Bad Wireless Charging? — High Energy Density Lithium Iron Phosphate Lifepo4 Cell

From:CTECHI GROUP Limited     Release time:2019-01-12

Overview:Because many people still don't know much about Qi, they are also worried about whether wireless charging will shorten the battery life of smartphones. Indeed, this is a question that deserves our attention, although the answer to this question is not very clear.

Because many people still don't know much about Qi, they are also worried about whether wireless charging will shorten the battery life of smartphones. Indeed, this is a question that deserves our attention, although the answer to this question is not very clear.


However, according to experts, it is not good to keep the mobile phone in a full state for a long time. According to experts, although we all know that we can't overcharge the cell phone's battery, keeping it at its maximum will also lead to a rapid reduction in cell phone battery power.


But science also needs a better explanation: the working principle of mobile phone batteries, namely lithium-ion batteries. Lithium-ion batteries charge and discharge through the movement of lithium ions between positive and negative electrodes. The positive electrode releases lithium ions which migrate to the negative electrode and stores them as energy. When the battery discharges, the ions move back to the positive electrode and generate electricity. The electrolyte used as a medium for lithium ion reciprocating motion decreases with time or is used in this case.


At the same time, the more batteries are charged, the faster the electrolytes degrade, regardless of whether they are charged wirelessly or wirelessly. So wireless charging does not shorten battery life. Overcharging does.

Wireless charging VS wired charging, which is better?


Some people believe that wireless charging will accelerate the rapid decline of cell phone power because the induction coil used in wireless charging will use lithium-ion batteries to keep the cell phone on the charging pad, while wired charging is cable.


However, experts in the industry have given reasons to disagree. Although battery life usually decreases with the increase of charging cycles, when the battery capacity is maintained at about 50%, the battery life will increase four times.


In other words, if you don't let cell phone batteries burn under 50% or run out all day, their battery life may last longer. So what is the basis for judgment?


However, everything has many aspects. In this case, both support wireless charging and oppose wireless charging, but the fact may be somewhere in between.


The battery design of wireless charged mobile phones is designed to maintain 80% of the original capacity within 500 full charging cycles, which is enough for the vast majority of people who change their phones within two to three years. But how long it takes depends on charging habits, although two to three years may be enough for the speed of buying a new phone.


Whether or not you use wireless charging technology to power batteries, as Qi charging power continues to rise, more and more people begin to accept and use wireless charging. Whether mobile phone batteries will be affected by this, users may already have an answer in their hearts.
