Unlike conventional lithium-ion cells that rely on flammable liquid electrolytes, solid-state batteries use solid materials to transport ions between electrodes. This fundamental shift enables higher energy density, improved thermal stability, and a much wider operating window. These characteristics are especially valuable for electric vehicles, aerospace platforms, and stationary storage systems where safety and reliability are critical.

TOBGROUP works with sulfide, oxide, and polymer-based solid electrolytes, each offering different advantages in conductivity, mechanical behavior, and chemical compatibility. Through controlled powder processing, layer deposition, and densification techniques, we optimize ion transport while maintaining the structural integrity required for long-term cycling.

The interfaces between solid electrolytes and electrodes often determine whether a solid-state cell succeeds or fails. Our coating, lamination, and pressure-controlled assembly processes are designed to reduce contact resistance, limit unwanted side reactions, and suppress lithium dendrite growth, helping to maintain stable performance over extended use.

Moving from laboratory cells to industrial production requires more than materials breakthroughs. TOBGROUP operates pilot lines that integrate dry and semi-dry electrode fabrication, solid electrolyte layer formation, multilayer stacking, and high-pressure cell assembly. These platforms allow customers to validate processes before committing to full-scale factories.

Solid-state cells are evaluated across energy density, cycle life, thermal behavior, and mechanical durability. This testing framework ensures that performance gains do not come at the expense of safety or reliability when cells are used in real applications.

By combining equipment, process know-how, and validation infrastructure, TOBGROUP supports the industrialization of solid-state batteries, helping partners bridge the gap between research prototypes and mass-produced energy systems.

By reducing dependence on lithium and cobalt, sodium-ion technology improves supply security and lowers material costs. This also supports more sustainable battery production, particularly for large-scale energy storage.

Our work covers Prussian blue analogues, layered oxides, and polyanionic cathode materials. Processing and surface-control techniques are used to improve crystal stability, moisture tolerance, and electronic conductivity.

Hard-carbon anodes are tailored for sodium storage through careful control of pore structure, surface chemistry, and particle morphology, balancing capacity, efficiency, and long-term stability.

Electrolyte formulations and formation protocols are optimized to stabilize the solid electrolyte interphase (SEI), reduce irreversible capacity loss, and extend cycle life.

Sodium-ion cells are validated in cylindrical, prismatic, and pouch formats, allowing consistent performance and cost evaluation across different application needs.

TOBGROUP supports the transition of sodium-ion batteries from pilot production to large-scale deployment in energy storage and electric mobility markets.

The lithium-sulfur reaction provides a much higher specific energy than traditional intercalation-based batteries, making it attractive for long-range and weight-sensitive applications.

Porous carbon matrices and conductive frameworks are engineered to confine sulfur and its reaction products, maintaining electrical connectivity and high material utilization.

Separator coatings, functional interlayers, and electrolyte control are used to limit polysulfide migration, reducing capacity loss during cycling.

Surface treatments and electrolyte formulations help suppress dendrite growth and stabilize the lithium anode, improving both safety and lifespan.

TOBGROUP supports the production of thick, high-sulfur-loading electrodes through precision coating, drying, and calendaring platforms.

Pilot-line manufacturing and testing systems allow laboratory lithium-sulfur cells to be evaluated and prepared for practical deployment.
