Also, some of the other batteries with silicon anodes approach the market, however, these are rather intended for Wearables, and other electronics Gadgets. Currently a handful of companies are developing anodes of these silicon-rich, the production of which is normally silicon oxide or a mixture of silicon and carbon is used. Enevate’s going on here another way. The battery manufacturer from Irvine, California, uses a specially developed porous Film, which consists mainly of pure silicon.
using the battery pack uses a new anode material
The new anode material, to its development, the founder and Chief Technology Officer Benjamin Park more than ten years, is not only cost effective, but will make according to a press release of the company’s electric vehicles possible, which will create a single charge 30 percent more range than today’s electric vehicles.

In addition, the battery could take – so the hopes of Enevate-in five minutes enough charge to ensure a range of 400 km.

Actually, the use of silicon in Lithium-ion batteries have a Problem: When Lithium-ion-batteries, the Lithium ions from the cathode to the Anode. The more ions can accommodate the Anode, the higher its energy capacity and the longer the battery can be operated. Silicon can, in theory, hold ten times more energy than the commonly used graphite. But it also extends dramatically, pulls together and falls apart after a few charging cycles easy. to be able to
Complex battery chemistry
this is a Problem to control, add to other battery manufacturers, such as Tesla, the graphite powder is currently only minor amounts of silicon. The powder is applied with a glue-like plastic, the so-called Binder, is mixed and a thin copper foil.

In this way, the Anode is manufactured. The founder and Chief Technology Officer, Enevate, Benjamin Park, sees not the solution. The Lithium-ions react first with silicon and then with the graphite. “The silicon expands still pretty strong, and the plastic binder is weak,” explains Park in the press release, and adds, that the whole of the electrode and decays with increasing amount of silicon faster.

Enevate used, however, no Binder is made of plastic. Instead, the patented process of the company creates a porous and 10 to 60 µm thick silicon film directly on a copper foil. Only a nano-meter-thick protective layer, which prevents, according to the Park”, that is, the silicon reacts with the electrolyte comes”. 2021 comes first: This is BMW’s answer to the Tesla Model 3 FOCUS Online 2021 Comes first: This is BMW’s answer to the Tesla Model 3
Recharge it in five minutes on 75 per cent
For the procedure of high-quality silicon is not even required, so that the anode cost less than their graphite counterparts, have the same capacity. And since the Material is mostly made of silicon, the Lithium-ions very quickly in and out of the slide, and thus the battery charge in five minutes at 75 percent of their capacity, without that it comes to a strong expansion.
the Park compares the technology with a theater with many seats: “If you have a full cinema, it takes a long time to find the one empty space. Here we have a movie theater with ten times more capacity. Even if we fill the cinema half, it is still not a long time to find empty places.”
