Lithium has faced some backlash but has also garnered a lot
of demand recently. With lithium-ion recently hitting the market, the energy
density of which is higher than nickel-cadmium battery, is the lithium-ion best
of the battery? Let’s find out!
In lithium ion batteries the load character is amazing, its
discharge is better than nickel cadmium. Its high cell voltage helps the
battery pack for more energy in one cell. Unlike most forms of batteries,
lithium ion batteries require no memory or schedule cycling to prolong and
reset its battery life.
However, there is a minor drawback. That is, these batteries
are fragile and require a circuit protection for safe operation. The protection
puts a cap on the peak voltage during charging hours and prevent voltage
dropping during discharge. Cell temperature is also monitored closely. Despite
this, there is a risk of metallic lithium plating to occur.
Another concern that lingers in the mind of the consumers
relate to the age of the battery. It has been observed that despite non-usage,
there is a bit of capacity deterioration noticeable after a year. After 2-3
years, the battery fails frequently.
Due to these shortcomings, manufacturers are constantly
working on ways to improve lithium-ion batteries by introducing ground-breaking
and never experimented chemical combinations. With so many combinations being
invented daily, computing the age of the battery becomes difficult.
To slow the aging, manufacturers have recommended
lithium-ion batteries to be stored at below 15 degree Celsius. Battery must
remain at or above 40% charge at all times during storage.
Here is a list of advantages that make a lithium ion battery
a guaranteed winner:
- Potential for yet higher capacities. Potential for higher capacity battery due to better energy density.
- Does not demand priming except for one full charge at the start.
- Almost non-existence self-discharge when compared with nickel-based batteries.
- Low to Zero Maintenance
