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.

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 liquid electrolytes?

In parallel, solid electrolytes have fewer side effects than liquid electrolytes, which leads to the longer life expectancy of solid-state battery . SSEs stand out of the liquid electrolytes with extraordinary potential in increasing energy density.

What is the difference between lithium ion and solid state batteries?

This is largely due to the use of lithium metal anodes, which have a much higher charge capacity than the graphite anodes used in lithium-ion batteries. At a cell level, lithium-ion energy densities are generally below 300Wh/kg while solid-state battery energy densities are able to exceed 350 Wh/kg.

How can Niger balance its energy mix?

This transformative project, funded by the World Bank through the International Development Association (IDA), will enable Niger to better balance its energy mix, which is currently largely dominated by thermal energy. This initiative is particularly crucial for a country that frequently faces climatic shocks.

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.
