The accutechniek of electric cars is, according to professor Andrew Hintennach, who works at a Mercedes-Benz, is still in its infancy. Not only do we have a lot of stretch in the current technology, the battery technology of the future, it also offers a host of features. For a brief overview.
The current situation is clear: lithium-ion batteries have been the standard for use in electronic devices and electric vehicles. That might eventually be repaid by the accupakketten with the so-called vastestofbatterijcellen. Also, are there any evolutions that could conceivably be of the lithium-ion batteries.
"In the next few years will be lithium-ion in the world. Of course, we are working hard on innovation and the use of alternatives to the "post-lithium-iontijd'. In addition, attention will be paid not the least, to have a greater energy density and faster charging. We can learn a lot about the use of alternative materials and celchemie," said Hintennach.
in Addition to a lengthy life of the battery is capable of recycling high on the list. That is, it is also of vital importance, as we have here in Europe, hardly any primary sources. Reduction of the materials used in the manufacturing is according to the Hintennach is crucial.
"I think we want to be in five to ten years should be enough used voertuigbatterijen available for cobalt, nickel, copper, and, later, also of the silicon on an industrial scale and for recycling. We now have our own testaccucellen. We are going to go up 99 percent, re-use, and it is now working on the recovery of lithium out of the cells to do so."

The other is a revolution in the accutechniek for many years, on top of the market, is the solid-state battery. There is a lot of that to be expected, but still, the euphoria is, according to Hintennach, but at least partly justified.
"It is a much safer and simpler solution. What do you mean, safer? As opposed to the liquid electrolyte and, as of now, is non-flammable," says Hintennach. In fact, it is the technology that is already available. Toyota, it would be this summer at the Olympic Games in Tokyo has been in a vehicle with a solid-state battery, deploy, and Mercedes will be the Citaro bus later this year on this technology.
For a step-by-step application in a passenger car, it is still a long way to go. That is very different than the predictable pattern of a bus is about Hintennach. "In a large bus, and especially the coaches, there is the added benefit that you have a lot of space available to you. Another advantage is that their battery life is very good, as they are so used to. Very fast loading it is a problem, however, is that personenwagentoepassing, therefore, is a stumbling-block."
Sulfur is very good for the durability of
The other great things that are coming up, it could be summed up as the work of the two 'poles'. Call it an evolution of the existing lithium-ion technology. This is what happens at the anode and cathode sides, between which the lithium ions are 'moving' during loading and unloading. If you are driving, the Li+ions from the anodezijde the kathodezijde. On the charger, the opposite is true.
"A major project has been the replacement of graphite in the anodekant of the cells is silicon. You can't be in the next few years to see it happen and it will mean a big step, as it will allow us to be the energy density by 20 to 25 percent. It also allows for a very fast-loading as possible," said Hintennach.
Silicon, then opens doors that are now closed, to fill the researchtopman it. A number of promising 'materials' does not, with the currently used graphite and combinations.
Manganese is, for example, has the full attention of, a material that has, for many years, used in non-rechargeable batteries be used. A while later, it is the lithium-sulfur as a possible alternative, but it is not within the next ten years, a major breakthrough is expected. That last one is, nevertheless, often quoted, because sulphur is widely available and almost as a by-product.
Hintennach: "If you have a nickel, and cobalt in the battery cells now can be replaced by sulfur, to enhance the sustainability, are huge. It also has great potential for enhancing the energy density, so you have about a 1000 miles you can drive. In practice, you will have to make the smaller accupakketten that you can download. The drawback is, for now, is that life is too short."
