Progress in Battery Technology Ensures Increased Dependability of Electric Vehicles.
Renewed Push for Electric Vehicles: A Look at VinFast and the Future of Battery Technology
Electric vehicles (EVs) are taking the world by storm, thanks to advancements in battery technology. One company leading the charge is VinFast, a subsidiary of Vingroup JSC, that's making EVs accessible to all.
A Brief History of Electric Vehicles
The tale of EVs dates back more than a century. In the early 1900s, lead-acid batteries allowed EVs to traverse up to 100 miles—a significant feat at the time. However, as roads improved and vehicles sped up, these heavy, low-energy-density batteries struggled to keep up, paving the way for internal combustion engines.
Flash forward to 1996, when an American manufacturer introduced an all-electric car fitted with antiquated lead-acid technology. The second generation, powered by nickel-metal hydride batteries, was equally uninspiring. The bottleneck? Energy density. These batteries simply couldn't store enough power to make EVs practical for daily commuting.
It wasn't until 1998 that a Japanese manufacturer introduced an EV with a lithium-ion battery, a game-changer. Lithium-ion technology could store three times more energy than lead-acid equivalents and about twice as much as nickel-metal hydride. It was the catalyst the industry needed.
The Evolution of Lithium-Ion Batteries
"Lithium-ion" isn't a single technology; it's an umbrella term for various chemistries. Most rely on a graphite anode, but the real improvements come from the cathode.
Early lithium-ion batteries combined lithium with nickel, cobalt, or manganese. Over time, manufacturers refined these blends to balance energy density, safety, and cost. The trend has been to decrease cobalt content, a precious but ethically questionable material. Today, high-nickel formulations rule the roost.
Another cathode chemistry, lithium iron phosphate (LFP), has gained popularity for its affordability and safety—with a compromise: slightly lower energy storage capacity. By 2024, LFP and nickel-manganese-cobalt (NMC) batteries are expected to power 94% of light electric vehicles worldwide, according to S&P Global Mobility.
The Future of EV Batteries
The future of EV batteries is looking bright, with advancements on the horizon.
Two promising technologies are solid-state batteries and sodium-ion batteries. Solid-state batteries could provide up to 50-80% higher energy storage compared to traditional lithium-ion batteries while reducing fire risk.
Sodium-ion batteries, while less flashy, could offer several advantages: increased affordability due to the abundance of sodium, and potential lower environmental impact due to simplified extraction processes. Their energy density is lower than LFP, but they excel in cold-weather performance.
Both technologies still face challenges, but progress is picking up speed as costs fall and performance improves. As they become more viable, EVs could soon eclipse gasoline-powered cars in longevity and reliability.
