British company Oxis Energy said that its high-capacity lithium-sulfur battery can hold five times the energy per pound of lithium-ion batteries, and is expected to significantly increase the range of electric aircraft. The world is looking for a true source of energy for electric aviation, but so far, the existing lithium-ion batteries are so heavy that short trips are not economical.
For electric aviation, the energy density of the battery is the key, and the leading commercial lithium-ion battery can still only store about 250Wh / kg (that is, the Tesla 2170 battery used in Tesla Model 3), which is higher A new type of chemical battery with density while still being reliable and safe is the dream product of the next generation of aviation industry.
In this case, looking backwards may be an option: lithium-sulfur batteries have been around since the 1960s and have long been known for their relatively high energy density and low cost, but their disappointment Is the cycle life. Lithium polysulfide is very soluble in the electrolyte used in the battery, which means that the cathode will eventually melt over time.
Oxis said that it has developed a safe and non-flammable electrolyte that can store lithium metal for a longer period of time, while providing an energy density of more than 500Wh / kg, which can still be proved in the case of puncture and perforation. It is safe and has a life span of about 250 charging cycles. The company believes that the life cycle can be extended to 500 cycles in the next few years of technological development, which is the life of many lithium-ion batteries.
Oxis has reached a cooperation agreement with Bye Aerospace, a company specializing in electric and solar aircraft in Colorado, to increase the flight time of future aircraft by 50% to 100%. If it goes well, this battery is likely to arouse the interest of large aircraft companies.
Oxis is preparing to build manufacturing plants in Brazil and Wales, and hopes that its batteries will match electric buses in Brazil's busy public transportation.
The Cnc Cutting Machine has the characteristics of fast cutting speed and small slit in the cutting process, which may lead to limited actual cutting speed, excessive kerf and uneven cutting surface, and eliminate the mechanical failure of the plasma CNC Cutting Machine. Failure to properly set the plasma CNC cutter related parameters during operation will also affect the actual cutting effect.
The hub processing parts of large ships are concentrated in the base of high-power diesel engine, frame, cylinder block, cylinder head, piston rod, crosshead, connecting rod, crankshaft, and gearbox drive shaft, rudder shaft and propeller, etc. The material is special alloy steel, which is generally processed in small batches and requires a processing yield of 100%. The hinged parts have the characteristics of large weight, complicated shape, high precision and large processing difficulty. Large-scale ship pivot processing requires high-power, high-reliability and multi-axis heavy-duty, ultra-heavy CNC cutting machines.
