New Solid State Battery Technology for Electric Vehicles

New Solid State Battery Technology

A recent study showed that batteries with a solid electrolyte can provide a more powerful battery than a Li-ion one. This technology is also safer than Li-ion batteries because it has no liquid components. In addition, this type of battery can be made of ceramics or solid polymers. The researchers say that their prototype pouch cell contains a significant amount of energy and can be 50% smaller than a conventional Li-ion battery.

A company called QuantumScape has plans to go public in September 2020. They have agreed to locate a production plant in Germany and pilot a product. In addition, Volkswagen has invested $100 million into the solid-state battery company and plans to invest up to $200 million in the technology by 2020. However, there are still a few hurdles to overcome before solid-state batteries are mass produced. A few other companies have shown interest in the technology, including Samsung, TSMC, and Tesla.

The solid-state silicon battery can overcome several limitations of conventional batteries, including safety and cost. In the past, sulfide-based solid electrolytes have been thought to be unstable, but new studies have shown that the kinetic stability of the latter is superior. In addition, it is possible to design a stable anode and cathode using the same materials. The researchers are confident that this technology will revolutionize the electric car industry.

Next-generation solid-state batteries rely on a silicon-based anode and sulfide solid electrolyte. The metallic anode requires high temperatures for charging, and this limits battery charging rates. The Silicon-Silicon alloy anode allows for faster charging at low temperatures. Ultimately, this means more energy for the driver and better vehicle performance. These breakthroughs will lead to more efficient and environmentally-friendly vehicles.

Developing a cost-effective solid-state battery is critical to achieving a sustainable EV market. However, the cost of production is currently much higher than that of lithium-ion batteries. According to BloombergNEF, it is anticipated that the cost of solid-state batteries will be about 40% of the current cost of lithium-ion batteries. The costs of developing and manufacturing them will be significantly lower than the costs of lithium-ion batteries.

The biggest problem with current lithium-ion batteries is their interfacial instability. This happens when a liquid is forced to move from one electrode to another, which is not a good idea for a battery. The anode can’t hold up for a few minutes after a full charge. A high-voltage cycle can lead to a lower-energy-density battery. This type of technology is based on lithium-ion batteries.

The advantages of solid-state batteries over lithium-ion batteries include a lower cost and higher energy density. They also can be manufactured at lower costs than their liquid-ion counterparts. While the benefits of these batteries are similar to those of lithium-ion batteries, they are not yet ready for widespread commercialization. Nevertheless, they offer a number of advantages over conventional batteries. For example, the sulfide-based cells used by Solid Power are safer than lithium-ion batteries, and they are made from a similar infrastructure.
