Which one is more harmful to lithium batteries or lead-acid batteries?

Lead-acid battery electrolyte is a kind of dilute sulfuric acid, which is harmful to human skin and eyes. Once contacted, rinse with clean water immediately. If it is serious, go to the hospital for diagnosis and treatment. Batteries contain heavy metals such as mercury, lead, cadmium, and nickel, and electrolyte solutions such as acids and alkalis, which are harmful to the human body and the ecological environment to varying degrees. Lithium batteries The lithium batteries we usually see are cylindrical batteries, soft-pack batteries, and square batteries, which are generally beautiful in appearance and small in size. Lithium batteries have high energy density and are often afraid to design large capacity. The energy density of lead-acid batteries is about 40Wh/kg, while lithium batteries have exceeded 150Wh/kg, and only excessive lithium batteries can be used. Once an accident occurs, firefighters and extinguishing agents cannot reach and cannot do anything. Isolate the scene in the event of an accident, and allow the accident battery to react by itself until the energy burns out. The positive lithium cobalt oxide and negative lithium-intercalated carbon materials used in mobile phone batteries are irritating once they are directly contacted or eaten by mistake. In particular, the positive electrode contains the heavy metal element cobalt, which is quite toxic. In fact, most battery systems, not just lithium batteries, need to be disassembled to see, the inside is composed of poisons, because at least one of its poles must have strong oxidizing or reducing properties. Such substances are very rare. Harmless to people. Recycling solutions The current recycling rate of lead-acid batteries is very high, almost 100% in my country; and with my country’s technological level, the pollution in the recycling process is actually very small. In addition, the current domestic lead-acid battery repair technology is relatively mature, and many users will choose to repair the battery, and prevent the recycling of the battery. And the repaired battery can reach 80% of the normal battery. Lithium battery is still a battery system with poor safety. The energy of a lithium battery is very high. Once it encounters a harsh environment, whether it is too high temperature, mechanical squeeze and puncture, or even overcharge and discharge or even short circuit, the battery is prone to overheating and even burning.
