Lithium-Ion Battery
A lithium-ion battery is a rechargeable battery that operates through the intercalation and deintercalation of lithium ions between the positive and negative electrodes. It is widely used in consumer electronics, electric vehicles and energy storage systems, but carries risks of thermal runaway and fire.

Lithium-ion battery thermal runaway refers to a chain exothermic reaction inside the battery triggered by overheating, internal short circuits, or mechanical damage, causing temperature to rise sharply and potentially leading to fire or even explosion.
The core change in solid-state batteries is replacing the liquid electrolyte in traditional lithium-ion batteries with a solid electrolyte, which is non-flammable and resistant to high temperatures and can in theory improve both safety and energy density.
China holds an absolute dominant position in the lithium-ion battery industrial chain, covering upstream critical mineral processing, midstream cell manufacturing, and downstream battery pack integration

Lithium-air batteries have a theoretical energy density of up to 3,500 Wh/kg, approaching the theoretical value of gasoline.
The energy density of lithium-ion batteries increased from approximately 80 Wh/kg in the early 1990s to approximately 150–200 Wh/kg in 2007.
