What is a solid-state battery?

A solid-state battery is an electrical battery that uses a solid electrolyte for ionic conductions between the electrodes, instead of the liquid or gel polymer electrolytes found in conventional batteries. Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries.

How does a solid state battery work?

Solid-state batteries can use metallic lithium for the anode and oxides or sulfides for the cathode, increasing energy density. The solid electrolyte acts as an ideal separator that allows only lithium ions to pass through.

Are solid-state batteries safe?

Solid-state batteries are found in pacemakers, and in RFID and wearable devices [citation needed]. Solid-state batteries are potentially safer, with higher energy densities. Challenges to widespread adoption include energy and power density, durability, material costs, sensitivity, and stability.

Are solid-state batteries better than lithium ion batteries?

Solid-state batteries theoretically offer much higher energy density than the typical lithium-ion or lithium polymer batteries. While solid electrolytes were first discovered in the 19th century, several problems prevented widespread application.

What are the characteristics of a solid-state battery?

This kind of solid-state battery demonstrated a high current density up to 5 mA cm −2, a wide range of working temperature (-20 °C and 80 °C), and areal capacity (for the anode) of up to 11 mAh cm −2 (2,890 mAh/g).

Where can I find a report on solid state batteries?
