Breakthrough solid state battery technology! Xiaomi Announces New Battery Technology

As the most famous technology company in China, Xiaomi's various smart devices have been welcomed by many users, and it has launched many new technologies. Recently, Xiaomi announced a new battery technology, which can be said to be more powerful than the most famous high-tech company Tesla/BYD in the world. Come and see the specific information of Xiaomi's battery technology!

Break through solid state battery technology! Xiaomi Announces New Battery Technology 

Recently, Xiaomi announced the solid-state battery technology, with its energy density exceeding 1000Wh/L. If the solid-state battery is used, Xiaomi 13 can hold 6000mAh in a volume of 4500mAh.

Compared with the current lithium metal solid state battery developed in Japan, the energy density is as high as 417Wh/kg and 935Wh/L, so the energy density of millet 1000Wh/L is about 446Wh/kg.

So what level is this?

Tesla Model 3 (imported version) is 300Wh/kg, Porsche Taycan is 270Wh/kg, MoldX is 186.2W/kg, Tesla Model 3 is 168Wh/kg, BYD EV is 150Wh/kg, and Wuling Hongguang MINI EV is 130Wh/kg.

The average energy density of the battery on the market is 160Wh/kg, while the energy density of the solid-state battery is two to three times that, which means that the endurance of the electric vehicle can easily exceed 1000 kilometers. How does this technology work? The author will systematically introduce the content of solid-state battery.

All-solid battery is a kind of lithium-ion battery. Solid electrolyte is used in the channel of lithium ion moving back and forth to replace the electrolyte of existing battery. The electrolyte of the existing battery is made of organic solvent materials, which may cause fire and has problems in safety. The safety of the power battery is closely related to the liquid electrolyte. The solid electrolyte used in the solid battery has the characteristics of good insulation, non-flammable and non-volatile, which can significantly improve the safety.

The all-solid-state battery does not use flammable electrolyte, which is more safe. The all-solid-state battery does not need parts called isolation layer, which can reduce the number of parts and reduce the manufacturing cost.

In addition, solid-state batteries have a wider range of applicable temperatures and longer cycle life. Last September, the Harvard University team developed a new type of solid-state lithium metal battery. In the laboratory, the battery prototype of the team can cycle more than 10000 times in its life cycle, which is several times more than the cycle times of ordinary liquid battery.

Energy density, charge-discharge ratio performance, cost, safety and cycle life are all key indicators of the battery. Generally, a major breakthrough in one or several indicators can be achieved at a certain stage, but it is very difficult to achieve mass production only when all indicators are met at the same time. In addition, the conductivity, preparation technology, industrial chain support and manufacturing cost of solid state batteries are all difficulties. It is estimated that they are more than 4 times of that of ordinary lithium-ion batteries.

In general, this new solid state battery technology of Xiaomi is quite good. In addition to other technological breakthroughs, we believe that Xiaomi will bring more interesting and high-tech smart devices to you in the future. You can look forward to it!
