Có một quá trình tái chế mới chỉ cần một nửa năng lượng so với kỹ thuật thông thường và sản xuất những vật liệu âm cực sẵn sàng để sử dụng.
Một quá trình tái chế mới đơn giản phục hồi cực âm của pin lithium cũ chỉ sử dụng một nửa năng lượng của quá trình tái chế hiện tại. Không giống như những phương pháp tái chế hiện nay, phá vỡ cực âm thành những phần tử riêng biệt mà rồi lại cần ghép chúng lại một lần nữa, công nghệ mới tạo ra hợp chất mà đã sẵn sàng để đi vào một cục pin mới.
Phương pháp này sử dụng được trong pin lithium coban oxit dung trong máy tính xách tay và điện thoại thông minh, và trong pin phức hợp lithium-niken-mangan-coban có trong xe điện. Tiếp tục đọc “Quá trình tái chế đơn giản, hiệu quả năng lượng cho pin Lithium-Ion”
Denmark announced a ban on new internal combustion engine cars this month, joining at least 13 other nations now looking to limit ICE sales. The Danish ICE ban will come into effect in 2030 and will prohibit the sale of new fossil-fueled cars.
Announcing the move, Denmark’s Prime Minister Lars Lokke Rasmussen said: “I’m all for cars, but they shouldn’t ruin the environment.”
By the time the ban comes into force, Denmark should have at least a million electric or hybrid cars on its roads, he said.
The country, which has a population of less than 5.8 million and is aiming to rely on carbon-free electricity by 2050, has seen sales of non-polluting vehicles declining after Rasmussen’s center-right government phased out subsidies, Bloomberg reported.

Timeline: History of the Electric Car
Scottish inventor Robert Anderson invents the first crude electric carriage powered by non-rechargeable primary cells.
American Thomas Davenport is credited with building the first practical electric vehicle — a small locomotive.
French physicist Gaston Planté invents the rechargeable lead-acid storage battery. In 1881, his countryman Camille Faure will improve the storage battery’s ability to supply current and invent the basic lead-acid battery used in automobiles.

Car and tech companies are scrambling for supplies of cobalt, a mineral they need to power electric vehicles and smartphones. But they have a problem: Much of the cobalt used in lithium-ion batteries comes from a country where children work in mines.
Is there such a thing as an ethical electric car?
A CNN investigation has found that child labor is still being used to mine the valuable mineral at some operations in the Democratic Republic of Congo (DRC). This country produces about two-thirds of the world’s cobalt and is estimated to sit atop half of the globe’s reserves.

The appetite for electric cars is driving a boom in small-scale cobalt production in the Democratic Republic of Congo, where some mines have been found to be dangerous and employ child labor.
Production from so-called artisanal mines probably rose by at least half last year, according to the estimates of officials at three of the biggest international suppliers of the metal, who asked not to be named because they’re not authorized to speak on the matter. State-owned miner Gecamines estimates artisanal output accounted for as much as a quarter of the country’s total production in 2017.

China made more than half of EV purchases in the third quarter
Bloomberg New Energy Finance expects 1 million sold this year
Electric vehicles sales surged to a record in the third quarter, largely driven by strong demand in China.
Sales of battery electric vehicles and plug-in hybrids exceeded 287,000 units in the three months ended in September, 63 percent higher than the same quarter a year ago and up 23 percent from the second quarter, according to a report released Tuesday by Bloomberg New Energy Finance. China accounted for more than half of global sales as its market for electric cars doubled amid government efforts to curb pollution.
“The Chinese government is very focused on pushing up EV sales,” said Aleksandra O’Donovan, advanced transport analyst at BNEF and one of the authors of the report. “One reason for that is the local pollution levels in the cities, and a second is for China to build domestic heroes to compete internationally in this market.”
BNEF expects global EV sales to surpass 1 million units this year for the first time. The market for electrified transport is starting to pick up speed as charging infrastructure becomes more accessible and manufacturers roll out models with longer driving ranges. In 2017, many established carmakers from Jaguar Land Rover to Volvo Cars announced plans to bring electric versions of their vehicles to market in the next few years.

adb.org_Imagine you’re buying a car, and the manufacturer forces you to purchase not only the vehicle itself but also demanded you pay upfront for 10 years worth of fuel. About $25,000 for the car and another $50,000 for the gas. Would you still purchase the car? Absolutely not, unless the gasoline was given at a discount price, right?
Anyone shopping for an electric car could be forgiven for thinking that manufacturers are asking to pay upfront for future energy use. These vehicles are still on average about 35% more expensive than non-electric cars – despite gradually declining battery prices and the promise of practically zero maintenance fees.
