Technology is making great changes to individuals and society. Scientists are using green energy technology to paint a picture of human beings. The inexhaustible world of energy can not be realized in the short term, but it is certain. Yes, many of the human illusions have been realized by technology. In the automotive field, the various green energy technologies generated by environmental pressures are also controversial and controversial. But we should believe that there will always be a green energy technology that can subvert the traditional fuel vehicles and carry the mission of improving the human environment:

A graphene battery combined with a super capacitor
Researchers at the National Graphene Institute at the University of Manchester in the United States have used graphene as an additive to explore new ways to reduce battery size and weight and extend battery life.
According to Professor Forsyth, the combination of graphene batteries and supercapacitors can provide a powerful driving force for the sales of electric vehicles. At present, these eco-friendly cars use batteries weighing up to 200 kilograms, which is almost the weight of three passengers. By reducing the weight of the battery, graphene will help improve the energy efficiency of the car, and increase the endurance of the electric car to exceed the current limit of about 100 kilometers.
Professor Forsyth stressed that if we can extend the endurance of electric vehicles between two charging stations, we should immediately make electric vehicles popular. But how can the battery break through the driving restrictions of real life? Electric cars are not as smooth as all other cars. As the driver accelerates, the peak demand for power will put pressure on the battery and may limit its useful life.
To test whether the prototypes that incorporate graphene batteries and supercapacitors are capable of meeting this job requirement, Professor Forsyth exposes it to real-world pressure by simulating different driving situations. He said that we can even test driving skills in extreme weather conditions. Many batteries are difficult to function in cold weather conditions, and any weakness can be found through our climate chamber.
Of course, graphene-based storage is not limited to transmission. As the UK becomes more dependent on renewable energy, it will also play an important role in the future of the national grid. Professor Forsyth questioned, if we only rely on solar energy and wind energy to generate energy, what happens when there is a cloud and a breeze one day? If we can develop a high-capacity energy storage mechanism, the industry will be able to store electricity first. Need.
2. Bosch's new battery will double the mileage of electric vehicles
Bernd Bohr, the former head of automotive business at Bosch, has said that the company will improve the energy density of lithium-ion batteries in two steps. In 2016, the energy density of the battery unit will increase from the current 130 watt hour to 200 watt hours; in 2020, the energy density of the battery unit will be further increased to 300 watt hours, thereby doubling the electric vehicle stroke.
3. The United States Institute of Technology (MIT) designed a new battery or will increase the cruising range
Scientists at the Massachusetts Institute of Technology (MIT) are currently developing new battery technologies that they say will significantly reduce the size of electric vehicle battery systems and potentially double the mileage of electric vehicles.
Most standard battery systems are made up of a large number of materials, most of which provide structural support rather than energy supply. Researchers say the newly developed technology will involve most of the materials in the energy supply. The team's head, Yet-MingChiang, said that the new technology developed batteries will be 10 times more energy than traditional designs.
This technique uses a semi-solid flow battery system in which the particles are suspended in a liquid electrolyte called "CambridgeCrude". Two fluid-like fluid mixtures—a positively charged, one negatively charged—inject through the system, allowing lithium ions to shuttle freely through the diaphragm, producing electricity.
Four. Fudan new lithium battery can charge 800 miles in 10 seconds
A new type of water lithium battery developed by Fudan University, can take up to 400 kilometers of new energy electric vehicles as long as it takes 60 seconds to charge 60 degrees.
The research results released by Fudan on June 8 were recently published in the journal Science Report (Sci.Report). The scientific research results are expected to solve the major obstacles in the current global electric vehicle industry and inject new impetus into the development of new energy.
V. ECOmove uses biomethanol to increase its battery life
The new electric vehicle chassis has six battery modules instead of a fixed battery.
The new wheeled electric vehicle has a top speed of 75 mph.
The car may be greener. The low cost of electric vehicles than its rival gasoline-powered vehicles has been its main drawback. The electric vehicle industry has been working hard to improve this deficiency, which is the main reason why buyers do not buy electric vehicles.
The advent of a new electric car may change this state, and the car will be able to reach 500 miles (800 kilometers) after a full charge.
Cruising range: QBEAK promises a mileage of 500 miles (800 km) after a full charge.
The modular design concept car (MECc), developed by three Danish companies, uses biomethanol to increase its battery life.
The CEO of ECOmove, the new QBEAK car designer, says that biomethanol produces significantly less carbon dioxide than diesel or gasoline.
He told Cable News reporter that with our advanced manufacturing technology, the car can be made truly lightweight, weighing only 425 kilograms and cruising range of up to 500 miles (800 kilometers).
The fuel cell uses biomethanol/water to generate electricity, and the waste heat generated during power generation can power the car's heating and cooling system.
An important royal figure will become a potential buyer: Prince Charles of England visited the ECOmove electric concept car during his visit to Denmark earlier this year.
Strong interest: When Prince Charles and his wife Camilla visited the Vitus Bering Innovation Park, the staff introduced them to the superior performance of the new electric car.
This innovative chassis design truly advances technology.
6. Aluminum air battery makes the electric car last for 3,000 kilometers and only needs to add water
Can an electric car run for 19 hours in a row, from Toronto to Halifax 1800 km away, without parking for charging? This will theoretically be feasible. Recently, Alcoa Canada and Israel's Phinergy have demonstrated such a battery technology with super endurance to the public in Montreal.
The biggest obstacle to the difficulty of popularizing electric vehicles driven by lithium-ion batteries is the limited mileage. The current endurance is mostly between 135 km (Nissan Leaf) and 480 km (Tesla S-type), unless a large number of fast charging stations are installed. Otherwise, it is not suitable for driving an electric car for long distance travel. Alcoa Canada and Israeli company Phinergy's new 100 kg aluminum air battery stores enough electricity to drive 3,000 kilometers. In contrast, the Tesla ModelS has a battery of more than 500 kilograms and a mileage of less than 500 kilometers.
The new battery is not charged from the general grid, but is charged in the melting plant of Alcoa's hydroelectric power station. The fully charged battery is actually a heavy panel made mostly of aluminum. The aluminum plate uses the oxygen absorbed from the air and the water that the user adds to the car to chemically convert the aluminum into alumina, thereby releasing energy and continuously powering the car. The oxidation of aluminum occurs naturally when aluminum is exposed to the air. The surface of the alumina prevents the deep aluminum from continuing to react. The new technology used in the new battery contains an electrolyte that dissolves the surface oxide layer and allows the reaction to continue.
According to Alcoa Canada, cars that use this type of battery still need to keep lithium-ion batteries. The aluminum batteries only start when the lithium battery is exhausted, so it can be used for a long time, and only need to fill the water every month. Usually, after reaching the end of use in a year or so, you can replace the fully charged aluminum battery at the service station.
Using this prototype with an additional battery, it was tested on the Formula 1 circuit in Montreal last week. Phinergy also introduced the new invention at the International Aluminum Conference in Canada on June 4. At present, the inventors are negotiating production agreements with Quebec to try to get this zero-emission vehicle into trial operation as soon as possible.
Seven. Argonne laboratory battery technology can make electric vehicles a single charge cruising range of 1000 miles (about 1609 km)
The Argonne National Laboratory (ANL) is one of the oldest and largest scientific and engineering research laboratories of the US government—the largest in the Midwestern United States. ANL was the first national laboratory in the United States that was chartered in 1946 and is one of the largest research centers of the US Department of Energy. Argonne's science and engineers are developing new advanced batteries and fuel cells, as well as advanced power generation and storage systems to ensure the future of the US energy.
Carlo Segre, a professor of physics at the Illinois Institute of Technology, said that the power battery technology researched with Argonne Laboratories is expected to increase the cruising range of electric vehicles to 500-1000 miles. The new technology will be based on liquid batteries developed by nanomaterials, which charge faster than conventional batteries and do not emit carbon dioxide.
At the same time, Carlo Segre claims that the new power battery is safer than a lithium-ion battery because it has no flammable materials inside and the temperature is extremely easy to control. In addition, according to Argonne laboratory researcher Elena Timofeeva, the new battery stores solar and wind energy more easily. However, what we know now is that electric vehicles have a single-charge range of 40 to 100 miles. If you increase this number to 500 to 1000 miles, that is, 10 times, then pure electric vehicles can master. The fate of the automotive industry, but when this technology will be available is still unknown, success or not yet to be tested by the market.
Whether it is true or false, dream or fantasy, we should all hope that these green energy technologies can come to the people as soon as possible and take on the mission of improving and mitigating environmental problems!
