US Army Aims High Capacity Energy Storage

Author: Source: Datetime: 2018-06-15 12:21:02
The US Army supported a new research project at the Brookhaven National Laboratory of the Department of Energy that aims to spin lithium-ion batteries to a new era of high-capacity energy storage. In addition, this means more integration of wind energy and solar power grids, considering that the US Department of Energy is currently looking for a way to save old coal and nuclear power plants from historical dustbins, which is an interesting way.

Earlier this week, CleanTechnica made a case that we are entering the nickel era, but maybe we speak too quickly. The new Brookhaven lithium-ion battery has superior performance due to the age of iron or iron trifluoride.
US Army Aims High Capacity Energy Storage
In general, when the topic shifts to energy storage and in particular increases the capacity of lithium-ion batteries, iron trifluoride generally does not pop up and there is a reason. Here is an interpreter's lab:

This compound has historically been ineffective in lithium-ion batteries due to three complications of its conversion reaction: poor energy efficiency (hysteresis), slow reaction times, and side reactions that can lead to short cycle life.

In other words, the battery is not particularly rechargeable. This sounds like a hopeless case, but on the other hand, iron trifluoride is relatively inexpensive and non-toxic. Bruker Hai’s cultural scientist and chief researcher, Enyuan Hu, offers another reason for pursuing more and better energy storage:

The materials commonly used in lithium-ion batteries are based on intercalation chemistry. This chemical reaction is very effective; however, it transfers only one electron, so the cathode capacity is limited. Some compounds, such as FeF3, can transfer multiple electrons through a more complex reaction mechanism called a conversion reaction.
