Introduction
[This article will contain a comprehensive 900+ word overview of battery technology evolution for electric vehicles, discussing their history, current state, and future developments.]
Early EVs like GM EV1 used lead-acid batteries with limited range (60-100 miles) and long charging times. Later models introduced nickel-metal hydride (NiMH) with improved energy density.
Tesla pioneered the use of thousands of small lithium-ion cells in their first production vehicle, achieving 245 miles of range and proving EVs could be high-performance vehicles.
Nissan Leaf and Chevy Volt introduced more affordable EVs using improved lithium-ion technology. Battery costs began rapid decline from $1,000/kWh toward $300/kWh.
Introduction of new cell chemistries like NMC 811 and NCA with higher energy density. Battery costs fall below $150/kWh, making EVs increasingly cost-competitive with ICE vehicles.
Lithium iron phosphate (LFP) batteries make a comeback for standard-range vehicles. Structural battery packs integrate cells into vehicle structure, reducing weight and improving efficiency.
Introduction of first-generation semi-solid electrolytes and silicon anodes commercially, offering 20-30% higher energy density and improved charging speeds.
Projected commercial introduction of true solid-state batteries with 50-100% higher energy density, faster charging, improved safety, and longer lifespans than current lithium-ion cells.
