Recently, the research team of IBM Research recently released information on new energy storage research, which helps accelerate the transformation of renewable energy and provides new solutions for electric vehicles and fixed batteries. According to calculations, the efficiency of new energy storage solutions is more than 90%.

Cobalt-free new energy storage technology is the key

A new energy storage announcement from IBM indicates that they hope to solve the problem of energy storage supply chain by solving the common heavy metals and other materials in lithium-ion batteries.

IBM's new energy storage research

The following is IBM's research on this topic:

Battery materials, including heavy metals such as nickel and cobalt, pose a threat to the environment and people. In particular, cobalt, a very common mineral in central Africa, is controversial because of people's negligence and exploitation in the mining process. Just a few days ago, international human rights organizations have filed a lawsuit against Apple, Alphabet, Dell, Microsoft and Tesla, accusing them of using child labor and other abuses in the cobalt mine in the Democratic Republic of the Congo.

IBM advocates "cobalt free" batteries, so what is the difference between its energy storage solutions?

First, it does not contain cobalt or nickel.

The scheme adopts three new and different patent materials. The IBM research team also found a new battery chemical component that can be extracted from seawater without using heavy metals or other substances related to the source of heavy metals. This technology is less invasive than the current material mining method.

IBM is passionate about the prospect of the battery they have developed. They think: "The performance of this new battery is as excellent as that of the materials used. In the test, its performance in many single categories has surpassed that of lithium-ion batteries, including lower cost, faster charging time, higher power and energy density.

Now let's talk about dendrites. They are hairy nanostructures formed in lithium-ion batteries for a long time. The formation of dendrites reduces the efficiency of the battery. Therefore, researchers have come up with various methods to eliminate dendrites. In the battery developed by IBM, the combination of cobalt-free and nickel-free cathode and electrolyte inhibits the growth of dendrites. In addition to solving the efficiency problem, this new battery can also reduce the flammability of the battery.

The following elements of the new battery also deserve attention:

Charging time: If configured as high power, the battery can reach 80% of its power in less than 5 minutes.

High power density: the design of the new battery is higher than 10000 W/L, surpassing the most powerful lithium-ion battery.

High energy density: its energy density exceeds 800 Wh/L, which IBM describes as "comparable to the most advanced lithium-ion battery".

Life cycle: IBM said that the new battery can be designed for a long life cycle, making it the choice of smart grid and new energy infrastructure, in which life and stability are the key.

In addition to achieving zero emissions, battery energy storage is also the golden key to help develop renewable energy resources. The United States Department of Energy is also studying a new round of battery energy storage technology to achieve sustainable development and better returns.
