Tesla releases a new battery production line, mass popularization will take two years

Tesla recently announced the 4680 new battery and its production line video on social media, and said that this production line will be used in the super factories in Texas and Berlin. Tesla CEO Elon Musk said: 'The production of batteries is an important issue that really limits the development of sustainable energy in the future.' In October last year, Musk said that the Berlin Gigafactory in Germany will demonstrate its car manufacturing methods. The changes include the 4680 cylindrical battery cell, which can store more energy and is easier to manufacture. It is larger and more compact than the 2470 cylindrical battery currently purchased by Tesla from Panasonic and other suppliers. This is of great significance for reducing battery costs. Through the production of this battery, Tesla is expected to achieve the goal of reducing battery costs by half and achieving the goal of increasing battery production by nearly 100 times by 2030. Drew Baglino, Tesla’s senior vice president of powertrain and energy engineering, stated on last year’s 'Battery Day': 'Larger battery cells, as well as other manufacturing and design ongoing by Tesla The change will eventually increase the endurance of the car by more than 50%. 'The battery pack of an electric car usually contains thousands of battery cells. This is the most expensive part of the car. Tesla battery packs need to have a new shape and concept. design. The release of Tesla's latest battery production line video demonstrates its battery production capabilities. Previously, the outside world questioned that although Tesla is conducting research and development in the production and manufacturing process, it is difficult to predict when this new battery can be mass-produced. A veteran in the battery industry told a reporter from China Business News: 'Tesla’s innovative cylindrical battery is cheaper, and it is difficult for other battery suppliers to change the technological route. This allows Tesla to maintain originality. Advantages. But Tesla may take a lot of time to produce new batteries.' Musk also admitted that there is still a huge risk of uncertainty in the production of this new type of battery. He believes that it may take about two years for the large-scale production of batteries of this new technology in the super factories in Fremont, California, and Shanghai, China. During this period, Tesla is still strengthening battery supply cooperation with suppliers. Earlier last year, CATL stated that it would supply lithium-ion power battery products to Tesla from July 2020 to June 2022. According to information previously disclosed by LG, by 2020, LG Chem will be able to provide Tesla with 30 million batteries per month. Tesla's goal is to rapidly increase battery production to 3000 MWh per year by 2030, which is about 85 times the current capacity of the Nevada plant. The short-term goal is to produce 10 MWh of new batteries in its pilot plant within a year. Tesla currently purchases 100 MWh batteries from suppliers. Tesla also recently renewed a five-year battery research contract with the battery research laboratory of Jeff Dahn, the pioneer of lithium-ion batteries. In addition, two new battery scientists will join the team led by Dan to develop batteries for electric vehicles. Controlling battery technology and battery supply chain will determine the core competitiveness of future electric vehicle manufacturers. Among the supply parts for electric vehicles, the value of the power battery assembly system accounts for the highest proportion. As the most critical component of the electric vehicle supply chain, the car battery, the extent to which the cost of the core components of the battery can be controlled will determine whether there is still room for the price of electric cars to fall. Recently, many domestic electric vehicle manufacturers have also claimed that with new battery technology, the cruising range of electric vehicles in the future can be greatly improved. On January 15th, GAC Ian announced that its models equipped with graphene-based super fast-charge batteries can charge 80% in 8 minutes, and the standard cruising range can reach 1,000 kilometers; SAIC's Zhiji Automobile and Weilai earlier this month 'Silicon-doped lithium supplement' batteries and solid-state batteries were also released, and the cruising range can reach 1,000 kilometers. However, experts remain cautious about fully charging a 1,000-kilometer battery in a few minutes. Ouyang Minggao, an academician of the Chinese Academy of Sciences, said at the recent meeting of 100 people on electric vehicles that from the current technology, electric vehicles have a battery life of 1,000 kilometers and can be fully charged in just a few minutes. They are safe and meet the above requirements Battery products do not yet exist.
