A gun attack in a mining area in the Democratic Republic of Congo (DRC) has killed three Chinese nationals, the official news agency Xinhua reported on Monday.

The attack took place on Saturday in the northeastern province of Ituri, which borders Uganda and South Sudan, Xinhua said, citing the Chinese embassy.

It did not name the mine in question or the company operating it.

The DRC is the world’s biggest producer of mined cobalt – a key ingredient in batteries for electric vehicles – and one of Africa’s biggest copper producers, although its key copper-cobalt producing region is in the southwest, far from the site of the attack.

The country has attracted billions of dollars in investment from Chinese miners in recent years despite security risks.

Canadian gold miner Banro, which owns mines in Maniema, a DRC province south of Ituri, suspended operations last year after several of its mines were overrun by armed rebels.

The Chinese embassy has asked the Congolese government to “take effective measures to protect the lives and property of Chinese citizens” in the DRC, as well as to expedite an investigation into the killings, Xinhua said, noting that the embassy had repeatedly advised Chinese citizens against travel to Ituri due to the presence of armed groups.

The embassy did not immediately respond to a request for comment on Monday, a public holiday in China.

Factbox – The world’s biggest electric vehicle battery makers

(Reuters) – Asian companies dominate the market for electric vehicle (EV) batteries and they are expanding their production capacity in Europe, China and the United States in a fight to win lucrative contracts from global automakers.

Some carmakers worry, however, there won’t be enough batteries for all the EVs they plan to launch in the coming years and a bitter row between South Korea’s SK Innovation and LG Chem risks exacerbating the potential shortfall.

Below are details of the world’s leading EV battery makers with details of their customers and expansion plans:

CATL

China’s Contemporary Amperex Technology (CATL), the world’s biggest EV battery maker, counts BMW (BMWG.DE), Volkswagen (VOWG_p.DE), Daimler (DAIGn.DE) – which makes Mercedes cars – Volvo, Toyota Motor Corp (7203.T) and Honda Motor Co (7267.T) among its customers.

The company emerged as a major force partly thanks to Beijing’s policy of only subsidising vehicles equipped with Chinese batteries in the world’s biggest EV market. Beijing is phasing out EV subsidies next year.

CATL, which operates factories in China, is building its first overseas plant in Germany and is considering a U.S. factory.

PANASONIC CORP (6752.T)

Japan’s Panasonic, a supplier of U.S. EV pioneer Tesla (TSLA.O), said it has installed equipment to ramp up production at Tesla’s Nevada plant to 35 GWh from its current production of around 30 GWh as of late October. Panasonic has said it is investing about $1.6 billion in the factory.

Panasonic also produces EV batteries in Japan, China and plans to shift some of its plants to a new joint venture with Toyota. Panasonic’s clients also include Honda and Ford Motor Company (F.N).

BYD CO LTD (002594.SZ)

China’s BYD, which is backed by U.S. investor Warren Buffett, is also one of the world’s biggest EV battery makers. It mainly uses them in-house for its own cars and buses. BYD said last year it is was considering cell production in Europe.

LG CHEM LTD (051910.KS)

The South Korean firm was an early industry mover, winning a contract to supply General Motor’s (GM.N) Volt in 2008. It also supplies Ford, Renault (RENA.PA), Hyundai Motor (005380.KS), Tesla, Volkswagen and Volvo.

It is investing 3.3 trillion won ($2.8 billion) to build and expand production facilities near Tesla’s plant in Shanghai. It has a joint venture (JV) in China with Geely Automobile Holdings (0175.HK), which makes Volvos, and is in talks with other carmakers about JVs in major markets.

The firm is considering building a second U.S. factory in addition to its facility in Michigan and is expanding its plant in Poland.

SAMSUNG SDI CO LTD (006400.KS) Samsung SDI an affiliate of South Korean tech giant Samsung Electronics (005930.KS), has EV battery plants in South Korea, China and Hungary, which supply customers such as BMW (BMWG.DE), Volvo and Volkswagen. Samsung SDI is investing about 1.2 billion euros ($1.3 billion) to expand its factory in Hungary though the EU is investigating whether Budapest’s financial support complies with the bloc’s state aid rules.

Samsung started production last year on the Hungary plant, which will produce batteries for 50,000 EVs a year.

SK INNOVATION CO LTD (096770.KS) LG Chem’s cross-town rival SK Innovation supplies batteries to Volkswagen, Daimler and Kia Motors (000270.KS), as well as Jaguar Land Rover [TAMOJL.UL] and Ferrari (RACE.MI).

An oil refiner that came to the battery industry late, SKI is investing about $3.9 billion to build three plants in the United States, China and Hungary, with a goal of expanding its annual production capacity to 33 GWh by 2022.

SKI currently operates one battery factory in South Korea, with a capacity of 4.7 GWh annually.

It set up a joint venture with Beijing Automotive Industry Corporation (BAIC) of China in August 2018 and another Chinese partner. It is in talks with Volkswagen about another battery JV and is building a $1.7 billion factory in the U.S. state of Georgia, not far from Volkswagen’s Chattanooga plant.

Chinese engineers follow the Sea Dragon with new submersible that can ‘fly’ through water like a plane in the air

  • Developers say their prototype craft could dive to 1,000 metres in five minutes
  • Liu Kaizhou, who also worked the Jiaolong submersible, says ‘We are in uncharted water’

Chinese engineers say they are developing a radical design for a super-fast robot submersible which the project leader, who worked on the manned deep-sea vessel Jiaolong, or Sea Dragon, claims can “fly” in water like a plane travels through the air.

At 3 metres (9.8ft) long, the prototype consists of a cigar-shaped body, with a guidance system in the bow and a jet plane style rudder and a propeller in the stern.

Outriggers house batteries and two more propellers. These are attached to the body by wing-like planes that the developers said will give the vessel the kind of lift in water that takes an aeroplane into the air and back to the earth.

Developers said the prototype will be capable of 10 knots and could dive to a depth of 1,000 metres (3,281 feet) – or surface from that depth – at about three metres a second, taking about 5½ minutes.

Professor Liu Kaizhou, lead scientist of the project at the Shenyang Institute of Automation, part of the Chinese Academy of Sciences in Liaoning province, said the design had great potential.

If a traditional submarine was like an air balloon, he said, the prototype was like an aircraft. “It is technically flying, fast and freely, like a plane for the water.”

The prototype has 20 major components on board, including a computer, and communications and surveillance equipment. These were all developed and tested by the team, but getting them to work together posed some unexpected challenges, Liu said, meaning the transition to operations in a tough marine environment was some time away.

Underwater station could be a game changer, Chinese scientist says

“We aim to make the first open sea test in about a year,” he said.

The submersible can be powered by conventional batteries or a chemical engine that mixes lithium and sulphur hexafluoride to produce heated steam for electrical generators – an energy source often used by torpedoes.

Funded by the Ministry of Science and Technology from 2017, the project was driven by China’s growing ambition to become a superpower in the world’s oceans.

The team said their submersible had the potential to become the backbone of China’s search-and-rescue operations at sea, naval intelligence gathering, high-precision sea floor mapping, or to transport minerals from the seabed to the surface.

Professor Du Tezhuan, a researcher in fluid dynamics at the Institute of Mechanics of the Chinese Academy of Sciences in Beijing, said the design was a bold one but it posed the research team many hard questions.

The density of water was much higher than that of air, he said, which meant the vessel would encounter more drag and would need a strong power source.

“Without sufficient speed, the lift will be weak, and to reach high speeds, lots of energy will be needed. Flying in water is not as easy as flying in the air,” said Du, who was not involved in the project.

Why Beijing is speeding up underwater drone tests in the South China Sea

“But in theory it should work. It is worth a try.”

Liu – who led the design of the autopilot system that can take the Jiaolong to depths of more than 7,000 metres (23,000 ft) – said that after tests on the prototype were complete, other innovations were possible. These included covering the vessel with air bubbles to reduce friction.

“This technology is brand new,” he said. “We are in uncharted water and we are excited by the challenges.”
