Tianjin Battery Tech Firm Eyes ASSBs by ’26

In recent years, the demand for advanced battery technologies has surged, particularly in the electric vehicle (EV) sector. One notable player in this field is Doctors (Tianjin) Energy Technology Inc., a Chinese solid-state battery technology company. The firm is set to revolutionize the battery landscape by mass-producing quasi-solid-state batteries starting in October 2024, with plans to transition to all-solid-state batteries (ASSBs) by 2026. This article delves into the technical features, types of batteries, and the implications of this technology for the future.

Technical Features of ASSBs

All-solid-state batteries (ASSBs) are considered the next generation of battery technology due to their enhanced safety, energy density, and cost-effectiveness compared to traditional lithium-ion batteries. Below is a comparison table highlighting the key technical features of ASSBs versus conventional lithium-ion batteries.

Feature	ASSBs	Lithium-Ion Batteries
Electrolyte Type	Solid electrolyte	Liquid electrolyte
Energy Density	Higher (up to 500 Wh/kg)	Lower (up to 250 Wh/kg)
Safety	More stable, less risk of fire	Prone to thermal runaway
Temperature Range	Operates effectively in extreme conditions	Limited performance in extreme conditions
Cycle Life	Longer (up to 3000 cycles)	Shorter (up to 1000 cycles)
Manufacturing Cost	Higher initial cost	Lower initial cost
Environmental Impact	Less toxic materials	Contains toxic materials

Types of Batteries

The battery industry categorizes batteries based on the proportion of liquid electrolytes they contain. Understanding these types is crucial for selecting the right battery technology for specific applications. Below is a comparison table of different types of batteries.

Battery Type	Liquid Electrolyte Proportion	Characteristics
Liquid	25%	High energy density, but less safe
Semi-Solid	5-10%	Balances safety and energy density
Quasi-Solid	0-5%	Improved safety and energy density
All-Solid	0%	Highest safety and energy density, ideal for EVs

The Future of Battery Technology

Doctors Energy is at the forefront of this technological shift. The company is constructing a new 10 GWh solid-state lithium-ion battery facility in Baodi, Tianjin, with an investment of 5 billion yuan (approximately $700 million). This facility is expected to begin mass production in late 2025, with full production of ASSBs by 2027.

The advancements in solid-state battery technology are not just limited to energy density and safety. They also promise lower costs in the long run, making them a viable alternative to lithium-ion batteries, which currently dominate the electric vehicle market. As countries worldwide, including China, ramp up their efforts to develop solid-state batteries, the competition is intensifying.

The Role of Local Support

The local economic development zone in Baodi is playing a crucial role in supporting Doctors Energy’s initiatives. The district is rapidly positioning itself as a hub for battery innovation, integrating into the regional battery supply chain. This support is vital for the company’s growth and the overall competitiveness of the energy sector in Baodi.

Furthermore, financing from Tianjin SME Credit Financing Guarantee Co Ltd, the largest state-owned credit financing guarantee company in Tianjin, is bolstering Doctors Energy’s projects. This financial backing aligns with national strategies and industrial policies, ensuring that the company can secure both equity and debt financing.

Conclusion

The advancements in solid-state battery technology, particularly by companies like Doctors Energy, are set to transform the energy landscape. With plans to mass-produce quasi-solid-state batteries and transition to all-solid-state batteries by 2026, the future looks promising. As the industry evolves, the focus on safety, energy density, and cost-effectiveness will drive innovation and adoption in various sectors, especially in electric vehicles.
