Researchers at Monash University have developed an efficient lithium-sulphur (Li-S) battery, according to a new study.

The battery that     1     (be) able to power a smartphone for up to 5 days outperforms (超过) current lithium-ion (锂离子) batteries by more than four times. In addition     2     better performance, the new battery has less environmental impact than current lithium-ion batteries.

The international research team     3     (lead) by Dr. Mahdokht Shaibani from Monash University have an approved filed patent for their production process. German partners Fraunhofer Institute for Material and Beam Technology     4     (successful) made the first model batteries.

Professor Mainak Majumder from Monash University said the research could have     5     huge impact on the way phones, cars and computers     6     (make) in the future.

“This     7     (innovate) in batteries will provide all Australians with a cleaner and more     8     (depend) energy market,” Professor Majumder said.

“Our research team has received more than $2.5 million in funding from the government and international industry partners     9     (test) this battery technology from this year,     10     is what we are most excited about,” he added.

Imagine learning football skills without going to the field, or     1     (get) an alert from your car about a danger not in sight — such eye-opening, cutting-edge technologies were brought to the fifth China International Import Expo (CIIE) in Shanghai.

At a VR game demonstration, visitors could walk and run in the virtual world with a special equipment. “The VR equipment     2     (be) actually widely used for training in     3     (vary) fields, including military, police, firefighting, power sector and coal mining,” said Carol Zhang, senior project manager with KAT VR.

At another experience area, the infinite     4     (possibility) of future travel were demonstrated by vehicles that combined many intelligent technologies, such as autonomous driving, image sensors, camera modules and intelligent connection.

At a booth showing a virtual sports event, there was a camera in the corner through     5     the data created by the athletes during exercise was captured in real-time, forming     6     3D human body model to help them find the     7     (good) moves.

The world’s first multitasking high-tech robot service station also debuted (首次亮相) at the fifth CIIE, providing     8     (guide), security inspection, item recycling and other services.     9     (control) by a smart system, the 46 robots     10     (send) in real time to perform numerous tasks in different scenarios.

It took less than an hour for Bai Haoran, a junior student at Tongji University in Shanghai, and his classmate Zhang Wanlin    1    (send) a mobile power box to a collection point in the city’s Pudong New Area on Monday.

It marked the last step of a five-day process, during     2    he and his classmates made the power box to aid relief work in earthquake-hit areas of Türkiye.

On Feb.9, Bai,    3    (study) at the Sino-German College of Applied Sciences of Tongji University, got to know that the earthquake-hit area    4    (bad) needed mobile power.

The 20-year-old had a brief discussion     5    his classmate Zhang, and as even — strong research and development team     6    (set) up. Since the new semester had not started, most of the students had not returned to school. The team was divided into online and offline groups.

Though moveable power boxes are available on the market, Bai said their design is specially-made as they have taken into     7    (consider) local sunshine and disaster relief needs.

The team decided that     8    best use of the power box, which weighs around 15 kilograms     9    is equipped with a 10-wattLED light, was that it could be able to provide 30 to 40 straight hours of light if fully recharged. On Monday morning, after running the power box through    10    (it) last test, Bai and Zhang had it packed and delivered to Türkiye by air.

Robotic age draws closer

These days, robots are     1     (common) than you might think. Consider the Roomba,     2     robotic vacuum cleaner (真空吸尘器) which cleans floors on its own.

“We wanted to make something simple     3     people could use every day,” says Greiner, co-founder of iRobot, the company that makes the smart vacuum cleaner.“And that's what inspired us to build the Roomba.”

Some robots like the Roomba are already very common in many US households.

iRobot makes everything from the Roomba to robots that someday might become a part of us.

“You can have robotics     4     (equip) into your body, to get back that arm or leg that you've lost, either in some accident or disease,”says Greiner.

Although robots have been developed mainly for military     5     (apply), civilian uses for the technology are growing, according to Michael Toscano, president of the Association for Unmanned(自控的) Vehicle Systems International.

Unmanned systems allow human beings to do their tasks     6     an extension of their hands, their eyes and their ears,”

“We can put them in the ocean and they     7     (swim) for eight or nine months, collecting data and monitoring ocean pollution,”says Hudson of iRobot.

Recently the US government's Defence Advanced Research Projects Agency (DARPA) displayed a“robotic man”.

Instead of depending on the remote control, DARPA's “robotic man”can     8     (actual) look at some blocks, find one with a special pattern, and move it to a new location. Mandelbaum, DARPA's project manager, says more     9     (challenge) tasks lie ahead.

Someday, a DARPA robot might find a hidden bomb or help a disabled person select a shirt and button     10    .
