Kansas City batteries are much better than conventional batteries. For example, they are safer, last longer, and charge faster.
This is because instead of a liquid electrolyte charge-conducting solution, they use a solid electrolyte. It not only minimizes the chances of fire but also enhances energy density, resulting in better efficiency. Based on these unique characteristics, rechargeable solid-state batteries can be classified into various types. They are as follows:
Classical lithium metal batteries
Lithium salt-in polymer electrolyte is typically used in lithium metal batteries. It enables Li ions to pass through easily while blocking electron movement for safety.
Hybrid solid-state battery
They replace the liquid layer in classical lithium-ion batteries with a solid electrolyte, featuring both liquid and solid-state concepts. Doing so enables them to achieve a balance between energy density and stability, making them take the best of both worlds.
All-solid-state battery
Unlike hybrid variants, lithium salt-in solid electrolytes like ceramics or glass are used in all-solid-state batteries. This further enhances safety while still offering a high energy density.
Thin film solid-state battery
The usage of Li-ion conductive materials in very thin 3 to 10 µm film formats, makes thin-film rechargeable solid-state batteries very lightweight and compact. In addition to this, their flexible nature makes them very usable in miniature gadgets like wearables and medical instruments.
Flexible solid-state batteries

They continue to complement and enhance existing technologies, especially in consumer electronics, electric vehicles, renewable energy systems, and medical devices. With ongoing research and development, these batteries will successfully replace and revolutionize traditional battery technologies in the foreseeable future.
The maintenance and repairing process for rechargeable solid-state batteries is pretty easier than for other conventional battery systems. Generally, these batteries require a few routine checks for mechanical integrity and electrolyte stability, which can be done with non-destructive techniques.
As for the repairs, they usually require the whole battery unit as they are usually designed as a compact modular system. However, advancements in repair technologies offer potential for future in-situ repair or reconditioning methods, which could significantly lower the cost of maintenance in the long run.
Lastly, the best way to maintain the structure and function of these batteries over time is to have dedicated and advanced maintenance facilities, which support the continuous operation of systems employing rechargeable solid-state batteries.
Materials
Solid electrolytes' performance and safety heavily depend on the selected material for rechargeable solid-state batteries. Generally, they use lithium-conductive ceramics or glassy solids that possess the mechanical strength and ionic conductivity needed for optimal battery functionality. Any deviation from these materials will end up impacting the overall performance and detrimentally affecting the battery's safety features.
Manufacturing Precision
These batteries require precise fabrication and assembly techniques. Thus, even the slightest inconsistency can cause the formation of internal shorts, reducing battery capacity and upward propagation of hazards. Hence, achieving high-quality solid-state battery generally hinges on a tightly controlled manufacturing process.
Testing Rigor
Testing for stability, performance, and lifecycle, among other things, needs to be comprehensive in evaluating the battery's viability. Factors like thermal stability, electrochemical performance, and aging evaluation need to be done extensively. Only then will the battery be truly fit for use in high-performance applications like electric vehicles and space tech.
Thermal Stability
Solid-state batteries are harder than their liquid electrolyte counterparts when it comes to temperature ranges. In practice, this means they can function effectively even at higher temperatures without the risk of electrolyte decomposition. However, the exact thermal limit depends on the kind of solid electrolyte employed.
Mechanical Integrity
The maintenance of the mechanical integrity of solid-state batteries is crucial in avoiding hazardous situations. More specifically, cracks or defects in the battery structure can cause a loss of conductive pathways, which explain why performing well in high-pressure environments is critical.
Sealant Durability
Solid rechargeable batteries typically integrate several materials within their design, such as flexible sealants. These components are responsible for preventing moisture and contaminants from getting into the battery's inner chamber. However, over time, these sealants degrade and fail. Therefore, mechanisms need to be put in place to enhance their durability and ensure they don't cause any danger when they fail.
