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.

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.

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.

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.

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.

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.
