Energy and time

Алюминий-ионный аккумулятор

I welcome everyone who is interested in energy and time!

As a follow-up to the previous materials on “FREENERGY”, I would like to present you a very interesting invention made by Stanford University scientists. New aluminum-ion battery.

       “We have developed a rechargeable aluminium battery which can replace the existing energy storage devices, such as alkaline batteries which are harmful for the environment, and lithium-ion batteries which can burst into flames occasionally.” says Hongjie Dai, a professor of chemistry at Stanford. “Our new battery won’t catch fire even if you drill through it

The following features have especially drawn my attention:

  • 7500 complete charge-discharge cycles durability instead of existing 1000 cycles
  • the ability to be fully recharged in 60 seconds
  • flexibility, light weight, and, most important, battery structure endurance
  • safety, obviously

I think that the above-mentioned characteristics will open up interesting possibilities for development and improvement of consumer qualities in FREENERGY facade system.

So, sorting it out:

  • 7500 charge-discharge battery cycles mean that there will be needed 2 complete cycles per day in 10 years usage of FREENERGY facade system. Something which is absolutely unnecessary. According to our calculations, the battery will be undergoing a full charge-discharge cycle no more than once in five days.
  • Fast rechargeability means possibility of using the battery in all the climate zones found on Earth. The length of a solar day and solar activity vary in different parts of the Earth. For example, in Spain there could be an average of 300 sunny days per year, and the temperatures could surpass 40ºC degrees. On the contrary, in Saint Petersburgh there are about 80 sunny days a year and the weather isn’t hot at all. In Novosibirsk, though, despite of 40ºC degrees below zero, the number of sunny days a year amounts to 200. With such batteries used as components, FREENERGY facade system will be suitable for implementing in all types of climate zones of the Earth.
  • flexibility, light weight and structure endurance are positive features of the presented batteries. Their use will permit to replace metal reinforcement in facade and window systems.

Reinforcing profile

 

Replacing metal reinforcement with batteries in FREENERGY facade system will permit the use of more space for energy storage. The window system will become more durable, more compact and lighter.

  • finally, the safety. What can be more important than safety when it comes to the structure of systems, installed in our house, in our office, at work or in a holiday hotel?

Let us wish the scientists and engineers from Stanford successful results in their study. We will be looking forward to the launch of commercial production of the new aluminium-ion batteries to use them in our FREENERGY project.
