Do not short-circuit, overcharge, crush, drop, mutilate, penetrate, apply reverse polarity, expose to high temperature, or disassemble. Its relatively high cell voltage (2.7V to 4.2V) allows one-cell battery packs.Įxercise caution when handling and testing Li-ion batteries. Besides high capacity, the load characteristics are reasonably good and behave similarly to the NiCd in terms of discharge characteristics. Li-ion energy density is about twice that of the standard NiCd. The Li-ion battery is safe, provided certain precautions are met when charging and discharging. Lithium-ion batteries have the greatest electrochemical potential and the highest energy density per weight. Popular rechargeable batteries are nickel cadmium (NiCd), nickel-metal hydride (NiMH), lithium-ion (Li-ion), and lithium-polymer (Li-pol). Primary battery examples are alkaline and lithium metal cells. To meet these design objectives, the power-management subsystem design begins with the battery, which may be a non-rechargeable primary battery or a rechargeable secondary battery. A typical battery-based power-management subsystem consists of single or multiple-function ICs.
