Swedish university develops new battery material: flexible and foldable, with 10 times the capacity of cr2032 button battery

1. Swedish university develops new battery material: flexible and foldable, with 10 times the capacity of cr2032 button battery!

With the advent of foldable phones such as Samsung Galaxy Fold, Huawei Mate X, and FlexPai. While foldable screen phones can bring us excellent visual viewing art effects, the thickness of the body and the standby time have always been problems that cannot be overcome. In the single-screen state, the body thickness is still far greater than that of regular-sized phones. The main reason is that the camera volume is limited and the battery volume is limited.

Recently, Linkoping University in Sweden has developed a super battery PowerPaper, also known as "paper battery", which broke four world records.

The battery has an extremely thin thickness, excellent ductility and stability, and can remain in good condition after repeated folding. Although the battery is small, its capacity is 26,800 mAh, which is about ten times the capacity of the iPhone battery, to ensure that the phone has a long-lasting battery life.

The principle of its realization is: the conductive polymer is reasonably matched with plant cellulose, glycerol and other substances to achieve the battery effect.

The battery has been tested in the laboratory for more than 2,000 times without any loss, and its life is more than twice that of lithium batteries.

PowerPaper has currently received 280 million yuan in funding for the overall realization of research and development and mass production.

2. Another airport order! BYD pure electric bus enters the European capital Brussels

After the Netherlands, Australia and the United States, BYD pure electric bus successfully entered Brussels Zaventem International Airport in Belgium. The first bus started operation last week. This is also the second airport in Europe for BYD pure electric bus after Amsterdam Schiphol International Airport in the Netherlands. This time, BYD won a total of 30 pure electric bus orders from Brussels Airport Group (BAC) and signed a ten-year service support contract with it to carry out in-depth cooperation on the safety and intelligent operation of buses.

This batch of airport shuttle buses provides passengers with zero-emission shuttle services between the aircraft and the terminal. It adopts the latest three-door design, increases the number of access channels, reduces the congestion of boarding and alighting, and greatly improves the transportation efficiency of vehicles. The Wi-Fi wireless network covers the entire vehicle, and passengers can enjoy free Internet access. A new USB charging port is added to provide passengers with safe and fast charging support. The on-board display screen can grasp the real-time flight dynamics. The unique design and humanized configuration "bless" in both directions to help Brussels Airport create a new travel experience for passengers.

At the same time, BYD will provide 30 sets of self-developed charging devices, which will be charged at night valley prices to meet the needs of vehicle operations. Similar equipment was also put into use at Amsterdam Schiphol International Airport in the Netherlands in June 2015. The airport currently operates 35 BYD pure electric airport shuttle buses, which is also the largest full-size zero-emission fleet in Europe at the time, promoting Schiphol Airport to become a model for international airports around the world to achieve sustainable development goals.

"Our goal is to reduce carbon dioxide emissions by 40% by 2030. BYD's new energy buses are a perfect match for Brussels Airport's green development vision. For each purchasing decision, we will focus on vehicle environmental protection and are committed to improving the passenger experience. I believe that after all 30 buses are put into use, the green travel mode of the 'EU Center' airport will be completely upgraded." said Arnaud Feist, President of Brussels Airport Group.

He Yipeng, General Manager of BYD Europe Co., Ltd., said, "Almost all airports in the world are currently facing pressure to reduce carbon emissions. BYD has a lot to do in terms of carbon emissions reduction for airport ground commuter vehicles. Mastering the core technology of the entire electric vehicle industry chain and having "smart manufacturing" experience of more than 50,000 buses, BYD has made every effort to compete for this bid and successfully stood out. I firmly believe that after Schiphol International Airport has pioneered green travel in the same industry, Brussels International Airport will also set a new benchmark for zero carbon emissions for airport shuttle buses!"

So far, BYD's pure electric buses have entered many busy airports around the world, including Sydney International Airport, Kansas City International Airport in the United States, Los Angeles International Airport, etc. BYD's pure electric vehicles have also been deployed in more than 300 cities in more than 50 countries and regions around the world, achieving the dream of new energy and the ideal of new life. In the future, they will escort more and more passengers around the world to travel in a green way.
