Solving the Ultimate Problem of Lithium Battery-Research on Ceramic Circuit Board

Lithium batteries are divided into lithium metal batteries and lithium ion batteries. Lithium metal batteries are relatively new concepts. Today we are going to talk about lithium ion batteries. Lithium ion batteries do not contain metallic lithium. Now we can use such a small mobile phone and portable electronic equipment to drive electric cars for long distances, which can not be separated from lithium-ion batteries. In 1992, with the advent of lithium-ion batteries, people's eldest brother gradually disappeared. Although it has a lot to do with integrated circuits, but without lithium-ion batteries, mobile phones now have at least a large size. Several times.

Lithium-ion batteries are extremely sensitive to temperature, too low temperature lithium-ion batteries can not work, too high temperature, think of the tragedy of Samsung you know. Charging and discharging of lithium-ion batteries is a chemical reaction process. Under a calm surface, lithium ions run back and forth between positive and negative electrodes. When a lithium-ion battery is charged, the lithium atom of the positive electrode loses electrons and oxidizes to lithium ion. Lithium ion enters the negative electrode through the electrolyte and gets an electron, which is reduced to lithium atom. When discharging, the process is opposite. In addition, in order to prevent the direct contact between the positive and negative electrodes and short circuit, the battery uses a thin-hole diaphragm to isolate the positive and negative electrodes.

The problems of gas expansion, high temperature and explosion of lithium batteries are usually related to overcharge, overdischarge and high current, which will cause damage to the batteries. These three problems are very common. Ultra-low temperature environment is rare, but for Ultra-high temperature, it's not easy for more and more power appliances nowadays. So how to get a steady current and how to derive heat is crucial. Then we have to talk about our ceramic circuit boards.

Ceramic circuit boards are currently the highest thermal conductivity circuit boards on the market, so I believe you will understand, what does high thermal conductivity of ceramic circuit boards represent, representing the ability to timely derive all the heat emitted by lithium-ion batteries, so how can we solve the problem of high current? In addition to the circuit control system, it also has a great relationship with the circuit board. The higher the precision of the circuit board, the more uniform the circuit, which means that the current flow will be more stable. At present, only one of the domestic ceramic circuit manufacturers can achieve this technology, so that the perfect combination of ceramic and circuit ionic state, to achieve absolute uniformity, for the stability of the current has great benefits.

Last December, Huawei took the lead in introducing graphene lithium-ion batteries. The role of graphene in these batteries is pure heat conduction. However, graphene has not been commercialized yet. There is still a long way to go for graphene commercialization. What users are most concerned about is when to realize commercialization and when commercialized technology can benefit users and promote the development of lithium battery industry. 。 Ceramic circuit boards as a very mature product, after all, are still the current king.

Ceramic circuit boards are ultimately able to stand at the top of the market, technology replacement can not make ceramic circuit boards feel threatened, but is an endless power, after all, ceramic circuit boards also have a long way to go, but also can carry out nearly unlimited update iterations. And all we have to do is make good use of it.

Whether the future is ceramic circuit boards or graphene, it is not our scope of consideration. We just need to know which one can better meet the demand. The life and death of products are determined by the market. Ceramic circuit boards are not only a market direction for lithium-ion batteries, but also include LED,special and so on. They are the most promising ones at present or in the next century. In some industries, it can be predicted that ceramic circuit boards will leave a strong mark on the stage of the history of the electronic industry.
