In the solid-state battery track, TAICO, as a representative of China’s second echelon, differentiates itself from the sulfide routes of CATL and BYD by manufacturing solid-state batteries through oxide-polymer composite electrolyte technology.

It uses oxide-polymer solid-state batteries to enter high value-added scenarios, and simultaneously reserves sulfide electrolyte technology to achieve a leap from “material innovation” to “ecological integration”.

Relying on technology iteration and industrial chain collaboration, TAICO has achieved the transformation from a pioneer to a leader in global solid-state battery energy storage products.

After the GWh-level production line is put into operation in 2025, our solid-state batteries will accelerate the penetration of household energy storage, industrial and commercial energy storage, and grid frequency modulation.

Technical advantages of solid-state batteries

1. Safety – zero fire, no explosion

Solid-state batteries use non-flammable solid electrolytes to replace traditional liquid electrolytes, completely eliminating the risks of electrolyte leakage, volatilization and combustion. Taking TAICO’s solid-state battery puncture test as an example, the solid-state battery achieved “zero fire” and “no explosion” in its needle puncture test, becoming the key technology for the current safety upgrade of TAICO’s energy storage system.

2. Energy Density Leap – breaking the limit of 500Wh/kg

The energy density of solid-state batteries can reach 400-500Wh/kg, which is more than 50% higher than that of liquid lithium batteries. In the industry, TAICO is the first to purchase solid-state batteries with oxide-polymer composite electrolyte technology. This technology successfully solves the interface impedance problem of solid-state batteries (interface impedance is reduced to 5Ω·cm²), and the ion conductivity is increased to 10⁻² S/cm, close to the level of liquid electrolytes. Through the verification of the lithium-sulfur solid-state battery system by the TAICO team, the capacity retention rate of 25,000 cycles is >80%, and the fast charging speed reaches 20C (charging to 80% in 10 minutes)

3. Ultra-long Cycle Life – 10,000 cycles of capacity retention rate > 80%

The solid-solid interface stability of solid-state batteries significantly extends the cycle life. Taking TAICO’s solid-state battery product T-ONE S as an example, its innovative oxide-polymer composite electrolyte system can ensure that the capacity decay of the battery after 10,000 cycles is less than 20%, which is suitable for grid-side frequency modulation energy storage systems. Compared with ordinary lithium iron phosphate batteries (decay to 80% after 5,000 cycles), solid-state batteries can reduce the life cycle cost of energy storage systems by 40%. This is highly favored by customers in Europe and the United States.

T-ONE S, the flagship solid-state product of solid-state batteries

The T-ONE S series is the flagship product of the TAICO solid-state battery series and is a wall-mounted home energy storage system product. The power is 2.5kwh-30kwh, using solid-state batteries and high-quality BMS. With automated production lines and industry-leading process design capabilities, it has excellent performance, safety and reliability. The battery cycle life is up to 10,000+, which is perfectly suitable for long-term stable operation of off-grid systems;
