Purchasing new patents Tesla's self-produced batteries to speed up

Tesla has made new moves in self-produced batteries. Foreign media reported that Tesla spent $3 to purchase three patent applications from the Canadian small battery company Springpower International to help it reduce battery manufacturing costs. It is reported that Tesla has obtained the following patents: an innovative production process for rechargeable lithium ion battery cathode materials (US62/899,677), a process for recovering materials from waste rechargeable lithium ion batteries (US62/951,735), lithium ion battery cathode materials Preparation method (US62/652,516). One of the problems Tesla wants to solve is to drastically reduce the water consumption and related costs in the process of producing cathode materials. Tesla said that a large amount of polluted water containing ammonia, metal particles and other chemicals will appear in the production of cathode materials. The Springpower process cleverly circulates the chemical solution, so no water treatment can help Tesla reduce 66% of the production cost, thereby reducing battery manufacturing costs. In addition, using the same process, Tesla can also directly use metal powder from recycled batteries to obtain purer battery cells. According to reports, the low purchase price of these patents may be due to patents being applied for at the time of purchase and no formal authorization has been confirmed. However, in addition to the purchase of patents, Tesla seems to have also acquired the entire company of Springpower. According to the information, Springpower researchers have changed their LinkedIn profile, indicating that they are now working at Tesla. Springpower also did not confirm or deny the acquisition. After the acquisition of Springpower, Tesla is expected to further enhance its capabilities in battery Ru0026D and production, and accelerate its pace of self-produced batteries. On 'Battery DayThe battery life is increased by 54%, and the cost of electricity per kilowatt-hour is reduced by 56%. Among them, Tesla mentioned a plan to produce the battery on a large scale, and proposed a construction goal of reaching 100 GWh of battery output in 2022 and 3 TWh in 2030. Prior to this, Tesla had acquired HibarSystems, a Canadian battery manufacturing equipment and engineering technology company, and Maxwell Technologies, a dry electrode technology company, as well as ATWAutomation, a German automotive battery pack manufacturer, and signed an equipment purchase with a Chinese equipment company. protocol. In addition, Tesla also signed long-term purchase orders for cobalt lithium raw materials with upstream material companies such as Glencore, Ganfeng Lithium, Australian lithium mining company Kidman, Piedmont Lithium, and Canadian mining company GigaMetals. In order to ensure the sustainable and stable supply of raw materials, Tesla is also deploying lithium-ion battery recycling. Recently, it has launched a battery recycling service. It promises that scrapped lithium-ion batteries will be treated specifically to achieve 100% recycling of raw materials. In terms of battery technology, Tesla has also reached a battery research agreement with Canadian lithium-ion battery pioneer Jeff Dahn to jointly develop new battery technologies. Judging from the above layout, Tesla’s research and development of new battery technology and acquisition of battery manufacturing-related companies are of unique significance, far beyond the general main engine factory’s attention to power lithium batteries, which means that Tesla has already made self-produced batteries. Prepared, the self-production plan of battery cells is accelerated.
