Currently, pure electric vehicles use ternary lithium batteries and lithium iron phosphate batteries. Ternary Lithium : Also known as ternary polymer lithium battery, it uses graphite material for the negative electrode and nickel-cobalt-manganese oxide (NCM) or nickel-cobalt-aluminum oxide (NCA) materials for the positive electrode. The ternary composite positive electrode material can adjust the ratio according to actual needs. Compared with lithium iron phosphate batteries, it has higher energy density, smaller battery size, and better low-temperature performance. Lithium Iron Phosphate Battery: Since lithium iron phosphate is used as the positive electrode material, it is called lithium iron phosphate battery. Its raw materials are low-cost, and the thermal control temperature of lithium iron phosphate batteries is relatively high, generally above 500 degrees. Therefore, compared with ternary lithium batteries, lithium iron phosphate batteries have relatively stronger stability. The most important advantage of lithium iron phosphate batteries is their long service life, and their charge-discharge cycle times are better than those of ternary lithium batteries.

I've been driving a pure electric vehicle for several years, commonly using lithium-ion batteries, which mainly come in two types: one is called lithium iron phosphate (LFP), and the other is ternary lithium. LFP batteries are safer and have a longer lifespan but are heavier, making them suitable for family SUVs; ternary lithium batteries have higher energy density and charge faster but are more expensive, making them popular in high-end models. These batteries are assembled into modules and placed under the vehicle, providing high energy that easily allows a range of over 400 kilometers. Nowadays, fast charging can reach 80% in just half an hour. The downside is that they degrade over time, but under normal use, they can last about eight years without major issues. In the future, solid-state batteries may offer even greater safety, and companies like CATL are actively advancing their development, which is quite exciting. For daily use, avoiding always charging to full and discharging shallowly can help extend their lifespan.

As an average car owner, I'm concerned about the practical aspects of EV batteries. Mainstream options are lithium-ion batteries like LFP (Lithium Iron Phosphate) and NCM (Nickel Cobalt Manganese). LFP batteries are affordable, stable, and require minimal , though they have slightly shorter winter range. Charging-wise, a home charger fills it overnight, while fast chargers restore half capacity in 20 minutes - significantly cheaper than gas. Battery lifespan degrades with use and temperature; keeping charge between 20%-80% minimizes wear. Replacement costs tens of thousands if aging occurs, but warranties typically cover 8 years or 200,000 km. Just monitor battery health via app occasionally - very hassle-free.

I focus on the environmental perspective regarding the issues of pure electric vehicle batteries. Currently, lithium-ion batteries such as ternary or lithium iron phosphate types are widely used. While they reduce tailpipe emissions, the extraction processes for resources like lithium and cobalt have environmental impacts. Fortunately, advancements in recycling technology enable the reuse of up to 90% of materials, with projects like Tesla's being quite reliable. The future trend leans toward solid-state batteries, which are more eco-friendly, use fewer rare earth elements, and are safer. Although current batteries offer fast charging and support the energy transition, ecological balance must still be considered. Using energy-saving modes while driving can extend life and reduce waste.

With years of experience in car repair, I've handled numerous pure EV cases. The industry predominantly uses lithium-ion batteries, mainly lithium iron phosphate, which are cost-effective and durable but require careful maintenance to prevent circuit overheating. When batteries age, capacity drops rapidly—early diagnosis via health monitoring apps is crucial. Replacement costs ranging from 30,000 to 50,000 yuan are steep but often covered by insurance. Beginners should avoid deep discharges or prolonged high-temperature exposure to protect battery pack lifespan. Emerging technologies like high-nickel batteries offer improved energy density but demand enhanced thermal management. Routine maintenance is straightforward—just perform regular connector inspections.

I follow technological advancements to see the future of pure electric vehicle batteries. Mainstream lithium-ion batteries such as LFP and NMC types have matured, enabling the widespread adoption of electric vehicles, but challenges remain in charging time and safety. Current R&D focus is on solid-state batteries, which offer higher energy density, charge in just ten minutes, and are fireproof, with mass production expected by 2030. Companies like and CATL are testing this technology, which can significantly extend driving range. Meanwhile, recycling mechanisms are being optimized to repurpose old batteries for energy storage devices, making them more sustainable. Supporting the expansion of fast-charging networks allows drivers to enjoy the benefits of innovation.
