Quantumscape, an American battery technology company, is likely to be the first firm in the world to introduce solid-state batteries to the market for electric vehicles (EVs) within the next two years, as it claimed that people would be able to buy an electric car with it. will be able Batteries as early as 2024.

According to the company, a vehicle using its solid-state battery can travel more than 400 miles on a single charge before recharging in 15 minutes. Because of such specifications, solid-state EVs will have a significant edge over their rivals that rely on lithium-ion batteries, which take about two to three hours to fully charge.

Compared to Li-on options, all-solid-state batteries (ASSBs) promise longer life, faster charge times, and safer chemistry.

However, producing them on the scale needed to power millions of automobiles will not be easy. Therefore, QuantumScape and other battery-focused businesses such as Solid Power in Colorado and Prologium Technology in Taiwan, as well as major automakers such as Nissan, are vying for market share.

According to the company, ASSB’s cells have been rapidly charged 400 times in a row (from 10% to 80% in 15 minutes), and some of them have experienced nearly 1,000 total discharge and charge cycles, compared to conventional Li- Any solid-state effort on sale or to date has failed to reach that point.

ASSB promises a far higher energy density than current Li-on power packs, meaning they will produce more power relative to their size or weight.

Leading lithium-ion batteries have an average energy density of about 600 watt-hours per liter, but QuantumScape estimates their ASSB will reach 1,000 watt-hours per liter. It is believed to increase the range of a typical EV to 375-400 miles.

Since lithium ions often form dendrites at the anode of a lithium battery over the course of several charge cycles, creating highly reactive stalagtite that can result in power loss and even fire, QuantumScape has developed its own battery development process. As part of is developing its own battery with ceramic electrolyte. ,

Despite the fact that QuantumScape’s ASSB requires lithium to manufacture, the business claims that the dendrites will not be a problem.

Similarly, there will be some challenging factors regarding which battery manufacturers will have to find solutions. According to experts, the great energy density of the battery should be used safely by ASSB developers, considering the explosion cases related to Li-ion batteries.

According to studies, ASSBs are said to be safer than Li-ion batteries overall, but their designers are aware of some potential dangers. It is understood that doubling the density means that the energy will be much higher and therefore ensuring safety will be of utmost importance to the ASSB.

In this case, QuantumScape’s current anode-free design does not completely avoid this problem. But the company said it still needs testing, but expects its ASSBs to be more secure than Li-ion.

However, the US company said its initial prototype cells could be sent to Volkswagen, its biggest stakeholder, as early as this year.

It also intends to build a pre-production line by the end of 2023 and supply the ASSB to Volkswagen for inclusion in a test vehicle scheduled for 2024 or 2025. Until then, QuantumScape hopes to have its first solid-state battery to leave the Gigafactory.

The revolutionary promise of EVs powered by solid-state batteries has prompted auto makers to join the fight with businesses like QuantumScape.

For example, last year, Toyota announced a $13.6 billion investment in a program for in-house battery development and manufacturing that would also include solid-state batteries. He predicted this year that his first solid-state battery electric vehicle (SSBEV) would hit the roads in 2025.

Meanwhile, according to reports, other companies like Nissan have a more broad, but lofty goal of offering solid-state batteries. It has been researching and developing solid-state technology for the past 10 years, and the company now claims that it plans to start mass production batteries by 2028.
