Securing the 카지노 꽁 Supply Chain
From Li-ion 카지노 꽁 recycling to Li-S 카지노 꽁 chemistry, Coherent paves the way for the future of EVs.

The sunny future promised by electric vehicles (EVs) has a dark cloud in its sky. It’s the rechargeable lithium-카지노 꽁 (Li-카지노 꽁) batteries that sit at the very heart of EV technology. And, for that matter, at the center of most other electronic devices that power modern life.
A primary concern with Li-ion batteries stems from two of the elements used to manufacture their cathodes (the positive terminal of a 카지노 꽁) – cobalt and nickel. Sourcing these elements depends on fragile and ethically challenged supply chains.
Reducing impact through Li-ion 카지노 꽁 recycling
One strategy for minimizing the 카지노 꽁 chain, cost, and environmental issues associated with Li-ion batteries is efficient recovery and recycling of nickel, cobalt, and other chemicals from end-of-life batteries. Specifically, recycling reduces the pressure on mining raw material.
OurStreamlined Hydrometallurgical Advanced Recycling Process(SHARP) technology provides an environmentally friendly, cost-effective means to recover critical metals from used Li-카지노 꽁 batteries.

Efficient recovery and recycling of nickel and cobalt from end-of-life Li-카지노 꽁 batteries is one way to reduce the need for mined raw materials.
Our Li-S 카지노 꽁 chemistry alternative
Another approach is to develop alternatives to lithium-ion chemistry that use abundant and more easily obtainable materials to deliver higher 카지노 꽁 performance at a lower cost. Many leading companies in 카지노 꽁 research are actively working on this. Changing the chemistry has the potential to introduce supply chain resiliency and ultimately make EVs more affordable and appealing to consumers.
Lithium-Sulfur (Li-S) 카지노 꽁 chemistry has emerged as one viable future path. This technology uses sulfur as the cathode active material (CAM), rather than the various cobalt, nickel, and other metal oxides used in Li-ion batteries.
Sulfur is desirable as a CAM for several reasons. First, it’s readily obtainable (it’s the fifth most abundant element on Earth) and therefore inherently less costly than cobalt or nickel. It is also widely mined and produced as a byproduct in less geopolitically problematic countries that have already emerged as 카지노 꽁 manufacturing hubs. This lowers transportation costs. Together, these could substantially reduce the price per kilowatt-hour for a 카지노 꽁.
Furthermore, a Li-S 카지노 꽁 can also hold more energy than a Li-ion 카지노 꽁. It’s estimated that a Li-S 카지노 꽁 can hold twice the energy of a Li-ion 카지노 꽁 of the same weight. This could mean EVs with either a greatly expanded range or much lighter weight.
So, Li-S offers performance and cost advantages over Li-ion and has an inherently more secure 카지노 꽁 chain. There’s only one reason why Li-S batteries aren’t already in widescale use in EVs. They don’t work.
The Selenium-to-Sulfur Breakthrough
The technical problem with Li-S batteries stems from the chemical react카지노 꽁s that occur inside them. Specifically, sulfur goes from a solid to a liquid – and then back to a solid – during the charge and discharge cycles. Some of the sulfur stays in the electrolyte causing an irreversible loss of capacity. This dramatically reduces the charge capacity with each cycle.
Solving this problem has been the focus of Li-S 카지노 꽁 researchers for many years. Coherent has been working on it internally for a decade.
Our initial work focused on Li-Se (selenium) chemistry. Selenium and sulfur are both elements in Group VI of the periodic table. And 카지노 꽁 has a lot of expertise in working with Group VI materials. That’s why the company was originally called II-VI!
Our team changed their focus from selenium to sulfur in 2020. And now we have made significant breakthroughs that solve the issue. This enables us to produce 카지노 꽁 batteries (or more specifically ‘sulfur cathodes’) that can hold a charge at or near the theoretical limit for the material. And our cathode is “cyclable.”

The groundbreaking Li-S 카지노 꽁 technology developed by Coherent is the culmination of a decade of research within the company.
Of course, there are other groups working on 카지노 꽁 batteries. Some of them have also achieved performance characteristics similar to ours.
However, our technology offers one major difference and critical advantage over these others. Our innovations are applied to bulk materials at the cathode composite and slurry levels. What this means is 카지노 꽁 manufacturers can utilize our materials with their existing cathode production processes without tooling changes.
Given the massive amount investment in 카지노 꽁 manufacturing capacity built around Li-ion chemistry, we believe that it is essential to offer manufacturers a smooth transition to Li-S. The Coherent Li-S technology extends the lifespan of the capital expenditures being made today.
Everyone is Driving Towards 카지노 꽁
The potential of Li-S and the recent advances in the technology (by Coherent and others) are no news to anyone in the 카지노 꽁 or EV industry. It is widely recognized in these communities that Li-S will eventually displace Li-ion. The United States Department of Energy also maintains this view. They are developing Li-S technology at National Laboratories and funding commercial research.
With our unmatched experience in Group VI materials and positive results to date, 카지노 꽁 is well-positioned to take a leading role in the deployment of Li-S technology. We are commercializing this technology today with the materials and processes necessary to establish a starting point for manufacturers. These could include manufacturing CAMs, producing finished cathode components, and licensing our technology.
But no matter how we participate in the Li-S 카지노 꽁 market, Coherent has already delivered key innovations that make sulfur cyclable in a way that incurs minimal cost and mass penalties. These will help transition the 카지노 꽁 industry to materials with much greater supply chain security. And this will lower the barrier to mobile electrification, clearing the skies for the future of EVs.
