SEMCO (Samsung Electro-Mechanics) has developed an ultra-compact all-solid-state battery tailored for wearable devices. The innovative battery is an oxide-based small all-solid-state battery with an industry-leading energy density of 200 Wh/L.
This has achieved an equivalent level of energy density to lithium-ion batteries while being smaller in size, and SEMCO is currently promoting this product to customers through prototype evaluations. All-solid-state batteries utilize a non-flammable solid electrolyte for charging and discharging, enhancing safety and solid to external shocks, and allowing for various shapes, even at ultra-compact sizes.
