Next-generation battery research and development-Lithium - Ion Battery Equipment

Companies around the world are pouring money into research and development of next-generation batteries -Lithium - Ion Battery Equipment

According to foreign media reports, there is nothing more suitable for powering smartphones or Teslas than lithium batteries. Since its first introduction in 1991, rechargeable lithium batteries have become the common standard for powering everyday tech devices and electric vehicles. Statistics show that the vast majority of the more than 3 million electric vehicles in the world are driven by lithium batteries. But as the world moves towards the future of electricity, we obviously need better technology than lithium batteries to meet the future needs of human beings.(Lithium - Ion Battery Equipment)

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

Fortunately, some battery startups are working hard to develop better battery technology. Their ideal new battery would cost less, be more energy-dense, and perform better for industrial and consumer technology products, as well as electric vehicles that charge faster and run longer.

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

"It took eight years and about 35,000 material trials to get something commercially viable," said Gene Berdichevsky, chief executive of Sila Nanotechnology.

In fact, Sila Nanotech is just one of several battery start-ups that have all recently received significant funding to continue optimizing their battery technology. Last year, the Alameda, California-based company raised $70 million in Series D funding from investors including Siemens Global Winds to build its first commercial production line for silicon anode cells.

It should be pointed out that Bodichevsky, a mechanical and energy engineer, was Tesla's seventh employee ten years ago and was responsible for leading the design of the battery system of the Tesla Roadster model.

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

"A car needs as much material as 10,000 smartphones or 1,000 smart watches," said Burdychevsky. "We will start with consumer devices and gradually expand our cooperation with cars over the next five years." partnership."

BMW is currently one of Sila's automotive partners.

At present, lithium batteries are subject to various restrictions in terms of material composition and physical energy density. New battery technology attempts to improve the safety and energy efficiency of lithium batteries, meaning there is no risk of fire if the battery overheats or is damaged.

A new battery technology is the solid-state battery, which not only replaces the graphite anode with a lithium metal material, but also replaces the liquid electrolyte and separator with a solid piece (usually ceramic, glass or flame-retardant polymer). An industry first to adopt this approach is SolidPower, a Colorado-based manufacturer of solid-state batteries.

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

The rather mysterious Stanford spinout Quantumscape is also working with VW on a solid-state battery. Last year, Volkswagen increased its stake in the former by $100 million. The San Jose-based startup is now valued at $1.75 billion, according to PitchBook.

Media reports say Quantumscape's batteries will enable Volkswagen's E-Golf to travel 466 miles (750 kilometers) on a single charge, making it comparable to the range of conventional gasoline-powered cars. According to VW, Quantumscape's batteries will also be lighter and charge faster than existing lithium-ion batteries.
