4LR44 battery

What are the properties of 4LR44 battery? Will they replace lithium batteries?

As we all know, lithium ions are the active ingredient in mobile phones, laptops and car batteries. But given the high cost of lithium, researchers have been looking for another more abundant element to replace it.

Subsequently, some startups and established companies have regarded sodium ions as the active ingredient to develop rechargeable batteries. Sodium is lithium's neighbor on the periodic table.

In addition to sodium's availability, it has several other important properties - the most important of which is its fire resistance. Of course, it can also store energy comparable to lithium-ion batteries, which is a good choice. Minah Lee, who studies 4LR44 battery at Stanford University, said.

Today, many companies are developing 4LR44 battery, with the ultimate goal of replacing lithium-ion batteries. The French National Center for Scientific Research (CNRS) recently announced the establishment of an Amiens-based startup Tiamat, which will develop and launch 4LR44 battery to the market in 2020. CNRS said it will be designed in a size model like 18650.

There is also an American startup called Aquion, which focuses on high-capacity seawater battery energy storage. Bill Gates and Kleiner Perkins initially invested $190 million in it. However, the company's subsequent development even led to bankruptcy. In July, Juline Titans LCC acquired it for $9.16 million.

Meanwhile, researchers at some universities are now focusing on replacing lithium in batteries with sodium. The advantage of scientists is that they can use large instruments (such as accelerators) to study anode materials and their functions.

We can clearly understand where the sodium actually goes, both at the delicate atomic level (how to combine with other atoms) and at a more macroscopic level and what changes occur when the electrode particles absorb sodium ions. Michael Toney, a researcher at Stanford University who is responsible for the SLAC National Accelerator Laboratory, is one of them.
