1. Is there an everlasting battery? What is the longest lasting battery?
In theory, batteries can be everlasting like Li-ion batteries, it can be everlasting as if their ion move back and forth with no disruption or reaction can produce and supply energy with their full potential forever. But, in reality, we can't say that there is long lasting battery because everything loses its ability or power with time. Even spring wears out over time while it only uses kinetic energy. Lithium-ion batteries are already the longest life of commercial batteries, usually up to 4,000 cycles.Therefore, compared with the shorter lead-acid battery and nickel-metal hydride battery, lithium battery can already be counted as long lasting battery.
However, there are another class of lithium-ion batteries that last longer: AA lithium battery(Do not have another brand name), which was 23% lighter than alkaline batteries, this battery has set a world record for the long lasting battery. They can hold power for up to 10 years and work in a temperature range of -20 to 60 degrees. Battery companies has used lithium-ion to make the long lasting battery, which has given the competitive advantage of weight, life span, and performance over the other batteries.
2. Do rechargeable batteries last forever?
Rechargeable batteries are the energy storage device that can charge and discharge the energy load onto the other device as a powerhouse of the device. And after its power is discharged, it can be recharged to supply power to the device as required. Still, Nothing can last forever, but rechargeable battery can be long lasting battery. For example, as discussed above,Lithium ion batteries weren't there to last forever,because the charging and discharging can make the batteries go bad. Still, these can be long-lasting batteries. And on the other hand, if the battery isn't used for a long time, it will affect the battery capacity and efficiency. While long lasting battery Lithium ion can last up to two or three years, with its full efficiency and powerfulness. But with proper maintenance and care of the battery may makeit a long lasting battery. For example, Lithium-ion polymer (LiPo) can last 10 year if it is charged and discharged on average once a day（4000/365≈10.96） with its total efficiency and performance if maintained and cared for properly.
3. Will lithium batteries last forever?
Lithium-ion batteries are the secondary batteries that use metallic lithium as an anode of their cell, making them a long lasting battery. Because of this, lithium-ion batteries stand apart from other batteries in their charging capacity and high prices. No doubt battery companies have improved the performance, power, and life span of lithium-ion over time. But lithium-ion batteries cannot last forever. Lithium-ion batteries can cycle up to 4,000 times and reach 80% discharge depth (DOD) at this time. So now, lithium ions batteries have better performance than others in the market, so they are used in most electronic devices, vehicles, and electric grids.
But for these batteries the process of charging and discharging making them go bad as time passes. So, it is recommended that batteries be changed if they can only hold up to 70% to 80% of their original capacity.In other words, their DOD went from 100% to 70% to 80%. But if the lithium-ion battery is kept with proper maintenance and care of, it may last up to 7 years with full efficiencyif it is charged and discharged on average once a day. And the future can be predicted to have a lithium-ion battery that can last forever. Still, it's not possible because the battery will either age or fade, reducing capacity or power.
4. Which lithium battery lasts longest?
Lithium iron phosphate battery is long lasting battery that tend to last up to 4000 cycles or more and can work under -20 to 60 degrees. And lithium iron phosphate batteries are light weighted and about 23% lighter than other batteries, such as alkaline batteries. Lithium-ion batteries are tended to last longer than alkaline batteries or any other batteries out there as they use ions to store and supply power to the devices. These ions move back and forth between two battery poles with no additional chemicals being used. Other batteries use lead-acid chemicals that make their batteries heavier and having a short life span than lithium-ion batteries.
5. Why do batteries not last long?
Lithium-ion battery is no doubt long lasting battery. But it cannot last forever because ions have to move back and forth between positive and negative terminals of the battery to produce power inside the battery. In theory, ions can move back and forth infinitely to create ultimate power without power or efficiency fading over time, making it long lasting battery. However, any side reaction that can produce or consume lithium ions or electrons can lead to a change in the battery capacity balance, which, once the battery capacity balance state changes, is irreversible and can be accumulated through multiple cycles, having a serious impact on the battery performance.In lithium ion batteries, in addition to the redox reaction when lithium ion deembedding, there are also a large number of side reactions, such as electrolyte decomposition, active substance dissolution, lithium metal deposition, etc.
6. How do you make batteries last longer?
To make batteries last longer, we should avoid overcharging them and over discharging them. Overcharging or overusing will result in losing the power and efficiency of the battery by constantly being charged and discharged. In general, keeping your phone at 30-80% of your battery power makes the battery more durable. Batteries should be charged at 20% or below, but it doesn't have to wait for less than 20 percent to charge. The lithium-ion battery is suitable for a small amount of charging multiple times, keeping the battery healthy for a long time than a quick charge. This charging method can also increase the number of battery cycles. And batteries should be removed at 80% or, best of all, at 100% and should be removed as soon as it is charged. Keeping the battery full or high for a long time will accelerate the aging of the battery and make the battery less durable.
Therefore, the charger should be unplugged in time after the phone is fully charged to avoid a high battery state of charge for a long time to prolong the battery life. Charging overnight can have a harmful impact on the battery as the regular sleeping hours are between 6 to 8 hours while most standard batteries are charged within 2 to 3 hours which will be overcharging of the battery. And while charging, always use the original charger or a charger that provides the same power required for charging the batteries. To make it be long lasting battery, the battery or device should not be used during the charging and remain idle until charging is complete. Because it will have a harmful effect on the battery lifespan and device, tend to draw power directly from the power plug, which will result in short battery life and reduce its efficiency as required charging power is reduced.
