Battery technology from the perspective of battery safety -Lithium - Ion Battery Equipment

At present, the structure of lithium ion battery is divided into positive stage, electrolyte and negative pole. There will be a layer of diaphragm between the electrolyte and the positive and negative electrodes. The root cause of Samsung's problem battery is this diaphragm. The unqualified diaphragm may cause direct contact between the positive and negative electrodes, which is equivalent to a short circuit, and then it may self ignite, and the serious point is explosion!

In fact, the lithium-ion battery technology used in hand is still decades ago, and there has been no substantial breakthrough in battery technology for a long time. Some are just some optimizations in the production process and packaging process, which makes the mobile phone's endurance a major pain point affecting the user experience, and sometimes there are security risks. Is there no new battery technology for so long? Next, the author will talk about the new battery technology that is expected to be applied to mobile phones in recent years.(Lithium - Ion Battery Equipment)

Supercapacitor battery

In fact, capacitor is not a new thing, it can be said to be an "antique", while super capacitor battery is a super capacitor, which can be quickly charged, store a lot of power, and then discharge at a reasonable speed. This kind of "battery" is not easy to damage, and can conduct tens of thousands of charging and discharging cycles.

Graphene based lithium ion battery

In recent years, graphene has always been a popular word. Graphite was born in 2004. It is not only the thinnest material, but also the strongest material. The breaking strength is 200 times higher than the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is the thinnest and strongest material in nature at present, and has many excellent physical and chemical properties.


The graphene based lithium ion battery has excellent performance. It can work in an environment of - 30 ℃ to 80 ℃. Its cycle life is up to 3500 times, and its charging efficiency is 24 times that of ordinary charging products. The working principle of this kind of battery is to make use of the characteristics that lithium ions can shuttle rapidly between the graphene surface and the electrode.

As a matter of fact, the performance of mobile phones has already been seriously oversupplied. The 2.5GHz 8-core CPU and 6GBRAM cannot be fully utilized. Compared with the evolution of mobile phone performance, the mobile phone battery is basically stagnant. Manufacturers should not always pursue performance, but ignore the feeling of the battery.
