Japan plans to develop solid-state batteries experiment on the moon

Want to use solid-state batteries in space, it doesn't sound like anything new. But the problem is that on earth, this technology has yet to popularity. Still, there are many start-ups, hope as soon as possible to carry out the battery experiments on the moon. Is positive because it saw the bright future lunar exploration prospects. The private or state-owned institutions, such as Essex and experimental apparatus are racing to the robot to the moon. But after arrived at the satellite, need to be considered for a long time without sun backup energy solution.

the sun and not the sun, the moon will experience the extreme difference in temperature. Want to find a enough to bear the temperature fluctuations, but still effective energy storage batteries, is of great significance to explore the moon.

solid-state batteries, may be a promising solution. Compared with batteries, it adopted the solid electrolyte, you can take it easy as traditional super version of the lithium ion battery.

in order to help the charged particles from between the poles of mobile batteries, lithium ion need to rely on a flammable liquids as an electrolyte. Unfortunately, even in the earth, the liquid can also cause some problems.

under the high temperature, the electrolyte could lead to battery failure, even for mobile devices such as explosion fire. In low temperature environment, will be frozen solid electrolyte, lead to sharp attenuation in the battery.

learn from ningxia province development and reform commission website: on December 18, ningxia province development and reform commission issued 'about 50 mw2017 in photovoltaic base indicators adjust the opinions of the public, to be delivered to the outside, will in ningxia tianyuan photovoltaic power generation co. , LTD. , apply to the by commission took the initiative to give up 50000 kw in 2017 of the construction of the photovoltaic (pv) outside the base index, adjust to the actual complete investment larger helan fishponds love friends, new energy photovoltaic power generation demonstration project ( Size is 30000 kw, the construction unit to yinchuan love friend grace energy electric co. , LTD. ) Dry, ningxia achieves distributed fishing light complementary agricultural project ( Size is 1. In 90000 kw, the construction unit for county in new energy development co. , LTD. ) , avoid the waste of investment, reducing the loss of enterprises.

as a comparison, solid electrolyte in the battery, after a particularly elaborate design. Although there is no use liquid to package, the solid material can still help ion moves back and forth.

the Swiss federal solid-state batteries of materials science and technology laboratory researcher, Francesco Pagani said:

no fluid to package all solid-state batteries, but different parts of the stack into solid layer, and can let the battery become more compact compared with the traditional lithium-ion batteries, solid-state batteries can save more energy, charging speed is faster.

in theory, it is better able to withstand the severe temperature difference, from the sun 260 ℉ ( 127℃） And to the shadow - 280℉（ - 173℃） 。 Even if overheating, will not burn easily or explosion.

, though in extreme low temperature solid-state batteries charging speed will be slow, but at least it can survive in space environment. If for lithium ion battery, there is no necessary to consider.

it is understood that the moon in the planning of solid-state batteries, will be made by the Japanese NGK Spark plug-in. Did not determine the exact specifications of the solid-state batteries, but its electrolyte will use ceramic material (known Characteristic is quite stable, so very popular) 。

the current plans to do some very basic test, to verify that the battery can survive in the vacuum environment and keep the charge, the hope that the feasibility of this experiment can extend the space of batteries.
