The rapid advancements in energy storage technology has sparked a revolution in how we store and consume that energy. Graphene supercapacitors are no exception. They have emerged as a better product as compared to the lithium-ion batteries. Encap batteries are presented by Emtel Energy as a global partner, have collection of products with energy storage like Enwall, Ensega, Enlight, Micro Econo 7.1kWh and Baterrix that have significantly improved features than a lithium-ion battery:
- Energy Density of Encap Batteries by Emtel Energy is up to 460Wh/kg
- More than 99.1% round trip efficiency
- 100% (Depth of Discharge) DOD
- No Degradation of Cells, no thermal runaways, Fast Charging.
- No chemical reaction during charging or discharging
- Low Maintenance Required
- 500,000 lifecycles, meanwhile lithium batteries have 6000 life cycles.
- No Environmental impact with 100% recyclable material.
1. Energy Density of Encap Batteries by Emtel Energy is up to 460Wh/kg
In 2022, A prototype was formed that could store energy up to 350Wh/kg. However, in Q1 of 2023, a Mobility storage battery for electric vehicles by the name “Batterix” was tested to store 460Wh/kg energy using graphite ion-based capacitor cell which is a significant improvement from the previous models. The same year, Encap was launched which had the highest energy storage for stationary applications using the encapsulated capacitor cell. The lithium batteries have 200-300 Wh/kg of energy density.
2. More than 99.1% round trip efficiency and works under -30°C to +65°C.
Encap Batteries have 99.1% round trip efficiency and can work with ease in extremely low (-30°C)to extremely high temperatures (+65°C). However, Lithium Batteries have 80-90% round trip efficiency and exposure to higher temperatures might make the lithium battery unstable.
3. 100% (Depth of Discharge) DOD
The depth of discharge of a supercapacitor battery by Emtel Energy offers 100% Depth of Discharge.
4. No Degradation of Cells, no thermal runaways, Fast Charging
No degradation in the Encap supercapacitor battery due to the full charging and discharge. Since no chemical process is taking place, the batteries do not degrade. This is not the case with Lithium-Ion batteries. Lithium batteries have a shorter life, they degrade, and comparable fast charging is next to impossible because of many factors like rising temperatures, degradation issues in lithium-ion batteries, and risk of thermal runaways
5. No chemical reaction during charging or discharging
No chemical electrolyte is present. No chemical reaction during charge and discharge. However, Chemical batteries like lithium-ion batteries have chemical electrolytes present, and chemical reactions occur during charge and discharge.
6. Low Maintenance Required
No chemical reaction, no rising temperature of the battery cells. Hence no or very low maintenance for the Encap batteries by Emtel.
7. 500,000 lifecycles, meanwhile lithium batteries have 6000 life cycles.
The lifespan of even the most advanced lithium batteries is no more than 5000-6000 life cycles. These lithium batteries have temperatures that are hard to maintain because of these temperatures, it is essential to keep them cooling at those temperatures. Otherwise, there will be degradation in the battery. Once the degradation starts, the battery will start to lose its performance.
8. No Environmental impact with 100% recyclable material
No negative environmental impact by Emtel’s supercapacitor battery because of 100% recyclable material. However, this is not the case with the lithium batteries. The production of these batteries the mining, and the deforestation it causes and extraction is well known. Moreover, Encap batteries by Emtel store Energy Electrostatically on the other hand, conventional lithium-ion batteries store energy electrochemically.
Conclusion
Encap batteries presented by Emtel Energy are far superior compared to traditional lithium-ion batteries.
