1. Exceptional Battery Capacity

1.1 High – Capacity Anodes and Cathodes

CNS BATTERY’s lithium – sulfur batteries feature sulfur – based cathodes, which have a theoretical specific capacity of up to 1675 mAh/g. This is significantly higher than the specific capacity of traditional lithium – ion battery cathodes, such as lithium – cobalt – oxide (LiCoO2) with a specific capacity of around 140 – 160 mAh/g. The high – capacity sulfur cathodes in our lithium – sulfur batteries enable them to store more charge, providing longer – lasting power for various applications. You can find more details about the sulfur – cathode technology on our solutions page.

Paired with the sulfur cathodes are lithium metal anodes. Lithium metal has the highest theoretical specific capacity (3860 mAh/g) among all anode materials. The combination of lithium metal anodes and sulfur cathodes in our lithium – sulfur batteries results in a battery with an overall high capacity. This high – capacity design is especially beneficial for applications that require long – range operation, such as electric vehicles and long – duration energy – storage systems. You can discuss the anode – cathode combination and its impact on capacity with our business director, Amy, at amy@cnsbattery.com.

1.2 Capacity Retention over Time

One of the challenges with lithium – sulfur batteries has been capacity fade over time. However, CNS BATTERY has developed advanced electrolyte formulations to address this issue. Our electrolytes are designed to minimize the polysulfide shuttle effect, which is a major cause of capacity degradation in lithium – sulfur batteries. By reducing the polysulfide shuttle, our lithium – sulfur batteries can maintain a high capacity over multiple charge – discharge cycles. You can find more information about our electrolyte – related capacity – retention improvements on our solutions page.

We also use nanostructured materials in our lithium – sulfur batteries to enhance capacity retention. These nanostructured materials, such as carbon – sulfur composites, provide better confinement of sulfur and lithium polysulfides, reducing their loss during cycling. As a result, our lithium – sulfur batteries can retain a significant portion of their initial capacity even after hundreds of charge – discharge cycles.

2. High Energy Density

2.1 Lightweight and Compact Design

Lithium – sulfur batteries from CNS BATTERY are designed with low – density components. The use of sulfur, which is relatively lightweight, and lithium metal in the electrodes contributes to a lower overall battery weight. Compared to traditional lithium – ion batteries with heavier electrode materials, our lithium – sulfur batteries can achieve a higher energy – to – weight ratio. This makes them ideal for applications where weight is a critical factor, such as in aerospace and unmanned aerial vehicles (UAVs). You can find more details about the weight – energy – density relationship of our lithium – sulfur batteries on our solutions page.

In addition to lightweight components, we have optimized the cell structure of our lithium – sulfur batteries. Through advanced manufacturing techniques and innovative cell – design concepts, we have reduced the volume occupied by non – active components within the battery cell. This results in a more compact battery design, further increasing the energy density by packing more energy into a smaller volume.

2.2 Energy – Density Comparison with Other Batteries

When compared to traditional lithium – ion batteries, CNS BATTERY’s lithium – sulfur batteries offer a significant energy – density advantage. Our lithium – sulfur batteries can achieve an energy density of up to [X] Wh/kg, which is [X]% higher than the energy density of many commercial lithium – ion batteries. This higher energy density means that for the same weight or volume, our lithium – sulfur batteries can store more energy, providing longer – lasting power.

Even when compared to other next – generation battery chemistries, our lithium – sulfur batteries hold their own in terms of energy density. For example, compared to some emerging solid – state batteries, our lithium – sulfur batteries offer a more favorable energy – density – to – cost ratio, making them a more practical and cost – effective choice for many applications.

3. Efficient Charge – Discharge Cycles

3.1 High Charge and Discharge Efficiency

CNS BATTERY’s lithium – sulfur batteries are engineered to enable fast ion and electron transfer during charging and discharging. The unique nanostructured materials and electrode – electrolyte interfaces in our batteries facilitate the rapid movement of lithium ions and electrons. This results in high charge and discharge efficiency, with our lithium – sulfur batteries achieving an efficiency of up to 90 – 95% in typical operating conditions. You can find more information about the charge – discharge efficiency mechanisms on our solutions page.

We have also taken measures to reduce the internal resistance of our lithium – sulfur batteries. By using high – conductivity materials and optimizing the cell – assembly process, we have minimized the resistance within the battery, which in turn reduces energy losses during charging and discharging. This low – internal – resistance design contributes to the high charge – discharge efficiency of our lithium – sulfur batteries. You can contact our business director, Amy, at amy@cnsbattery.com to learn more about the internal – resistance – reduction techniques.

3.2 Quick Charging Capability

In addition to high charge – discharge efficiency, our lithium – sulfur batteries support quick charging. We have developed advanced charging algorithms that are tailored to the unique electrochemical properties of lithium – sulfur batteries. These algorithms can optimize the charging process, allowing our batteries to be charged to a high state – of – charge in a relatively short time. For example, our lithium – sulfur batteries can be charged to 80% capacity in just [X] minutes, making them suitable for applications where quick charging is essential, such as electric vehicles.

Our lithium – sulfur batteries are also designed to be compatible with existing fast – charging infrastructure. Whether it’s a fast – charging station for electric vehicles or a quick – charging adapter for portable electronics, our lithium – sulfur batteries can take advantage of these charging systems without any compatibility issues.

4. Extended Cycle Life

4.1 Mitigating Polysulfide Shuttle and Side Reactions

As mentioned earlier, the polysulfide shuttle effect is a major challenge for lithium – sulfur batteries, leading to capacity fade and reduced cycle life. CNS BATTERY has developed polysulfide – trapping materials that can effectively capture and retain lithium polysulfides within the battery. These materials, such as metal – organic frameworks (MOFs) and functionalized carbon materials, prevent the loss of active materials and reduce side reactions, thereby extending the cycle life of our lithium – sulfur batteries. You can find more details about our polysulfide – trapping materials on our solutions page.

We have also focused on promoting the formation of a stable solid – electrolyte interphase (SEI) on the lithium metal anode. A stable SEI can protect the anode from continuous corrosion and side reactions during cycling. Through the use of special electrolyte additives and optimized charging – discharging conditions, we have been able to form a robust and stable SEI, which contributes to the extended cycle life of our lithium – sulfur batteries.

4.2 Cycle – Life Performance in Real – World Applications

Our lithium – sulfur batteries have undergone extensive long – term testing in various real – world applications. In electric – vehicle simulations, our batteries have demonstrated the ability to maintain a high capacity and performance over thousands of charge – discharge cycles. For example, in a typical electric – vehicle usage scenario, our lithium – sulfur batteries can achieve over 1000 cycles with a capacity retention of more than 80%. You can find the long – term testing data on our solutions page.

Our lithium – sulfur batteries also show excellent reliability in different environmental conditions. Whether it’s in high – temperature or low – temperature environments, our batteries can maintain their cycle – life performance. This makes them suitable for a wide range of applications, from tropical regions to cold – climate areas.
