0:00 Hi everyone! Welcome back to my channel. Today I’m going to tell you about another interesting topic which is about The insane engineering of liquid metal batteries.

01:07 what is a liquid metal battery?
Researchers, Professor Donald Sadoway and Dr. David Bradwell, at MIT, have produced working prototypes of a revolutionary all-liquid metallic battery that produces a current when two dissimilar metals combine to form an alloy. Charging reverses the process of reforming the original metals. Since the metals and the electrolyte need to be in liquid form for necessary ion mobility for the reactions to take place, the battery must operate at very high temperatures. This however permits very high current densities, an order of magnitude greater than in conventional batteries, which make the liquid metal battery suitable for electrical power grid applications.

2:16 how does a liquid metal battery work:
A novel concept in reversible chemical to electrical energy storage is the liquid metal battery, in which a metal anode, metal cathode, and salt electrolyte are all in the liquid phase. The upper electrode (anode) is a low-density liquid metal selected from the electropositive, electron-donor elements and the lower electrode (cathode) is a high-density metal chosen from the electronegative, electron-acceptor elements, respectively on the left and right of the periodic table. The electrodes are coupled via a medium-density molten electrolyte, sandwiched in between, that allows metal cation transport between anode and cathode, as illustrated in the figure.

5:02 liquid metal battery vs lithium-ion?
1.The Liquid Metal Battery:
To start with, the fact that the liquid metal battery has liquid components, you will experience an extra fast transfer of chemical constituents and electrical charges within one component to the other. At the same time, this allows the rapid flow of very large current amounts in and out of the battery.
More to that, when using the liquid metal batteries, the top layer of molten tends to get thinner during discharge and thicker when it is charging. That being the case, there is no hassle involved as the battery can easily take up the container’s shape considering the fact that it is very pliable.
2.The Lithium-Ion Battery:
The lithium-ion battery happens to be an improved version of the lithium metal batteries. Although the lithium metal battery was highly effective, it had a high number of defects that lead to either bursting or burning when charging. With the introduction of other ingredients such as manganese and cobalt, the lithium metal battery was completely eliminated.

The lithium-ion battery uses a cathode that is made of lithium cobalt. The cathode is filled with an electrode that forms an ion channel in the middle. There is also a diaphragm in the lithium-ion battery that helps in the separation of the negative and positive electrodes in order to avoid short-circuiting.
Since lithium-ion batteries can be made in many shapes unlike liquid metal batteries, they can be used in a wide range of items. This includes batteries of iPhones, laptops, and cell phones. The fact that they are highly rechargeable makes them the most ideal source of power for most of the consumer electronics we have in the market today.
ambri liquid metal battery:
NEC Energy Solutions (NEC) and Ambri announced they have signed a joint development agreement (JDA) in which NEC will design and develop an energy storage system based on Ambri’s liquid metal battery technology.Ambri’s long duration cells, which are based on its patented calcium-antimony chemistry, can deliver a daily 100% depth of discharge cycling performance for over 20 years with negligible degradation at a significantly lower system cost than other battery storage technologies. Systems built with Ambri’s cells can operate safely under all environmental conditions without the need for air conditioning or fire suppression equipment – increasing the system’s efficiency while reducing project cost and maintenance.
