Power banks have become a must-have gadget, often making it difficult to function without them. However, the problem with ordinary lithium-ion power banks is that they can explode or even catch fire if they malfunction. However, technology has now advanced beyond power banks. These are called solid-state power banks, which have been launched in the market by companies like SolidSafe and Kuxia.
This technology can make charging devices with power banks much safer. It is claimed that even a knife pierced through a solid-state power bank will not explode. However, the situation with lithium-ion power banks is quite the opposite.
Everyone touts solid-state power banks as superior and safer than traditional lithium-ion batteries. This is because lithium-ion batteries use liquid or gel electrolytes, which can catch fire when heated. Solid-state power banks are made using solid materials such as ceramic, sulfide, or polymer.
Compared to a conventional power bank, a solid-state power bank offers several advantages. For example, it is more secure against the risk of fire or explosion. According to one report, even a knife stabbed through it did not explode. Instead of fire, it emitted only a small amount of smoke.
These batteries also have a longer lifespan. They don’t suffer from battery swelling and can last for years without failing.
One of their strengths is their excellent battery life. Even a small power bank can provide long-term backup.
Solid-state power banks can charge faster than any conventional lithium-ion battery power bank.
Solid-state power banks are safer but also more costly. Because of their new technology, their prices are currently higher. According to a report, SolidSafe’s 5,000 mAh wireless power bank model is available for approximately $59.99, or approximately Rs. 5,000, while its 10,000 mAh model is priced at $79.99.
On the other hand, a standard power bank is available for half the price and twice the capacity. Therefore, this technology is currently for those who want a safe power bank, not a cheap one.
It’s worth noting that despite its many advantages, solid-state power banks are not without drawbacks. While these power banks may not explode, dendrites are a major problem. Dendrites refer to small cracks that appear within the battery. When these batteries are charged rapidly, these cracks widen, weakening the electrolytes. This is why scientists are working on better materials for their production.
