What is a “solid-state” battery?

There are many misconceptions of what “solid-state” actually means. Yoshino adheres to the commonly accepted scientific definition that a solid-state battery is one that uses a solid electrolyte in place of liquid or gel electrolyte found in traditional lithium batteries.

What kind of battery does Yoshino use?
Poster

Yoshino’s power stations all use Lithium-NCM batteries with an Inorganic Polymer Composite electrolyte that is recognized by the scientific community as “solid-state”. Yoshino is the only company offering commercially available power stations that fit this description.

Are solid-state batteries safer than conventional lithium batteries?

Yes

Generally, solid-state batteries have a much lower risk of catching fire, short-circuiting, or being adversely affected by extreme temperatures.

 

Specifically, Yoshino’s batteries have been tested by respected third-party, US-based laboratory Energy Assurance in the following ways:

Nail Penetration Test

Thermal Abuse Test

Short Circuit Test

Are Yoshino batteries 100% flame proof?

No battery is 100% flame proof. Any battery can catch fire under violent treatment, for example if the anodes and cathodes are pressed together. But Yoshino’s batteries, and solid-state batteries in general, have very high thermal stability and are much less likely to catch fire or explode.

Is there any liquid in Yoshino batteries?

At the current state of solid-state technology, no mass-produced battery is completely liquid free. Some residual binding fluid, composing less than 5-10% of the total battery’s volume, remains as a result of the manufacturing process.

Are solid-state batteries lighter than conventional lithium batteries?

Solid-state batteries can achieve an energy density up to 2.5x higher than conventional batteries. This means that more power can fit into a lighter, smaller package.

What’s next for Yoshino’s batteries?

We are constantly innovating and building on our established success in battery technology. Currently, Yoshino offers the only commercially-available solid-state battery power stations. With current technology, this is the only way to bring affordable and accessible solid-state batteries to consumers everywhere.

Future generations of Yoshino products aim to achieve up to 3x energy density compare to LFP batteries, bring new levels of solid-state stability, and consistently lower prices.
