With more electric vehicles on the roads, some drivers are wondering if there batteries still contribute climate change. We know these vehicles do not produce any greenhouse gases, but most people are unsure of the environmental impact of the batteries they use for EV’s.
According to the U.S. Department of Energy, electric vehicles have four main types of energy storage systems. First is the lithium-ion batteries, which are used in devices like smartphones and laptops. This battery has high efficiency, good performance at high temperatures, and most of its components can be recycled.
Nickel-metal hydride batteries are found more commonly in hybrids on the market. This type of battery has a high price, high self-discharge and low performance at higher temperatures. It is considered safer than lithium-ion because of the lack of liquid electrolytes that can spill out during crashes.
