At present, most smart phones use lithium ion battery, so what are the specific advantages of lithium battery, will make all mobile phone brands, even the iPhone, lithium battery as the first choice of mobile phone battery life?

 

 

 

01. What is a lithium ion battery

 

 

 

Lithium battery system is divided into lithium battery and lithium ion battery. Today's mobile phones and laptops are powered by lithium-ion batteries, commonly known as "lithium batteries", which represent modern high-performance batteries. But the real lithium battery is extremely dangerous, rarely used in daily digital electronic products.

 

 

 

Lithium ion battery is also called secondary battery (rechargeable batteries), rechargeable lithium ion batteries in the most widely used in modern digital electronic products, it has to do with the biggest difference is that the latter lithium-ion batteries using lithium metal as the anode, and lithium ion battery is a lithium elements (graphite) and petroleum coke as electrode materials, to a great extent restrained the lithium highly active, solves the security problems of the traditional lithium-ion batteries.

 

 

 

02. Advantages of lithium-ion batteries

 

 

 

Since lithium-ion batteries are now the smartphone of choice, they have their advantages. Lithium-ion batteries are faster to charge and last longer than conventional battery technologies, with a higher power density allowing for longer battery life and a lighter body.

 

 

 

Lithium ion batteries, compared to mobile phones, the most important thing is actually two: good safety performance, long cycle life.

 

 

 

Tips1. Good safety performance

 

 

 

Pollution-free. Lithium ion batteries, different from traditional lithium batteries, are highly active and prone to short-circuit explosion. Lithium ion batteries are designed with many protection mechanisms and are safer. No memory effect. The memory effect here refers to some batteries will remember the user's charge, discharge range and mode, after a long time, it is difficult to change this mode, also can not do a large amount of charge and discharge, and lithium ion batteries will not have memory effect. This is why lithium-ion phones can be charged on demand.

 

 

 

Long cycle life

 

 

 

Lithium-ion batteries generally have a service life of 2-3 years. Generally, it can reach more than 500 times, even more than 1000 times, and lithium iron phosphate can reach more than 2000 times. For mobile phones, long cycle life means longer use time. For some high-quality batteries, such as the lithium battery of iPhone, the battery can still maintain 80% capacity after 500 charging cycles.

 

 

 

So far, lithium battery is the best choice for mobile phones. However, with the development of graphene super battery, we believe it will soon be put into the field of mobile phones. It only takes a few minutes to fill up the phone. Like me, pay attention to the gold point, get more science knowledge, welcome to comment on the comments to say your opinion.
