Li-ion batteries pack the most power per unit volume, but excessive charging or discharging can damage or destroy the battery and its surroundings. Carefully designed circuits help you avoid such dire outcomes.
Lithium-ion (Li-ion) batteries are now the popular choice for applications that require the highest concentrations of available power, both per unit volume and per unit weight. These batteries can store more energy than NiCd, nickel-metal hydride (NiMH), and other rechargeable types. Battery manufacturers developed Li-ion technology to avoid the problem of the volatility of metal lithium (see box, "Why lithium?"). The absence of lithium metal exempts Li-ion ...
