[br][br]Solid-state sodium-ion batteries are far safer than lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers Friday reported developing an organic cathode that dramatically improves both stability and energy density.[br][br][strong]Difference between Solid State Battery and Another Type battery's:-[/strong][br][br]The big difference between solid-state batteries and other types of batteries is the use of solid electrolytes, rather than the liquid electrolytes used in other batteries. Lithium-ion batteries have seen technological advances, but experts widely believe that lithium-ion technology has reached the limits of its efficiency. The next step into the future requires a different type of battery, and that’s where solid-state batteries come into the picture.[br][br]

[br][br]Solid-state batteries are smaller, lighter, and provide greater power density than lithium-ion batteries based on liquid electrolytes. The main challenge to their widespread adoption has been the search for a solid electrolyte with sufficient conductive capacity for large batteries, as well as a manufacturing method that allows for economies of scale.[br][br][strong]What does solid-state mean?[/strong][br][br]The battery in your phone or camera is likely lithium-ion, which is light, charges quickly and rechargeable. It’s made up of solid lithium electrodes set in a chemical electrolyte. Solid-state batteries ditch that liquid electrolyte in favour of a solid conductive material such as a polymer or ceramic. [br][br]Advantages:-[br][br]Solid-state battery technology is believed to be capable of higher energy density (2.5x),because of their tolerance to higher temperatures, avoiding the use of materials in current batteries that may be dangerous or toxic.[br][br]Because most liquid electrolytes are considered to be flammable, solid-state batteries are believed to be safer. As fewer safety systems are needed, a more compact battery is possible, improving energy and power densities.[br][br]

[br][br]Solid-state battery technology is also believed to allow for faster recharging for electric cars.In addition, higher voltage and longer cycle life is possible with solid-state batteries.[br][br][strong]Disadvanteg:-[/strong][br][br][strong]Cost:-[/strong]Solid-state batteries are traditionally expensive to makeand current manufacturing processes are noted to be immune to economies of scale. It was estimated in 2012 that, based on then-current technology, a 20 Ah solid-state battery cell would cost US$100,000, and a high-range electric car would require 800 to 1,000 of such cells.Cost is noted to be a factor that has impeded the adoption of solid-state batteries in certain areas, such as smartphones.[br][br][strong]Temperature and Pressure impacts:-[/strong][br][br]In addition, low temperature operations may be challengingand solid-state batteries were once noted for having very poor performance, making their use in rechargeable batteries impractical.[br][br]

[br][br]Meanwhile, solid-state batteries with ceramicelectrolytes require high pressure to maintain contact with the electrodes.Solid-state batteries with ceramic separators may break from mechanical stress due to their rigid nature.[br][br][strong]Counslation:-[/strong][br][br]Clearly there is still a lot of ongoing research into solid-state battery technology. We’re not going to see mature cells make their way into consumer products like smartphones for another 4 or 5 years, according to the earliest predictions. Solid-state batteries in other devices (like drones) may appear as soon as next year though.[br][br]Still, the latest research is finally producing results that can compete with existing li-ion batteries in terms of attributes, while also providing the benefits of solid-state electrolytes. All we need is for manufacturing processes to mature, and there are a number of large and upcoming battery manufacturers with the resources to make this a reality.[br][br][strong]Source's--( [/strong][a href="https://www.androidauthority.com/lithium-ion-vs-solid-state-battery-726142/"]1[/a][strong] [/strong][strong])--( [/strong][a href="https://en.m.wikipedia.org/wiki/Solid-state_battery"]2[/a][strong] [/strong][strong])--( [/strong][a href="https://www.google.com/amp/s/www.maketecheasier.com/solid-state-batteries/%3famp"]3[/a][strong] [/strong][strong])[/strong]
