Elon Musk said the interests of the US and China are “intertwined like conjoined twins” during his surprise visit to China on Tuesday amid strained diplomatic ties between the countries. The Tesla billionaire reached Beijing in his first visit to the country in over three years, visited China’s top ministries and discussed electric vehicles. Mr Musk also met China’s foreign, commerce, and industry ministers and dined with Zeng Yuqun, the chairman of top battery supplier CATL. The visit garnered a lot of attention in China and revealed adulation for Mr Musk from Chinese social media users, even as the relationship between Washington and Beijing plummeted. “The interests of the United States and China are intertwined like conjoined twins,” Mr Musk was quoted as saying by the foreign ministry of China. He was later also quoted by the country’s commerce ministry as saying that relations between the two countries were not a zero-sum game in which one side must lose if the other were to win. While little is known of the discussions the Twitter chief is having – as he remains unusually quiet on social media – Mr Musk and industry minister Jin Zhuanglong “exchanged views on the development of new energy vehicles and intelligent networked vehicles”, said the ministry. China, responsible for half of all global electric vehicle sales, serves as the location for Tesla’s first factory outside the US. The company reportedly submitted applications to expand its production facilities in Shanghai. Mr Musk’s plans were still awaiting approval as he earlier said it faces some “constraints”. The talks are expected to be aimed at easing this expansion, believe observers. The billionaire’s visit has also generated a lot of interest among China’s netizens. Some called him “a pioneer” and “Brother Ma”, in an oblique reference to Jack Ma, while others said he should become the next US president. “He’s a global idol,” wrote one Chinese social media user. “Elon Musk is just great, if only China could have someone like Elon Musk,” said another. In recent months, foreign companies have been facing increasing pressure in China, with a recent crackdown on international consulting firms. Both the US and China have also imposed restrictions on each other’s chipmakers. American companies are also facing pressure from outside as increasing threats of military escalation with Taiwan forces businesses to diversify their supply chains away from China. Mr Musk, however, touted the Asian country’s development as its ministers assured they were looking at increased cooperation. The Chinese government statement cited Mr Musk as saying Tesla was willing to expand its business in China and “opposes decoupling” – a reference to fears the world may split into multiple markets with incompatible products. On Tuesday, foreign minister Qin Gang told Mr Musk that China will “unswervingly promote high-level opening up” and create a “market-oriented, law-based and internationalised business environment”, said the government statement. “China’s development is an opportunity for the world,” it said. Mr Qin also told Mr Musk that China’s electric vehicle market “has broad prospects for development”. Mr Musk is expected to meet other senior Chinese officials and visit the Shanghai plant later in the week, reported Reuters citing sources. With China's economy also experiencing a slowdown and facing internal and external challenges, like anti-monopoly measures and the US-Chinese political tensions respectively, the ruling Communist Party has been engaging with more prominent CEOs off late. Chinese premier Li Qiang earlier held discussions with Apple’s Tim Cook, Pfizer’s Albert Bourla, Rio Tinto’s Jakob Stausholm and Toshiaki Higashihara of Hitachi, reiterating China's commitment to creating a favourable business environment.

The key to longer-lasting batteries may lie in soap, according to a new study. Scientists have developed a new promising substance used for designing batteries. They said it acts in a manner similar to soap removing grease, dirt and germs. Localised high-concentration electrolytes could be the “missing piece” that fully open the door to building longer-lasting batteries, said a recent study published in the journal Nature Materials. The key to longer-lasting batteries may lie in understanding how soap gets rid of dirt. It forms tiny structures called micelles that act as a bridge between water and what is being cleaned away by wrapping them into small structures. Scientists from Brown University said a similar process plays out in localised high-concentration electrolytes – described as one of the most promising substances for designing batteries. Electrolytes are key in the energy-storing process as they allow an electrical charge to pass between a battery’s two terminals. This sparks the chemical reaction needed to convert stored chemical energy to electricity. Batteries made from lithium metal have a greater energy storage capacity than today’s lithium-ion batteries. But the electrolytes commonly used to power lithium-ion batteries don’t do this effectively in metal-based batteries, researchers explained. “The big picture is that we want to improve and increase the energy density for batteries, meaning how much energy they store per cycle and how many cycles the battery lasts,” said study co-author Yue Qi from Brown University. “To do this, materials inside of traditional batteries need to be replaced to make long-life batteries that store more energy a reality – think batteries that can power a phone for a week or more, or electric vehicles that go for 500 miles,” Dr Qi said. Electrolytes for lithium-ion batteries are made of low-concentration salt dissolved in a liquid solvent. The new type of electrolytes, however, are created by mixing high concentrations of salt in a solvent with another liquid called a diluent. Scientists said this makes the electrolyte flow better so the power of the battery can be maintained. They also found the electrolyte functions like soap. “The paper provides a unified theory to why this electrolyte works better and the key understanding of it came by finding that micelle-like structures form within this electrolyte – like they do with soap,” said study co-author Bin Li from the Oak Ridge National Laboratory. “Here we see that the role of the soap or surfactant is played by the solvent that binds both the diluent and the salt,” Dr Li explained, “wrapping itself around the higher concentration salt in the center of the micelle”. While in lab tests, this type of electrolyte has shown promising results, how it works has remained elusive. This has put a cap on how effective it can be and how it can be further developed. The new understanding has, however, helped scientists develop the right concentrations needed to bring about optimal reactions for the batteries. “The concept of the micelle may be new for the electrolyte, but it’s actually very common for our daily life,” Dr Qi said. “Now we have a theory, and we have guidelines to get interactions we want from the salt, the solvent and the diluent in the electrolyte, and what concentration they have to be at and how you mix them.” Researchers said this new understanding could lead to introducing a proper balance of the three battery ingredients and also help extend the life of lithium-metal batteries.
