In the battery used by mobile phones, laptops and other electronic products, there will be similar situations in every 500 to 1 million batteries - which means the possibility of fire. "Although this is a small probability event, once the consequences will be catastrophic.Although the lithium-ion battery is currently the internationally recognized ideal chemical energy, the lithium-ion battery is interested in energy density, cycle life, environmental protection, but has fatal in terms of industrialization. shortcoming. Various damage to short circuits or internals may result in overheating of the latest generation of lithium batteries, which in the electronic products may have disastrous consequences for electric vehicles.
In terms of cost performance, lithium batteries are far less than lead-acid batteries. In the field of battery, lead-acid battery advantage is obvious: technology maturation, stable performance, cheap, and high cost performance. In 2005, the annual sales of global lead-acid batteries were $ 24.7 billion, and the annual output of US $ 10.5 billion, accounting for 1/3 of global production. In Japan, the industry's employees of lead-acid batteries reached several hundreds, and the annual benefits reached billions of dollars. Lead-acid batteries are now the largest battery products in the world, accounting for 50% of total battery, accounting for 70% of the charging battery, is an indispensable product in contemporary society, which is the most developed world in Europe and America. State and regions have still been produced and used in a large number of lead-acid batteries.
