The silicon battery that can be used in mobile phones is developed: refuse to explode and mass production

Lithium batteries are the bottleneck of many smart terminal breakthroughs, and many companies and research institutions are also actively preparing for more advanced battery technology.

According to foreign media reports, a startup called XNRGI hopes to break this situation and plans to mass-produce "porous" silicon batteries next year. It has better energy density and lower manufacturing costs than traditional lithium-ion batteries, and uses It is also safer.

XNRGI has been developing for 15 years, its energy density is four times that of lithium ion batteries, and the cost is only half of it, and their "porous" silicon batteries can be used in many scenarios, such as smart phones and many other smart terminals .

In addition, XNRGI uses a method similar to that used by semiconductor companies to build processors to make cells from wafers. After etching very dense 20 × 20 micron honeycomb patterns into these wafers, they coat them with lithium and other metals to form the anodes and cathodes of so-called “microbatteries”, accommodating 36 million silicon wafers per 12 inches These vertical micro-batteries (energy density exceeds 400Wh / kg) form a macro battery, which has the advantage of faster charging due to its unorthodox architecture.

XNRGI batteries are recyclable and are not as susceptible to thermal runaway as traditional lithium-ion batteries. Their energy density exceeds 400Wh / kg, making their manufacturing costs lower, so they are ideal for electric vehicles and grid storage.
