China3D printingNet, September 23, we usually find that the newly bought toy children have not had enough fun before they have no electricity, and most of the batteries are very short-lived and expensive.So glad we know that many researchers are investing time and resources to determine how to proceed3D printingBattery. Although the battery is not something you can quickly print out on a normal desktop system. but,3D printingThe battery has other advantages.

The Swiss holding company Blackstone Resources AG focuses onMetalThe battery market, and has been investing in next-generation battery technology through its German subsidiary Blackstone Technology GmbH.The company just announced that it uses proprietary3D printingTechnical efforts to manufacture lithium-ion solid-state batteries have reached the point of practicality.
Blackstone Resources AG firmly believes that it can produce reliable lithium-ion batteries with higher energy density levels in large quantities and at low cost. The goal is to keep costs well below 80 Euros per kWh. This will represent the ultimate breakthrough in storage technology.According to China3D printingNetwork understanding,
Traditional battery designs use liquid or polymer gel electrolytes, while solid-state batteries use solid electrodes and solid electrolytes. They do not require the use of flammable liquid electrolytes, so they are safer to use, but cost a lot of money.
Blackstone Resources AGSaid that compared with traditional manufacturing methods, using its patented3D printingThe process of manufacturing batteries has many advantages, for example, more charging times, lower cost, in addition to an increase in energy density by more than 20%, and a higher output flexibility in terms of cell format.

“Blackstone has developed a patented3D printingBattery technology, due to its advanced processing technology, its energy density is 25% higher than that of traditional lithium-ion batteries. Except for thicker layers, almost all geometric figures can be printed. Multi-layer batteries are also possible, which can provide higher voltages at the battery cell level.
3D printingBattery technology is the key to mass production of solid-state batteries (SSB). By developing solid-state battery printing technology, Blackstone will be able to double the energy density of the batteries it produces at a lower cost. Moreover, in the process, it will be able to provide it with its own battery metal. “
In addition, by adopting3D printingManufacturing batteries can reduce the amount of materials that do not store any energy (such as aluminum and copper) by up to 10%.
The company is now moving to new heights and plans to produce3D printingThe solid-state battery has actually created and tested its first batch of SSB battery prototypes.Now, it is working to further develop its technology in order to be able to3D printingSSBBatteryCarry out mass production.

Holger Gritzka, CEO of Blackstone Technology GmbH, said: “Plus, we have been3D printingThe development of battery technology, this development paved the way for the mass production of solid-state batteries.In addition to major markets such as the automotive industry, marine applications and new 5G wireless networks will also benefit from3D printingThe advantages provided by solid-state batteries. “

By using automatic3D printingManufacturing SSB lithium ion batteries,BlackstoneThe group can save 70% of the CAPEX (Capital Expenditure of Recorded Goods or Services) normally used to produce them. The company stated that it “may change the rules of the game” for the production of SSB and showed that it can create battery cases, composite materials And solid-state electrolyte, which is necessary for mass production of solid-state lithium-ion batteries.
