The urge to reduce the harmful effects due to environmental changes and create a sustainable future has given rise to the demand for solid-state batteries. As the technology moves to electronic vehicles, solid-state batteries are proving to be a potential game changer for EVs. A Solid-State Battery is a rechargeable battery that uses solid electrolytes replacing liquid or polymer electrolytes used in lithium-ion batteries. They can be charged faster and have high energy density compared to lithium batteries. They last longer and ensure safety from fires or other explosions. High energy density ensures more energy storage in smaller packages. Due to the increased risk of high heat generation inside lithium-ion batteries, many companies are shifting focus to manufacturing solid-state batteries for a sustainable future. We will briefly discuss the Top 10 companies involved in developing solid-state batteries.
1. QuantumScape
QuantumScape is an industry-leading company based in the US, specializing in developing solid-state batteries for EVs. In 2012, Volkswagen partnered with QuantumScape, investing considerable amount of nearly $100 million in the company. Now, the company is backed by prominent names such as Bill Gates, Continental AG, etc. Their prototype battery can charge up to 80% capacity faster than a conventional battery in 15 minutes. They also introduced solid-state separators that enable higher battery charge and prevent failure.
2. Toyota
Next on the list is Toyota, known for its innovative technology. The company has filed more than a thousand solid-state battery patents to date. Their goal is to develop batteries for hybrid vehicles along with EVs. Their batteries can run up to 700 km on a full charge. They continuously invest in research and development to make solid-state batteries. They have announced to create vehicles by 2025 powered by high-performance batteries and internal combustion engines.
3. Solid Power
Solid Power manufactures solid-state rechargeable batteries for EVs. Their batteries are 50% more dense than traditional lithium batteries. Electronic devices like portable electronics and aircraft can be charged using Solid Power batteries. They are highly flame resistant to ensure safety from fire and other dangers. They are currently engaged in the production of 20Ah multi-layer all solid-state metal batteries in Colorado. By 2026, their goal is to develop batteries for cars.
4. Panasonic
Panasonic and Toyota have together formed a joint venture named Prime Planet Energy & Solutions, Inc. to develop cost-efficient and high-capacity solid-state batteries. Panasonic has filed for over 445 battery patents. Panasonic is a leader in developing durable batteries to eliminate the risk of leaks and fire explosions otherwise caused by liquid electrolytes. They are planning to invest in R&D to revolutionize the industry.
5. Ampcera
Established in 2017, Ampcera has over 100 industry customers and R&D partners. Ampcera is a solid-state battery manufacturing company specializing in developing high-performing solid electrolytes for use in EVs. They have patented their technology. Its electrolyte membrane provides high conductivity, critical current density, and a controllable thickness of 20 to 75 microns. Their electrolytes are relatively cheaper and takes less time to charge.
6. BrightVolt
BrightVolt manufactures solid-state lithium-polymer batteries for IoT devices. By using a proprietary polymer matrix electrolyte, they supply batteries that are more reliable and stable than conventional lithium-ion batteries. Polymers act as electrolytes that tend to have high energy density. These electrolytes are created in a way to overcome the shortcomings of liquid electrolytes. BrightVolt solid-state batteries are created using polymeric solid ion-conducting elements that are non-volatile, ensuring superior safety and efficiency.
7. Honda
Honda is engaged in the development of high-quality solid-state batteries in partnership with General Motors and Sony to achieve carbon neutrality. They have invested around 43 billion Yen (approximately $295 million) in building a production plant in Japan to create solid-state batteries for EVs by 2028. Honda is continuously involved in researching new technologies that eliminate the problem of dendrites.
8. SolidEnergy Systems
Founded by Dr. Qichao Hu in 2012 in Woburn, Massachusetts, SolidEnergy Systems uses lithium metal technology to produce solid-state batteries. Their lithium metal battery cells have an energy density of 400Wh/kg. Companies like General Motors, Honda, and Hyundai have brought their stake in the company. They have used AI algorithms to solve security problems. General Motors invested $139 million in SES to develop lithium metal battery cells for cars by 2025.
9. ProLogium Technology
ProLogium is a Taiwan-based company involved in the mass production of solid-state lithium ceramic batteries. Its factory unit has a production capacity of 40 MWh. They produce batteries that are used in consumer and wearable electronic products. They are also expecting to launch solid-state batteries for the EV market. Industry stalwarts like FAW Group, Bank of Group Investment, and dGav Capital have invested $100 million in developing solid-state lithium batteries for EVs. Their batteries offer up to 56 % higher density than conventional lithium-ion batteries.
10. Ilika Plc.
Ilika Plc is known for developing solid-state batteries for various applications such as MedTech, Industrial IoT, EVs, and Consumer Electronics. It has partnered with major companies like Shell, Toyota, Murata, and other leading brands to manufacture customized batteries.
