What are the three main types of new energy vehicle batteries?
2 Answers
The three main types of new energy vehicle batteries are lithium cobalt oxide batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries. Below are specific details about new energy vehicles: 1. Definition: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and driving systems to form vehicles with advanced technical principles, new technologies, and innovative structures. 2. Types: New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.
When helping a friend research new energy vehicles last time, I found mainstream batteries mainly fall into three types. Lithium Nickel Manganese Cobalt Oxide (NMC) batteries are widely used in many premium models nowadays, like Tesla's Long Range version. Their advantages include ultra-high energy density, long driving range, fast charging, and decent winter performance. However, the nickel-cobalt-manganese materials make them more expensive, and heat dissipation needs close monitoring during aggressive driving. Lithium Iron Phosphate (LFP) batteries have gained popularity recently, becoming standard in many BYD models. Their biggest strengths are durability, non-flammability, exceptionally long lifespan, and about 30% lower cost. The downsides are faster power drain in cold weather and heavier weight compared to NMC batteries. Lastly, Lithium Cobalt Oxide (LCO) batteries were used in older Tesla models but are rare now. Despite strong performance, their poor thermal stability and high costs have made them largely replaced by the first two types. When choosing, consider your needs: opt for NMC if you prioritize range, while LFP is the safe and cost-effective choice.
