each Surplus Energy Generator system is equipped with a storage unit that includes an inverter. Li-ion batteries are chosen for their high energy density, low self-discharge, and lack of memory effect (except for LFP cells). However, caution must be exercised since they contain flammable electrolytes and can cause explosions or fires if damaged or charged improperly. The characteristics of lithium-ion batteries vary based on their chemistry, performance, cost, and safety. Lithium polymer batteries, which use a polymer gel as an electrolyte, lithium cobalt oxide (LiCoO2) as a cathode material, and graphite anodes, are commonly used in handheld electronics due to their high energy density. Lithium iron phosphate (LiFePO4), lithium manganese oxide (LiMn2O4 spinel, or Li2MnO3-based lithium-rich layered materials, LMR-NMC), and lithium nickel manganese cobalt oxide (LiNiMnCoO2 or NMC) are alternative options that may offer longer lifespans and better rate capability, making them ideal for electric tools, medical equipment, and other similar applications. Electric vehicles often use NMC and its derivatives.
