The Most Important Battery-Tech IPO since Tesla
Updated: Dec 20, 2020
For many years, EVs (Electric Vehicles) relied on Nickel-Metal Hydride (NiMH) cells and lead-acid cells for their batteries (and some still do). But then Tesla came along and made the case for EVs to use Li-ion (lithium-ion) batteries. Li-ion batteries are lighter, faster charging, more reliable, more temperature tolerant, and have longer life spans than the Nickel-Metal Hydride batteries. Tesla powered its initial roadster on 6,831 individual Li-ion cells, which was the “first highway legal serial production all-electric car to use lithium-ion battery cells” (Wikipedia). The early use of Li-ion batteries has been one of the key contributors to Tesla’s success.
Now, QuantumScape, founded in 2010, is eliminating Li-ion batteries and replacing them with next-gen solid-state lithium-metal batteries.
