TLDR: Batteries play a crucial role in climate action and are key to achieving net-zero greenhouse gas emissions by 2050. They are needed for grid storage to ensure a consistent power supply from intermittent renewable energy sources like wind and solar. Additionally, batteries are essential for electrifying transportation and transitioning from gas-powered vehicles to zero-emissions electric vehicles (EVs). The versatility of battery technology is another reason to love them, as researchers are constantly developing new chemistries to meet different needs. From lithium-ion batteries to sodium-ion and zinc flow batteries, there is a wide range of options available. Finally, batteries are fascinating because they store energy through tiny ions moving inside a container, which seems a bit magical. Looking ahead, the battery industry will continue to innovate and offer a menu of battery options for various applications.
