Why solid-state lithium batteries are safer than regular lithium batteries?
Solid-state lithium battery is a new type of battery technology on the market. Its main feature is the use of solid electrolytes instead of liquid electrolytes in traditional lithium-ion batteries. Its structure usually includes a positive electrode, negative electrode and solid electrolyte.
Solid-state lithium batteries are considered safer than regular lithium batteries primarily due to the following reasons:
1. Elimination of Flammable Electrolytes
Traditional lithium-ion batteries use liquid electrolytes, which are flammable and can lead to thermal runaway if the battery is damaged or overheated. Solid-state batteries replace these flammable liquids with solid electrolytes, which are inherently non-flammable. This significantly reduces the risk of fires and explosions associated with traditional lithium-ion batteries.
2.Improved Stability
Solid electrolytes used in solid-state batteries are more stable chemically and thermally compared to liquid electrolytes. This stability helps in maintaining the integrity of the battery even under extreme conditions, reducing the likelihood of thermal runaway.
3. Reduced Internal Shorts
In traditional lithium-ion batteries, internal shorts caused by physical damage or defects in the separator can lead to catastrophic failure. Solid-state batteries, with their solid electrolyte and often improved internal design, are less susceptible to these internal shorts, further enhancing their safety.
4. Higher Operating Temperatures
Solid-state batteries can operate effectively at higher temperatures compared to conventional lithium-ion batteries. This ability reduces the risk of thermal runaway during high-temperature conditions, such as during charging or discharging cycles under stress.
5. Resistance to Leakage
Since solid-state batteries do not contain liquid electrolytes, they are not susceptible to leakage, which can damage devices and pose environmental hazards. This makes them more reliable for use in a wide range of applications.
Overall, the elimination of flammable liquid electrolytes and the use of stable, solid electrolytes make solid-state lithium batteries significantly safer than traditional lithium-ion batteries, addressing many of the safety concerns associated with current battery technologies.
Moreover, solid-state lithium batteries will not catch fire or explode after puncture, and can be used continuously and effectively.
