Battery of the Future: How Could Solid-State Battery be a Game Changer?

Published: 30 July 2021 (6 minutes reading)

Executive Summary

• In comparison to liquid electrolyte batteries, solid-state batteries offer lower flammability, greater electrochemical stability, higher potential cathodes, and higher energy density.

• For electronic gadget industry – you will see a smaller and lighter gadget in any gadgets you can think of, as previously, battery is very large and occupy most of the space in the in the gadget

• For EV industry – a 500 km range on a single charge, as well as a fast recharge from zero to full in just 10 minutes!

Solid-state batteries have been around for quite some time with research beginning in the early 90s. However, a major breakthrough came in 2015 when researchers from the University of California Irvine, published a paper detailing their solid-state battery design. In this paper, they stated that this design was capable of producing double the energy density of lithium-ion batteries. Since then, there has been more research done on solid-state batteries; but, it is still relatively in its infancy stage and much needs to be done before we see it become mainstream and replace current lithium-ion batteries.

Benefits of Solid-State Battery

•Safety – the major advantage of solid-state batteries is, without a doubt, their greater safety. They also do not produce hydrogen gas.

•Faster Charging – solid-state batteries tend to offer much faster-charging speeds. Based on technology, some can offer 6 times faster charging than lithium-ion rechargeable batteries.

•Higher energy density – a considerable increase in energy density is another possible benefit of solid-state batteries. For some solutions, this can be as much as twice that of lithium-ion batteries for the same volume.

•Longer charge-discharge-recharge cycle life – one of the most significant advantages of solid-state batteries is their potential for longer charge-discharge-recharge cycle life. This can take up to 10 years, as opposed to the relatively modest two years for more typical options.

•Smaller size and lower down the cost – they can be (theoretically) smaller and cheaper to make and can be smaller than their equivalent Li-ion replacements.

In short, in comparison to liquid electrolyte batteries, solid-state batteries offer lower flammability, greater electrochemical stability, higher potential cathodes, and higher energy density. These qualities, together with their improved performance, might revolutionize numerous sectors that rely on battery technology.

Potential uses of solidstate batteries

Solid-state batteries will definitely be available in the near future, but as of now, they are not ready for mass production. But how will this technology transform our life? Here are some examples of possible use cases.

First possible application would be in the electronic gadget industry. The solid-state battery can shrink the battery to make more space. Today, the batteries in our devices are very large and may be the largest component of them. The battery occupies an important space that could be used for other items. Heat is one of the most common killers of devices, especially laptops. This is because there is not much space for heat to circulate. If the battery only takes up one-tenth of the original space, it will allow significantly more circulation and even make room for a better cooling system.

Another application for successful solid-state batteries will be in the EV industry. Compared to liquid batteries, solid-state batteries have the potential to reduce weight, increase reliability, range, safety, and lower charge rates. Together, these advantages will effectively revolutionize the electric vehicle industry. By 2030, sales of electric vehicles are expected to reach 32% of the total automotive market, and the need for more efficient, reliable, and durable batteries is growing rapidly. This will place a large demand on lithium resources all around the world, which is expected to drive up the cost of manufacturing new batteries in the future. And, to avoid a potential shortage of batteries, several automakers are looking for more sustainable and less expensive alternatives, such as solid-state batteries. According to Nikkei Asia article, Toyota has revealed that they want to include solid-state batteries into their new vehicles as early as this year. This may enable their EVs to provide a 500 km range on a single charge, as well as a fast recharge from zero to full in just 10 minutes.
