New battery to revolutionise car industry
--------------------------------------------
In 2021, Toyota intends to debut an electric vehicle, powered by a solid- state battery, able to travel 500km in one go and recharge in 10 minutes

Toyota (in collaboration with Subaru) is developing its first electric vehicle (EV), dubbed

2021: Toyota plans to introduce prototype electric vehicle powered by revolutionary solid- state battery
--------------------------------------------
2025: Solid-state battery could enter mass production
--------------------------------------------
Due: 2022

HOW SOLID-STATE BATTERY COULD BE GAME CHANGER
--------------------------------------------
Lithium-ion battery (Li-ion): Technology has reached limit of efficiency
--------------------------------------------
Solid-state battery: More powerful than Li-ion
--------------------------------------------
Battery: Charged ions travel from cathode to anode through electrolyte. Free electrons pass from anode to cathode, powering device

Electrons
Cathode (+) 
Anode (-)
Anode (-)
Cathode (+)
Ions

Solid electrolyte: Smaller and lighter than liquid or gel. Made from sodium-based material, so less harmful to environment and less likely to catch fire


Liquid or gel electrolyte: Highly flammable
--------------------------------------------
EV with solid-state battery could replace combustion engine vehicle because battery: has range of 500km per charge (more than double Li-ion fuel cell); can fully recharge in 10 minutes; can power EV for 380,000km before degrading; requires no cooling system
