Li ion mobile phone battery
Currently the vast majority of smart phones use lithium-ion batteries, so what are the specific advantages of lithium batteries, will make all cell phone brands and even the iPhone, lithium batteries as the first choice for cell phone battery life?
01. What is lithium-ion battery
Lithium batteries are divided into lithium batteries and lithium-ion batteries. Nowadays, cell phones and laptops use lithium-ion batteries, which are commonly known as “lithium batteries” and represent modern high-performance batteries. True lithium batteries are extremely dangerous and are rarely used in everyday digital electronics.
Lithium-ion batteries, also known as secondary batteries (rechargeable batteries), rechargeable lithium-ion batteries in modern digital electronic products in the most widely used, the biggest difference between it and lithium batteries is that the latter uses lithium metal as a negative electrode, while lithium-ion batteries are lithium-containing materials (graphite and petroleum coke) for the electrode, to a large extent, to restrain the lithium’s high activity, to solve the traditional lithium batteries exist in the safety issues.
02. Advantages of lithium-ion batteries
Since lithium-ion batteries are now the preferred choice for smartphones, they naturally have their advantages. Compared with traditional battery technology, lithium-ion batteries charge faster and last longer, and the higher power density enables longer battery life, while the body is also lighter.
The most important thing about lithium-ion batteries for cell phones is two things: good safety and long cycle life.
Tips1.
Harmless. Lithium-ion batteries, unlike traditional lithium batteries, high activity is very easy to produce short-circuit explosion accidents, lithium-ion batteries in the design of a lot of additional protection mechanisms, but also more secure. No memory effect. Here the memory effect refers to some batteries will remember the user’s charging and discharging amplitude and mode, after a long time it is difficult to change this mode, and can not do a large amount of charging and discharging, and lithium-ion batteries do not have the memory effect. This is also the reason why lithium-ion cell phones can be charged on demand.
Tips2. Long cycle life
The service life of lithium-ion batteries is generally 2-3 years. Generally can reach more than 500 times, or even more than 1,000 times, lithium iron phosphate can reach more than 2,000 times. For cell phones, long cycle life means longer use, for some high-quality batteries such as iPhone lithium batteries, after 500 charging cycles, the battery can still maintain 80% of the capacity.
The above is today’s science knowledge about lithium batteries, cell phone choice of lithium batteries, is by far the best choice, but with the development of graphene super battery, I believe that it will also soon be put into the field of cell phones, cell phones are full of just a few minutes of things, small gold point is also very much looking forward to the arrival of this day. Like me, pay attention to the gold point, get more science knowledge, welcome to leave a message in the comment section to say your insights.
