Enterprises start to develop next-generation batteries -Lithium - Ion Battery Equipment

According to foreign media reports, there is nothing more suitable for powering smartphones or Tesla than lithium batteries. Since its first launch in 1991, rechargeable lithium batteries have become daily scientific and technological equipment and electric vehicles. General standard of vehicle power supply. Data shows that most of the more than 3 million electric vehicles in the world are driven by lithium battery batteries. However, as the world moves towards the future power era, it is clear that we need better technology than lithium battery batteries to meet the future needs of mankind.(Lithium - Ion Battery Equipment)

"Lithium battery technology has almost reached its limit. If you really want to improve the energy density, you must use a completely different technology," said Yifei Mo, a professor of materials science and engineering at the University of Maryland. "Higher energy density means cheaper, lighter batteries that last longer on a single charge."

Fortunately, some battery start-ups are working hard to develop better battery technology. Their ideal new battery has lower cost, higher energy density and better performance, and is suitable for industrial and consumer technology products, as well as electric vehicles with faster charging speed and longer driving distance.

Since this year, several start-ups that have developed battery technology believe that they have mastered better battery technology than lithium batteries, and plan to introduce them to the commercial market.

Gene GeneBerdichevsky, CEO of Sila Nanotechnology, said: "It took us 8 years and about 35,000 times of material trials to make some achievements that can be commercialized."

In fact, Sila nanotechnology is only one of several battery start-ups that have recently received substantial funding to continue to optimize their battery technology. Last year, the company in Alameda, California, obtained a round D financing of 70 million dollars from a number of investors, including Siemens Global Wind, to build its first commercial production line of silicon anode batteries.

It should be noted that Berdychevsky, a mechanical and energy engineer, was the seventh employee of Tesla ten years ago and was responsible for leading the design of the battery system of Tesla Roadster.

According to the analysis, the lithium battery revolution that is gradually emerging has been brewing for about 10 years. It is only now that start-ups are ready for the commercialization of these new technologies.

"The materials needed for a car are equivalent to 10000 smart phones or 1000 smart watches," said Berdychevsky. "We will start with consumer devices and gradually expand our cooperation with automotive partners in the next five years."

BMW has now become one of Sila's automobile partners.

At present, lithium batteries are subject to various restrictions in terms of material composition and physical energy density. The new battery technology tries to improve the safety and energy efficiency of lithium batteries, that is, if the batteries are overheated or damaged, there is no risk of fire.

A new battery technology is solid state battery. This kind of battery not only uses lithium metal material to replace graphite anode, but also uses a solid piece (usually ceramic, glass or flame retardant polymer) to replace liquid electrolyte and diaphragm. In the industry, SolidPower, a solid-state battery manufacturer headquartered in Colorado, took the lead in adopting this method, and obtained a round A financing of 20 million dollars in 2018.

According to SolidPower executives, the battery they are developing will increase the energy density by at least 50%.

The mysterious Stanford University derivative company Quantum scape is also working with the public to develop a solid state battery. Last year, Volkswagen increased its holdings of the former by $100 million. The San Jose based startup is now valued at $1.75 billion, according to PitchBook.

According to media reports, the battery of Quantumscape will enable Volkswagen's E-Golf model to travel 466 miles (about 750 kilometers) on a single charge, making it comparable to the range of traditional gasoline powered vehicles. According to Volkswagen, the battery of Quantumscape will also be lighter than the existing lithium battery and have a faster charging speed.

However, as a Nissan vice president said last year, the new generation of solid-state batteries may not be widely used until the next decade. Even in the press release of Quantumscape, we can see that it has set the target of "commercial production by 2025".
