Divulging Solid-State Battery TechnologyPosted by Thomas Kakin on January 15th, 2025
The constraints of corrosion, solvent consumption, and passivation in Liquid-state batteries inspired the idea of developing solid-state battery technology. Solid-state battery (SSB) dispenses with liquid electrolytes and avoids gassing or liquid leakage. These batteries require solid electrolytes that are yet to be found in conductivities comparable to aqueous solutions. The solid-state electrolytes (SEs) in solid state battery technology offer more safety compared to the existing liquid Li-ion technology. One of the most promising applications of solid-state Ionics is a solid-state battery that provides high energy or high-power density energy storage with amplified safety and temperature stability. Solid electrolytes are the only components that help in identifying solid-state batteries and SEs with good conductivity of ions. Technologies Underpinning Solid-State Battery The designing of solid-state batteries underlies various technologies, solid electrolytes, and electrodes being the two major tech components. Below are the underlying technologies of solid-state batteries:
Characteristics of Solid-State Batteries Solid-state battery technology has transformed the electronic vehicle and energy storage industries, with batteries having multiple features. Here are some characteristics of a solid-state battery- 1) Non-flammability: The solid electrolytes in these batteries are non-inflammable. It offers solutions to safety concerns and environmental compatibility. 2) Longevity: Solid-state batteries last longer compared to liquid-state ones as they undergo less tear and wear during operation. They are shock and vibration-proof and can operate within temperatures up to 200 ° Celsius. 3) Safety and High energy density: This battery type provides safety, achievable energy density, and longevity. The solid electrolytes simplify cell structure and remove restrictions in terms of architecture and safety. 4) Flexibility and lightweight: The solid-state battery technology makes sure batteries are flexible and lightweight, making them suitable for electric vehicles, medical devices, and military facilities. Advantages Solid-state batteries are considered more effective than lithium-ion alternatives. Below are key advantages offered by solid-state batteries across various applications. 1. Improved Energy Density Thanks to solid-state battery technology, the production of lithium batteries has been revolutionized with solid-state batteries. A solid-state battery has a high energy density that allows more energy storage per unit volume or weight. 2. Faster Charging Compared to lithium-ion batteries that take up to 12 hours to charge, solid-state batteries can take a maximum of 15 minutes to complete 80% charge. These batteries can be charged 5 times more than lithium-ion batteries throughout their lifecycle. 3. Increased Safety and Thermal Stability The solid electrolytes are non-inflammable, which increases safety. The chemically and thermally stable electrolytes increase the thermal stability of these batteries. 4. Reduced Risk of Leakage or Explosion Unlike liquid-state batteries, a solid-state battery relies on solid electrolytes. This prevents leakage of liquid components and chances of explosion. 5. Expanded Temperature Solid-state batteries are temperature tolerant. They can work at extreme temperatures and also avoid overheating. 6. Longer Lifecycle As this battery type has a higher energy density, they are likely to have a longer battery life. Their longer lifecycle withstands charging cycles without degrading the lifespan. 7. Enhanced Performance With faster charging, expanded temperature, high energy density, and reduced leakage, the solid-state battery technology enhances the performance of devices using this battery type. 8. Lowered Cost A solid-state battery has a comparatively lower cost than a lithium-ion battery as it eliminates anode host material and reduces manufacturing costs. 9. Lower Carbon Footprint As it requires fewer materials at the time of manufacturing, a solid-state battery reduces environmental impact significantly. Disadvantages Despite a wide range of benefits, solid-state battery technology has many disadvantages as well.
Examples of Solid-State Battery Application Solid-state batteries are applied on a range of devices. Let’s have a look.
Conclusion A solid state battery faces challenges in implementation and scale-up. However, this battery design intends to take a step further in devising a more efficient and advanced battery using a “pouch cell” design. With advancements in solid-state technology, we are yet to witness the unformidable power of solid-state batteries in the near future. Like it? Share it!More by this author |
