Limited by the technical level of power lithium-ion battery, new energy vehicles have low range, short life (low charging and discharging times) and high attenuation rate, which hinder the large-scale application of new energy vehicles. Recently, South Korea and Japan have announced breakthroughs in power lithium-ion battery material technology, and the cost of power lithium-ion battery will decrease in the future. South Korea: Power lithium-ion battery capacity increased by 45% Information from the online ed
