Overview：Lithium-ion batteries share some similarities with NiCad (nickel-cadmium) batteriessimilarities. Both types of batteries are rechargeable and optimal for certain applications. However, they also have great differences.
Lithium-ion batteries share some similarities with NiCad (nickel-cadmium) batteriessimilarities. Both types of batteries are rechargeable and optimal for certain applications. However, they also have great differences.
Lithium-ion batteries have various applications and are often plugged in portable electronic devices such as walkmans, game boys, laptops, digital cameras and mobile phones. Nowadays, we can find high energy density battery for smartwatch. Many portable power tools and two-way radios use nickel-cadmium batteries. Compared to nickel-cadmium batteries, li-ion batteries are also widely used in wearable devices — wearable rechargeable lithium ion battery.
2. Memory Effect
According to a recent report, "memory" is an effect that have influence on some types of batteries. There are large crystals forming on cell plates when some types of batteries are not periodically discharged. This accumulation can result in a decrease of the battery electrical storage area. Nickel-cadmium batteries, unlike lithium-ion batteries, are easily effected by the "memory effect."
3. Shelf Life
Both types of batteries have relatively long working lives. Nickel-cadmium batteries can be stored or used for up to 5 years. Lithium-ion batteries can last for 2 or 3 years.
If they are properly maintained, nickel-cadmium batteries are abble to provide you with more than 1,000 charge and discharge cycles. Lithium-ion batteries can offer between 300 and 500 charge and discharge cycles.
According to a recent report, nickel-cadmium batteries have a higher rate of self-discharge than high discharge rate lithium ion battery. NiCad batteries will need to be recharged if they have full energy storage but are idle without use for several months. Lithium-ion batteries on the other hand, can go unused for several months before they begin self-discharging.
Normally, lithium-ion batteries operate at higher voltages compared to nickel-cadmium batteries. 3.7 volt lithium battery is a typically used in daily use and a nickel-cadmium battery operates at 1.2 volts.
