Authorities have identified the faculty member killed in Monday’s shooting at the University of North Carolina at Chapel Hill. UNC PhD student Tailei Qi, 34, has been charged with first-degree murder in connection with the killing of Zijie Yan, an associate professor in the Department of Applied Physical Sciences and a researcher. Mr Yan was listed as his alleged killer’s academic advisor on Mr Qi’s UNC profile, which has since been removed from the university’s website. Yan joined UNC in 2019. Before that, he was an assistant professor at Clarkson University in New York and received postdoctoral training at the University of Chicago. Mr Qi and Yan co-authored several research papers focusing on nanoscience technology. But in tweets from an account believed to belong to Mr Qi, the alleged shooter complained about “bullies and his “PI” – referring to his unnamed head of lab – being unable to handle “these girls and tattletales”. “Just have a talk with my PI and get his promise. He should have more experience to handle with these girls and tattletales,” he wrote in August 2022. Two months later in October, he referred to his PI again: “Both the group of people to say I am lazy and that to prove me working hard instead of telling me that are trying to consume my privacy. I judge their motivation is only to tell my PI then control me by taletelling.” “But it’s weird when I talked about it with my PI, he said no people spoke to him about that. so it’s nothing but some voyeurism for these people?” Yan studied undergrad at the Hauzhong University of Science and Technology, where he obtained his bachelor’s in material science and engineering and computer science in 2005. The Rensselaer Polytechnic Institute, where Yan got his master’s in physics electronics, posted a tribute on Tuesday. “He is remembered fondly by many of us that met him in the classroom, lab, or in the hallway of MRC,” a Facebook post read. “Among other things, he distinguished himself with publishing 17 journal articles in the course of his PhD study...” UNC at Chapel Hill Chancellor Kevin M Guskiewicz said in a statement on Tuesday that he has met with Yan’s family. “My leadership team and I have met with his colleagues and family to express our condolences on behalf of our campus,” the statement read. “Please join me in thinking and praying for his family and loved ones during this difficult time.” UNC police said during a press conference on Monday that a motive was not immediately evident. Mr Qi, a second-year PhD student majoring in applied physical sciences, graduated from Wuhan University in 2015 and also received a master’s in material science from Lousiana State University in 2021. The suspect joined UNC at Chapel Hill’s Yan Lab in 2022. UNC graduate student Aiden Scott, a former classmate of Mr Qi, described him as “very quiet” but “nice.” “I would have never guessed that he would be the kind of person who could possibly be capable of this kind of thing,” Mr Scott told WRAL. “Every single time he would talk to me, he seemed very nice... when I saw his face in the reports online, I was beyond shocked,” UNC has cancelled all classes on Tuesday as an investigation remains ongoing. Mr Qi is expected to appear in court later today.

A battery startup is aiming to be the first company in the world to mass produce electric vehicle batteries with a range of 1,000km – roughly double the current standard. China-based Gotion High Tech, which is a supplier to Volkswagen, unveiled its new L600 LMFP Astroinno battery at its annual technology conference, claiming that mass production will begin in 2024. The lithium-manganese-iron-phosphate (LMFP) battery has already passed all necessary safety tests, the company said, and has a life cycle of 4,000 charge-discharge cycles – making it suitable for everyday electric cars. The 1,000km range from a single charge gives the battery a potential lifetime range of 4 million kilometres, far exceeding the average lifespan of a car. Its single-charge range is also equivalent to records set by customised electric prototypes, such as the Mercedes-Benz Vision EQXX that broke a range record by travelling from Germany to the UK on a single charge last year. It took 10 years of in-house research to make the technology commercially viable, using new electrolyte additives and state-of-the-art technology to overcome previous issues with this type of battery. Until now, LMFP materials have suffered low conductivity, low compaction density and manganese dissolution at high temperatures, meaning they were too inefficient and unwieldy to use in EVs. Despite these challenges, the enormous potential of the technology has drawn the attention of researchers and industry watchers. “In recent years, lithium iron phosphate (LFP) technology has regained the recognition of the market with market share continuing to increase,” said Dr Cheng Qian, executive president of the International Business Unit of Gotion High-Tech. “Meanwhile, the energy density growth of mass-produced LFP batteries has encountered bottlenecks, and further improvement requires an upgrade of the chemical system, so [our system] was developed.” The company also made other breakthroughs with the battery’s design, which reduced the number of structural parts by 45 per cent and lowered their weight by nearly a third. Wiring for the battery pack has also dropped from 303 metres to just 80 metres thanks to the innovative design. It is not clear which vehicles the battery will first appear in, though Gotion High Tech is planning a $2.3 billion battery factory in the US.
