Akkumulatoren in der Zukunft?

xVeithByxVeith

Was kommt demnächst auf den Markt/was fehlt noch? Was würde Akkumulatoren in der Zukunft verbessern?

(nachhaltiger, günstiger etc.)

Auch in Hinsicht auf Elektroautos z.B. austauschbarer Akku an Tankstellen oder so

LED Birnen GU10 blinken alle 5 Minuten. Sind über Dimmer betrieben. Was kann das sein?

ByMarkusR88

Ich habe ein Problem mit unserer Tischbeleuchtung. Es sind 8 LED Birnen GU10 welche über einen Dimmer betrieben werden. Der Dimmer ist sowohl für LED als auch herkömmliche Glühbirnen da die Beleuchtung noch eine Ambientefunktion hat auf die man umschalten kann. Sind noch herkömmliche Glühbirnen. Seit Anfang an blinken die LEDs alle 5 Minuten. Sie…

Handy Gefahrgut?

ByKuumakoi

Hab mein altes Smartphone via eBay Kleinanzeigen verkauft und will’s morgen versenden. Gilt das als Gefahrgut oder wie läuft das? Hab das jetzt wie auf dem Bild zu sehen verpackt. Bring ich das jetzt einfach zu DHL und die Kennzeichnung auf dem Karton genügt? Extrakosten? Wie sieht’s aus? Danke im voraus.

I do not expect a revolution in battery technology in the coming years. Rather, it is to be expected that many small inventions make the batteries always “better”.

The batteries will increase in energy density and decrease from internal resistance. In addition, the cyclic strength will increase further and the temperature dependence will decrease.

The battery packs thus become smaller and more durable and the quick-adjustability also increases.

Electric cars will also benefit from model generation to model generation.

I don’t believe in battery exchange. Manufacturers who rely on Tauschakkus would have the considerable disadvantage that they would have to keep the batteries compatible for a long time. Competitors without Tauschakkus could therefore implement innovations more quickly and thus possibly score with the customer.

I can’t answer what’s going on soon, but what the broad mass needs especially for e-mobility (in terms of broad mass suitability):

  • High energy density
  • significantly lower degradation of the batteries, especially at high charging and discharging currents and temperatures
  • significantly improved charging times
  • reduced resource consumption in the production of batteries (which is often neglected in environmental accounting)
  • continuous cost optimization during production
  • More efficient recycling processes

To cope with all this, you need a lot of science and engineering work, but also the necessary electrical infrastructure for mass suitability

  • solid network construction, i.e. exorbitant high cable laying and civil engineering
  • increased demand for transformers and local network stations with high power low voltage transformers

and the most important

Clean energy recovery.

The sum of this is that the whole issue will take decades.

I no longer expect a quantum leap in the development of electrochemical batteries. I also see no sense of investing in the cycle strength or fast charging capability, etc. It’s unnecessary. Because:
I am convinced that the batterylogistics must change and becomes:
Batteries will no longer be installed fixedly with the vehicle and will no longer belong to the car owner. This is how “thanking” is revolutionized:
you drive to a station, and a machine exchanges the empty for a full battery, and it goes on.
Of course, age and state of charge are taken into account every time, you pay a rent and of course the spent energy. A logistics financed with the rent ensures that defective batteries are removed from the cycle and always new ones are added.
