For decades, the majority of the consumers around the world are taught to use the conventional nickel-cadmium batteries for different electronic and electric devices which for many that time was the most suitable type of batteries especially for portable devices, wireless communications devices, and mobile computers.
However, nowadays, if you check the back of your smartphone or tablet, you will surely notice a brand new battery that powers it. This is the Lithium-Polymer (LiPo) or the lithium-ion batteries which is now mainly used in the majority of electronic and portable devices which is slowly taking over the world.
Before Lithium-ion and Lithium-polymer batteries were even introduced in the market, there were countless attempts to develop rechargeable lithium batteries but its developers faced a lot of failures especially when it comes to safety. Because of the unstable lithium metal, especially during its charging phase, its developers tried another option; using the non-metallic lithium ions as batteries, even though it has a lower power capacity, compared to lithium metal, it was proven safe otherwise and also it came with a certain precaution which all met with the standards of charging and discharging which then led to its first commercialization in 1991.
Later on, the lithium-ion batteries’ energy density grew twice that of the standard nickel-cadmium batteries, while there are more potential than its inventors discovered. One of the most notable advantages of using lithium-ion batteries is because of its low-maintenance, meaning there is no scheduled cycling required to prolong its lifespan whenever it is used. To add more, it is also a self-discharged compared to the nickel-cadmium that makes it very suitable for the modern fuel gauge applications with minimal hazards posed to it.
If you are already swayed by reading this article from rctopgeek about the advantages of a lithium-ion battery, just like any other technological innovations, it also has its own drawbacks. It is completely fragile which requires a lot of protective circuits to keep it safe from being used. Also, it is susceptible to peak voltage for each cell during its charge and can prevent cell voltage from dropping too low to discharge that will result to the rising temperatures of the battery which causes an explosion.
Also, one of the main concerns of the experts is the fast aging of lithium-ion batteries that its manufacturers keep silent about it. This kind of issue surrounds the capacity of the battery that deteriorates after a year, whether the battery is being used or not. The battery usually fails after three years of being used.
Despite its drawbacks, consumers and electronic brands did not let themselves held back by it, and instead manufacturers today continue to improve the quality and the safety of using lithium-ion battery because of its high energy density that is very ideal for higher capacity usage, while there is no requirement to priming when it is freshly purchased. Also, its low self-discharge keeps it more reliable than the half discharge of nickel-based batteries, and its low maintenance that does not require any discharge considering that it has its memory for it.
