According to foreign media reports, due to the alarming development speed of the battery industry, some battery technologies may become obsolete before entering the market. Teams of scientists from San Francisco to Shenzhen are experimenting with new chemical processes to improve traditional lithium-ion batteries and trying to find new ways to store electricity for later use. Investors in these projects began to worry that they might have chosen the wrong technology. This has turned the debate over “stranded assets” on its head. Until now, the term has generally been used to refer to fossil fuel projects that may become unprofitable due to tighter pollution regulations. In the future, the way energy storage devices are manufactured will change dramatically, meaning investment in the battery industry may also be unprofitable, even though batteries are at the heart of changing the way energy systems operate. "If you suddenly want to move to a technology that provides higher energy density, then people will want to adopt that quickly, which may mean they will have to invest in remanufactured equipment again," said James Frith, an energy storage analyst at Bloomberg NEF. Worse case, you might have to redesign the entire factory." Investment in startups developing new battery cells rose to more than $1.5 billion in the first half of this year, almost as much as in 2017, according to Cleantech Group. twice. Volkswagen Group, Hyundai Motor and the Renault-Nissan-Mitsubishi alliance have invested in battery companies. Japan's New Energy and Industrial Technology Research and Development Organization announced that it will invest US$90 million in solid-state equipment research in cooperation with multiple universities and manufacturers. Peter Carlsson, founder and CEO of NorthVolt, said, "There is currently a lot of money invested in battery research, which will ultimately lead to technological advancement. We are building a production platform to have the ability to continue to develop and evolve." NorthVolt Battery Company is headquartered in Stockholm , is spending 4 billion euros ($4.6 billion) to build a battery manufacturing plant in the Nordic region. Not all technologies are successful. Across the battery industry, thousands of different systems are being tested by large manufacturing companies, start-ups and universities. Even the lithium-ion batteries used in most electric cars and cell phones have different manufacturing processes. TJ Winter, chief manager of Fluence, a U.S.-based energy storage supplier, said, "Lithium electrons have different types, different chemical reactions, and even the way they are composed in chemical reactions is different. It takes us just as much time to screen and develop projects. For quite some time." Competition in the battery industry is growing as automakers electrify more models and energy storage units become more common in homes and businesses. According to Bloomberg NEF forecasts, demand for battery capacity will increase from 100 gigawatt hours today to 1,784 gigawatt hours by 2030. Approximately $16.7 billion has been spent globally to install equipment in traditional battery factories, with another $42 billion of equipment expected to be operational by 2022. The International Energy Agency said that lithium-ion batteries will remain the main source of power for electric vehicles and storage devices in the next 10 years. The organization said in its "Electric Vehicle Outlook" report that after 2025, new technologies may enter the market. As a result, existing lithium-ion technology may become unpopular, and new projects may not meet the needs of existing companies. Regardless, some investors may end up using batteries that are not economical. Jeff Chamberlain, CEO of Volta Energy Technology Investment Fund, which focuses on next-generation storage technologies, said: "The global bandwidth for manufacturing lithium batteries is huge. We are seeing many investors betting on technologies that require new manufacturing processes. We think this "It's a flaw because right now we're making high-capacity batteries." The process of getting batteries from the lab to the market is slow and expensive. To save cost and weight in battery packs, scientists are replacing expensive metals like manganese and nickel with more abundant substances like sulfur and oxygen. New York startup Conamix recently raised $2 million to try to create cobalt-free batteries. Cobalt is a rare earth metal that is a key ingredient in charging, but it is mostly mined in the war-torn Democratic Republic of Congo. Jeff McDermott, managing partner of Green Technology Capital Advisors, said other technologies "may not be able to achieve scale due to the low price of lithium electronics. Lithium-ion batteries will undoubtedly put pressure on other technologies on price. Technologies that compete with lithium electronics will only There will be several, not dozens, because battery technology requires mass production to reduce costs." Equinor, Norway's largest energy company, has been screening energy storage-focused start-ups for the past three years, but so far has not Invest in any developer. Bala Nagarajan, director of Equinor's in-house energy venture capital fund, said, "Energy storage is a priority for us and there is still a need for technological improvements in the adoption of clean energy and electric vehicles. Is it possible that our future investments in storage technology will fail? The answer That’s for sure.”
