battery 18650 genuine.Coveting Maxwell's "dry electrode technology", the energy density may exceed 500wh/kg

　　According to foreign media reports, Tesla has not elaborated on why it wants to acquire battery technology company Maxwell, but nearly two months after announcing the acquisition plan, the deal has not been completed and is even preparing to extend the deadline for the deal.

　　Last month, Tesla announced it would acquire battery manufacturer Maxwell for $4.75 per share. Maxwell was founded in 1965 as a contract research and development service provider for U.S. government agencies. It began to shift to the commercial field in the 1990s. Currently, most of the company's revenue comes from commercial products. Headquartered in San Diego, California, with European offices in Switzerland and sales and customer service offices in Germany and China, the company has more than 350 employees worldwide.

　　The media pointed out that Tesla and Maxwell have had many discussions about potential cooperation between them over the years, but the former did not start seriously considering the possibility of acquiring Maxwell until December 2018. The two companies negotiated the purchase price for several months before reaching a final agreement. But even so, some investors were dissatisfied and even filed lawsuits to try to block the deal.

　　Recently, Tesla applied to modify its acquisition offer and extended the deadline for the transaction to April 10.

　　"On March 28, 2019, Tesla announced that unless the transaction is further extended or terminated in accordance with the merger agreement, the company will extend the deadline for its previously announced tender offer to acquire Maxwell's common stock to 11 p.m. Eastern Time on April 10, 2019. Point 59."

　　Tesla did not explain the resistance to the deal, which the company initially expected could close in the second quarter.

　　Maxwell is the world's most famous supercapacitor manufacturer, among which Maxwell supercapacitors and energy storage devices are the company's flagship products. Their unique features are high power density, long service life, the ability to charge and discharge quickly, and they can still operate under extreme temperatures. Can ensure performance stability and reliability.

　　However, foreign media pointed out that Tesla may be more interested in Maxwell's "dry electrode technology."

　　In a paper published last year, Maxwell's chief chemist and battery scientist described their coating technology: "Unlike traditional slurry-cast wet-coated electrodes, Maxwell's dry electrode technology has extremely high loading rates. Thick electrodes can be produced and high-energy-density batteries can be produced without affecting physical and electrochemical properties. Maxwell's dry electrode technology exhibits better discharge capabilities than wet-coated electrodes."

　　Maxwell claims that in current demonstration batteries, its electrodes enable energy densities in excess of 300Wh/kg, and may even reach 500Wh/kg.

　　According to sources, Maxwell’s current energy density specification of 300wh/kg is already 20-40% higher than Tesla batteries, and Maxwell will have 15-25% technological progress every 2-3 years, which is why it attracts Tesla. The main reason to attract attention and investment.

　　If all goes well, Tesla will have a battery with an energy density of 500wh/kg by 2027, which will make the battery life of the company's electric vehicles ahead of other similar competitors in the world by at least 5 years.
