Electric vehicles have become the trend of future cars, but the battery problem is still a pain point for the industry. Most traditional electric vehicles use lead-acid batteries. Although lead-acid batteries perform well in low-temperature environments and are quite cheap, they put drivers at risk.

　　Although accidents involving human driving and gasoline vehicles often break out, the electric vehicle accident will not have much impact on the industry's wind direction. However, the use of high-density batteries may make cars more likely to catch fire or even explode. The occurrence of this incident has sounded the alarm for the electric vehicle industry, and automakers must seriously consider battery safety issues.

　　Battery capacity breakthrough and safety are the key

　　Electric vehicles have become the trend of future cars, but the battery problem is still a pain point in the industry. Most traditional electric vehicles use lead-acid batteries. Although lead-acid batteries perform well in low-temperature environments and are quite cheap, they put drivers at risk.

　　The main reason for the low price of lead-acid batteries is that they are recyclable, but this may cause some other problems. Lead poisoning incidents have been reported from time to time, and unsafe methods for recycling may further affect the health of workers. Lead is debilitating or even fatal, and strict practices may increase costs.

　　Some car manufacturers have turned to lithium-ion batteries. Although they are currently expensive, lithium-ion batteries are lighter and can store longer power, which is very suitable for electric vehicles. However, lithium-ion batteries still rely on a limited supply of rare earth metals, which may also cause worker injuries and environmental damage? Therefore, if electric vehicles will truly become popular, what we really need is a new type of battery.

　　At present, there are many alternatives to batteries, such as solid-state batteries, supercapacitor fast charging, and projects that only run on carbon and water. Venture capitalists have invested $1 billion in 2018 to advance next-generation battery technology. However, these battery concepts are not mature enough to even power products such as electric vehicles. Experts believe that advanced batteries are one of the biggest demands, and various technologies currently need breakthroughs.
