With the change of global environment and climate, protecting the environment, reducing pollution and relieving energy pressure have become one of the important development directions of automobile industry, and the development of new energy vehicles has been promoted to the national strategic level. Even the investment outlet of the capital market is eyeing the field of new energy vehicles. What's more worth mentioning is that Tesla's concept stocks have soared this year, and Tesla's disclosure of new battery technologies has made the power battery industry chain a major direction of focus. Driven by the Tesla market, the share price of American electric vehicle giant Tesla hit a new high this year, and the upward trend of industrial development has not changed. On February 2 1 day, Huaxia CSI new energy vehicle ETF was formally established. The announcement shows that its subscription amount is about 10763 billion yuan, which means that about1000 billion yuan will buy 25 new energy vehicle concept stocks in disguise. Tesla is undoubtedly a good help for the position of new energy vehicles in the automotive field.

On July 1 2003, martin eberhard and his long-term business partner Mark Tapenning jointly established Tesla Motors. It took Tesla about five years to do research and development. For example, his proud endurance comes from a battery pack consisting of more than 7,000 batteries. Individual battery damage will not affect others. This battery control system is Tesla's own, and this model can also ensure that it can use the most advanced batteries to equip Tesla electric vehicles at any time.

Elon Musk, CEO of Tesla, an American electric car manufacturer? Musk) said that in 20 16, it was announced that Tesla would launch new models including Semi electric trucks, electric buses, electric pickups and a compact SUV. In the same year, Tesla officially announced that it agreed to merge with solar panel manufacturer SolarCity by all-stock trading. On July 20 18 18, Tesla signed an investment agreement with Shanghai Municipality, Lingang Management Committee and Lingang Group on the pure electric vehicle project.

A few days ago, Tesla announced that it is expected to release its self-developed battery in April, and the cobalt content may be zero. Later, there was a voice in the market that Tesla might choose lithium ferrous phosphate as the technical direction of the new battery, but on the evening of February 2 1, the official account of Tesla Shanghai Factory replied to this voice on social media: "No cobalt does not mean that it must be lithium ferrous phosphate." This led to further speculation about Tesla's new battery. Some people related to Tesla also told the Securities Times reporter: "The new battery independently developed is a combination of dry battery technology and super capacitor, and the specific components are expected to be explained at the Tesla battery meeting in April." In fact, as early as 2065438+February 2009, Tesla announced the acquisition of 79% equity of Maxwell, a supercapacitor manufacturer, to enhance its expertise in the field of energy storage and transmission.

Technical direction of Tesla's self-built batteries: In the field of batteries, Tesla has been constantly seeking the most cutting-edge technical direction. The latest public information shows that Maxwell dry electrode and supercapacitor will be the technical direction of Tesla's self-built battery. Dry electrode technology can increase the energy density of Maxwell monomer from 300Wh/kg to 500Wh/kg. Solvent-free, the battery life is doubled, solvent stirring and drying equipment is reduced, and the cost is reduced by 10~20%. Because of its cycle life of more than 654.38+ 10,000 cycles, power density of 654.38+00 times that of lithium batteries and wider temperature range, supercapacitors are suitable for occasions with high power density requirements, and will be combined with lithium batteries to form new batteries.

I still remember that on May 9, 20 13, Musk wrote in his personal blog, "I just want to say thank you to customers and investors. You gave Tesla a chance to travel through the long night. Without you, we can't go today. " After many years, Tesla has now become an important factor in investing10 billion to grab the ETF of new energy vehicles.
