The first "breathing battery" came out: one can run 1000 km

First talk about the Fudan University aqueous lithium battery

The first "breathing batteries" come out, you can release oxygen, one can run 1000 km!

Nature published a massive study by Fudan University in China, an aqueous lithium battery. The battery has an energy density of greater than 220 Wh / Kg and an energy efficiency of up to 95%, allowing electric vehicles to travel up to 400 kilometers.

【This is the focus of new energy air battery】

Honda claimed to have developed the world's first commercially available air-to-air cell, this time using magnesium because it costs 96% less than lithium and the use of magnesium batteries will significantly reduce its production costs.

Parameters: The capacity of the air battery is about 3000Wh / kg, which is about 8 times that of the existing lithium-ion battery. The efficiency of charging and discharging for the first time is as high as 93%.

The research team gave it a very interesting name, air battery, because it releases oxygen when it powers the device. Japan also uses it as a backup energy for earthquakes!

However, this type of battery has its own drawbacks. The current density is very low, which is about 1/50 to 1/20 that is required by a car. It still has a long way to go before it enters the market.

【China is also competing, research crowdfunding】

At present, domestic research institutes put such batteries on the market ahead of time, and used in outdoor camping emergency lighting. The led lamp is very suitable for outdoor, only need water can light, 30 grams but it is an energy giant, when about 80 hours.

On the new energy, many companies in the recent layout, such as Apple's all-solid state lithium-ion battery patent applications, Tesla applied for the patent of metal-air batteries, in the future, there will be a fierce energy patent war!

GL Steel Coil

GL steel coil is an important alloy material often used in daily life. The galvalume steel coil is composed of aluminum-zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at a high temperature of 600℃. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense four-element An alloy of crystals.
Characteristics: Aluminium galvanized steel coil has many excellent characteristics: strong corrosion resistance, 3 times that of pure Galvanized Coil; beautiful spangles on the surface, which can be used as building exterior panels.
1. Corrosion resistance:
The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, which prevents corrosion-resistant substances from further corroding the interior.
2. Heat resistance:
aluminum-zinc alloy steel coil has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius. It is similar to the high temperature oxidation resistance of aluminum-plated steel sheets. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
3. Heat reflectivity:
The heat reflectivity of Galvanized Steel Coil is very high, which is twice that of galvanized steel. People often use it as a material for heat insulation.
4. Economy:
Because the density of 55%AL-Zn is lower than that of Zn, the area of galvanized steel coil is more than 3% larger than that of coated steel coil with the same weight and the same thickness of gold plating.
use
Construction: roofs, walls, garages, soundproof walls, pipes and modular houses, etc. Automobiles: mufflers, exhaust pipes, wiper accessories, fuel tanks, truck boxes and other home appliances: refrigerator back panels, gas stoves, air conditioners, electronic microwave ovens, LCDs Frames, CRT explosion-proof belts, LED backlights, electrical cabinets and other agricultural applications: pig houses, chicken houses, granaries, greenhouse pipes, etc. Others: thermal insulation covers, heat exchangers, dryers, water heaters, etc.
Precautions for use
Storage: It should be kept indoors such as warehouses, kept dry and ventilated, and do not store it in acidic climates for a long time. When storing outdoors, it is necessary to prevent rain, and avoid condensation caused by oxidation stains. Transportation: To avoid external impact, SKID must be used to support steel coils on transportation tools to reduce stacking and take rain-proof measures. Processing: The same lubricating oil as the aluminum plate is required for the cutting process of COILCENTER. When drilling or cutting galvanized steel sheets, the scattered iron filings must be removed in time.
Commonly used post-treatment of galvanized steel coil
DRY dry OIL oiling Chromate chromate passivation AFP/Galva clean resistant to fingerprints Non-Gr, Gr-free, cadmium-free and fingerprint resistant
