Which is better, lead acid or lithium battery

　　The new national standard for electric vehicles will be officially implemented in less than a month. The new national standard is a new challenge and a new journey for the industry.

　　As the power source of electric vehicles, batteries are as important as human hearts, and their safety issues cannot be ignored. One pile of electric vehicle fire accidents is alarming. The root cause is that most batteries are the first to catch fire.

　　The new national standard has put forward higher requirements for the safety of electric vehicles. The vehicle mass is not more than 55KG (including batteries), and the battery voltage is 48V, which also shows that the future electric vehicle batteries are mainly low voltage and light weight. Traditional lead-acid batteries no longer meet the requirements of the new national standard. In the coming era of the new national standard, lithium batteries will replace lead-acid batteries.

　　For ordinary lead-acid batteries on the market, lithium batteries have the following ten advantages: long cycle life, good low temperature discharge performance, strong charge retention ability, strong continuity ability, high energy, wide operating temperature range, short charging time, high green environmental protection performance, large current discharge, and large current discharge does not affect the life. When selecting lithium batteries, you should also be extremely careful. Only large quantities of lithium batteries that have passed multiple life cycles and have been tested and verified by the market for a long time are the most safe and reliable.

　　At this year's Taizhou Electric Vehicle Exhibition, many auto enterprises released their new national standard models. In terms of batteries, without exception, lithium batteries are used to replace traditional lead-acid batteries. It is not difficult to see that in the era of new national standards, lithium electrification of electric vehicle batteries is imperative.

　　At the same time, with the rise of lead price, the cost of lithium battery has dropped significantly compared with the price of lead acid, but its performance has more advantages than that of lead acid. Driven by the requirements of the new national standard and cost advantages, the lithium battery will become the market leader, and the lithium battery electric vehicle will usher in a big explosion. We boldly predict that the annual output of lithium battery electric vehicles will exceed 10 million in 2019.
