Solar Power Battery Technology Latest Developments
Batteries are my business and also one of the great failure points and replacement points in the solar power alternative energy systems that we install. The batteries have been basically the same for decades but that is about to change. Really. And that is not going towards the dangerous and more power dense lithium cells and nickel cells. No the new development for solar power batteries came from MIT development labs under a DARPA study for motive power battery system.
The new MIT battery from Chiang and his graduate students and such is a unique way of storing energy. Batteries for Solar Power need to store energy and then release it into the system. This two purpose system has always been in one system, but Chiang’s system separates these functions and then uses a black goo substance that oozes through the battery that handles the particles that contain the charges. Thus the battery innards can be changed at any time and recharged by pumping in new electrical conductive and storage material like you fill up a car.
Unlike many other battery technologies for solar power use, this battery will be able to get to market very shortly because the electrical system is easy to make and does not require dramatic alternative energy advancements or material science advancement. The system is too new to fully understand what is going on with it, but the general description shows that it takes the general contents of a battery and puts them in particle form and then places them in a plastic flowing matrix. So the cells of the battery are contained in the flowing matrix and not in firm plates of lead as standard batteries are constructed.
The future of this technology will allow for solar powered electric cars and for dramatically lower battery costs as the amount of material required to produce batteries is cut in half and the power density rises to unheard of levels as well as the replacement costs dropping. This really is the big battery news of the decade, surpassing even lithium polymer as a the hottest trend.
You may know that I am not a huge fan of lithium because of its dramatic failure modes and fire risk, but I do appreciate its power density and the advances made in charge duration. This battery will compete with lithium polymer for electric vehicles because it will offer additional benefits as well as being much safer and lower cost of ownership while reducing the complexity of the electrical systems for charging because there is no danger.
