These stated advantages have unsurprisingly caught the attention of not only electric vehicle (EVs) manufacturers, but also stakeholders involved in heavy road transportation and maritime travel. Solid-state battery’s downsized frame yet equal energy storage capabilities means that it effectively cuts cost while being able to increase performance and stability. Although there is still work to be done before it can be considered commercially viable, the potential it holds has led many to believe that it should and will become the standard of electrical energy storage systems within the coming decade.
Currently, lithium-ion batteries are still favored and more commonly used because of its relatively higher energy density and longer life compared to batteries made of other materials. However, as previously mentioned, the use of liquid electrolytes exposes the battery to a list of potential dangers which make it unpredictable to work with. There has always been a risk for any product that uses lithium-ion batteries whether it be toys, computers, or even EVs, as the battery’s susceptibility to high temperatures means that the it could easily overheat or spontaneously combust if the battery pack is damaged or faulty. This threat has been a major factor in prompting many researchers and battery developers to double down on their view of solid-state batteries, which are non-flammable and resistant to self-ignition, as a safer and better battery alternative for all types of technologies.
Aside from its apparent advantages in safety, researchers believe that solid-state batteries also hold the potential to store up to 2 to 3 times the amount of energy that could be stored in a liquid-electrolyte lithium ion battery of the same size. The drastic step up in storage capacity could prove to be revolutionary for EV manufacturers in addressing common reservations about EVs such as range anxiety, as using solid-state batteries will allow EVs to travel even longer distances without any changes to battery size. The ability of solid-state batteries to function under higher temperatures means that it wouldn’t require the same cooling systems needed for lithium ion batteries to keep it from overheating, hence, apart from it being a more compact battery system it is also a lighter and more efficient alternative as well.
的确，有很多理由说明从液体电池到固态电池的转变将是一个有利的变化，然而，如前所述，固态电池仍有一些障碍。 电池研究人员 have to get over in order for it to be fully implemented into practical everyday settings. One such hurdle stems from the fact that solid-state batteries feature physical limitations which are not present on lithium ion batteries. Solid-state batteries are inherently less conductive than their lithium ion counterparts because the solid medium means that it diffuses ions at a slower rate. Apart from that, the performance of solid-state batteries is thermally dependent – Solid-state batteries only operate optimally only under higher temperature conditions, while their conductivity and performance is reduced drastically under lower temperatures. This means that currently, solid-state batteries are constrained by temperatures which prevents them from being as versatile as they need to be.
