In short, the solid electrolyte used in a solid-state battery provides higher energy density, longer lifespan, and increased safety in a smaller size! There are multiple benefits to solid-state battery technology. So when any device is connected to a battery, let’s say a light bulb, for example, a chemical reaction occurs between the anode, cathode, and electrolyte, creating a flow of electrical energy to power the light bulb.Ī lithium-ion battery uses a liquid electrolyte to regulate the flow of current, and a solid-state battery uses a solid electrolyte.Īnd THIS is the difference that will matter! Benefits of Solid-State Batteries The charge and discharge process of a LiFePo4 battery works by moving Lithium Ions across the electrolyte while electrons pass through the circuit. This chemical reaction permits the flow of electrical charge between the cathode and anode (through a circuit), allowing a battery to generate an electric current to power your device. The electrolyte allows lithium ions to travel through it to combine with the anode or cathode (depending on charging or discharging). These two electrodes are made of an electrically conductive material.īetween these two electrodes (and within them) is an electrolyte containing electrically charged particles (ions). While lithium-ion batteries (and most other batteries) use a liquid electrolyte, solid-state batteries use a solid electrolyte.Įvery battery has two electrodes – an anode (negative side) and a cathode (positive side). The main difference between a lithium-ion battery and a solid-state battery lies within the electrolyte. This electrolyte is a liquid in standard lithium-ion batteries.Ī solid-state battery uses a solid electrolyte to regulate the lithium ions instead of a liquid one. Lithium-ion batteries work by letting ionic lithium cross the electrolyte barrier between the battery’s anode and cathode (the positive and negative ends). One advancement that could once again change the way we store energy is the development of the solid-state battery.īefore we learn what a solid-state battery is, we need to understand how current lithium-ion technology works. Even with these advancements, however, there is potential to improve the lithium-ion battery. Enabling reliable, long-lasting energy storage for off-grid applications, lithium-ion battery technology has truly changed our world.
