Today, with the rapid development of battery technology, we often hear news about lithium batteries, but there are few reports of lead-acid battery fires. This makes people wonder, why are lead-acid batteries safer than lithium batteries? This article will analyze from multiple aspects.
The main chemicals used in lead-acid batteries are sulfuric acid and lead, which are chemically stable at room temperature and pressure, and are not prone to violent reactions.
In contrast, lithium metal and organic electrolytes in lithium batteries are more susceptible to chemical reactions under certain conditions, which can cause fires or**.
Lead-acid batteries have a relatively low energy density, meaning that it stores relatively little energy. As a result, even in the event of an unforeseen situation, lead-acid batteries release a limited amount of energy, making it difficult to reach the energy threshold required to start a fire.
Lithium batteries have a high energy density, and in the event of a failure, the released energy may quickly accumulate and cause a fire.
Lead-acid batteries are designed with multiple safety factors in mind. For example, there are usually multiple layers of protection inside the battery to prevent short circuits and explosions inside the battery.
In addition, lead-acid batteries are equipped with safety valves and pressure relief devices, which automatically activate when the pressure inside the battery is too high, releasing the pressure and preventing the battery**.
In practical use, the maintenance and supervision of lead-acid batteries are also relatively easy. Due to the mature technology and simple operation of lead-acid batteries, it is easier for users to master the correct use and maintenance methods. In addition, the regulation of lead-acid batteries is relatively strict, which reduces the risk of fire to a certain extent.
As a relatively mature and long-established battery technology, lead-acid battery has rich production process and experience in use. In contrast, although lithium batteries are developing rapidly, there is still some room for improvement in technology and production. Therefore, the performance of lead-acid batteries in terms of safety is also relatively stable.
To sum up, the reason why lead-acid batteries are safer than lithium batteries is mainly due to the combined effect of many factors such as stable chemical properties, low energy density, reasonable structural design, restrictions on use scenarios, maintenance and supervision, and technical maturity.
Therefore, despite the advantages of lithium batteries in terms of performance and energy density, we should also pay attention to the safety of batteries while pursuing high performance, so as to ensure that battery technology can exert maximum value in applications.
