As the use of portable devices grows, so does the demand for reliable battery power. For this purpose, lithium-ion batteries are gaining popularity in the tech market. They are used in most portable devices like laptops and cell phones.
To better understand how they are better suited for these devices, tech experts have explained their numerous benefits and abilities;
“Lithium-Ion batteries are known for several key factors, one of which is how low maintenance they are. This makes it ideal to put in the hands of the average smartphone owner since there's nothing special required on their part to keep it functional. They're also compact and light, making them perfect to use in pocket-sized devices like mobile phones.” (Edward Eugen)
“Then there is the really high energy density, which is why Li-ion batteries can pack so much juice in such a small package, and last so long between charges. But eventually, when they do run out, they can be recharged rapidly and efficiently too. Limiting this downtime where the phone is plugged in is a key feature of many mobile phones.” (Edward Eugen)
“Another factor is that Li-ion batteries contain far less toxic metals compared to lead-acid or nickel-cadmium batteries, for instance. This makes it a much more eco-friendly option for mobile phone manufacturers to use in their devices.” (Edward Eugen)
“There is also a phenomenon that occurs with all batteries, known as self-discharge, which is when the batteries slowly lose their maximum charge capacity, even out of use. Li-ion batteries suffer from this the least compared to other types of batteries, which adds to their long shelf life.
With these factors in mind, there's no wonder why Li-ion batteries are the industry standard for mobile phones!”

“Lithium-ion batteries have the highest energy density (100-265 Wh/kg). Lithium-ion batteries charge more quickly and efficiently. This results in a more powerful battery than lithium iron phosphate batteries.
“Low-Maintenance: Compared to nickel-based batteries, lithium-ion batteries are simple to use and maintain. Nothing needs priming and no scheduled cycling is necessary to keep their batteries alive. They also have no memory effect, which reduces battery performance after repeated partial drain and charge cycles.” (Edward Mellett)
“Lithium-ion chemistry excels in high-power applications. They deliver more current than nickel-based batteries. They can deliver up to 3.6 volts, which is three times more than a nickel. Lithium-ion batteries have a long shelf life due to their low self-discharge rate (1.5-2%).” (Edward Mellett)
“Lithium-ion batteries are suited for many renewable energy applications. Other high-power uses for their technology include portable electronic devices, electronic automobiles (EVs), and aircraft.”

“Lithium-ion batteries contain fewer harmful heavy metals than lead-acid and nickel-cadmium (NiCd) batteries. Cadmium, lead, and mercury have long been used in batteries, but extended exposure and improper disposal endanger humans, animals, and plants. Even though Li-ion batteries are safer than many other batteries, they must be properly recycled.” (Chris Taylor)
“Lithium and carbon, the two most common electrodes in lithium-ion batteries, are lightweight, allowing for smaller and lighter batteries than lead-acid batteries. This feature of lithium-ion batteries is useful in head torches since we can enhance light output and runtime without adding size or weight to the battery pack (or your head!).
“High Energy Density: Lithium is a highly reactive element capable of releasing and storing huge amounts of energy, allowing li-ion batteries to be compact. As a result, lithium-ion batteries last far longer between charges than other rechargeable batteries while still performing well. To match the output of a single lithium-ion battery, three nickel-metal-hydride (NiMH) batteries are required.
“Low upkeep: Lithium-ion batteries don't have a memory effect, so you can recharge them whether you've used 100% or 25% of their capacity!” (Chris Taylor)
“Lithium-ion batteries have a 1000 charge cycle life. A full charge cycle occurs when the battery is depleted to 0% and then recharged to 100%. Using your battery to 75% capacity and then putting it in doesn't count. Only after a full charge cycle can you use the remaining 75% of your battery's capacity.
“Low Self-Discharge Rate: Lithium-ion batteries also self-discharge slowly. Self-discharge is a natural, irreversible phenomenon that occurs in batteries when they are not in use. After charging, the self-discharge rate of lithium-ion batteries peaks at around 5% and subsequently drops to 1-2% per month. Nickel-based rechargeable batteries, on the other hand, lose 10-15% of their capacity with each charge, and 10-15% per month.”

“Unlike lead-acid batteries, whose water levels need to be constantly checked, lithium-ion batteries don’t need to be watered, reducing the maintenance required to keep these batteries operational and eliminating engine maintenance from leakages.” (Harriet Chan)
“The batteries have a long lifespan that can last for as long as eight years or more. Also, their fast charging capabilities mean less downtime for machines tethered to charging stations and can be opportunity-charged. They also provide significant environmental benefits over other fossil fuel alternatives.” (Harriet Chan)
“Their cell voltage is higher at about 3.6volts, hence requiring fewer cells in many battery applications. For example, for a smartphone, only one cell is needed for easier power management. This voltage makes their load characteristics suitable by providing a constant 3.6 volts per cell before falling off as the last charge is used.”
