On the morning of March 19th, Beijing time, Sila Technologies and Angstron Materials have developed a new lithium-silicon battery technology that will be available in the next few years. It can increase the battery power of mobile phones, automobiles, and smart watch batteries by 30% or more. This kind of battery can be ready for production soon.
Looking at the recent emergence of so-called 'breakthrough battery technology' is often not a big breakthrough, but Christopher Mims, a Wall Street Journal science journalist, believes that this lithium-silicon battery is a real breakthrough. BMW, Intel, Qualcomm also think so, because of this, they all provide support for the development of new batteries.
The core of the new technology lies in 'anode manufacturing', which is mainly made of silicon. The anode is the main component of the battery. The current anode of the battery is made of graphite. The new anode is made of silicon and can store more power. However, in the real world, the silicon anode is often fragile or has a short life and is difficult to popularize.
Sila Technologies has developed a prototyping product that successfully solves these problems. It fuses silicon with graphite nanoparticles to make the product more durable. Sila Technologies also said that if they use the new technology they developed, the battery stores more electricity than today. The lithium-ion battery is 20-40% higher.
Some start-ups want to develop the best lithium-silicon batteries, such as Enovix, which is backed by Intel and Qualcomm, and Enovix claims that if it uses its technology, it can increase the battery power of smartphones by up to 50%.
