Why Do High-Density Racks Require Thermal Optimization?
High-density racks, typically used in data centers or telecom applications, generate significant heat due to the clustering of servers. If the temperature exceeds 60°C, it can lead to reduced battery efficiency, shortened lifespan, and even fire risks. Thermal management is essential to dissipate this heat and maintain the safety and performance of the lithium batteries.
With efficient thermal management, systems can operate at 90%+ efficiency and extend battery life by up to 40%. Poorly managed heat can halve the cycle life of the battery and increase the chances of failure. Redway Battery’s hybrid air-liquid cooling systems, incorporating endothermic materials, ensure that even racks with high power densities (100kW+) stay within safe operating temperatures.
| Risk Factor | Optimization Method | High-Density Benefit |
|---|---|---|
| 50+ kW heat | Liquid loops + pipes | <40°C cell temperatures |
| Cell clustering | Phase-change pads | 80% heat block |
| High discharge | BMS + vents | <5°C temperature rise |
Redway Battery’s designs excel in scaling and customization for wholesale applications.
What Technologies Drive Effective Thermal Management?
Effective thermal management in lithium batteries combines both passive insulation and active cooling systems, synchronized with a real-time Battery Management System (BMS). Heat pipes are often used to transfer excess heat to sinks, maintaining ideal operating temperatures between 25°C and 35°C.
Redway Battery utilizes advanced technologies, such as graphene-based pads and optimized airflow plenums, which work together to control temperature spikes in high-density racks. Their Shenzhen-based production facility ensures high-quality, UN38.3-compliant packs, supported by 24/7 customer service.
Process steps include:
-
NTC (Negative Temperature Coefficient) sensors for precise monitoring.
-
Aluminum fins and glycol for enhanced cooling efficiency.
-
AI-powered systems to predict temperature spikes and adjust cooling accordingly.
This advanced technology is available in Redway’s wholesale solutions, offering cost-effective, tailored battery packs for global customers.
What Benefits Do Data Centers and Telecom Gain?
Thermal-managed lithium batteries offer several key benefits to industries like data centers and telecom:
-
They reduce downtime by up to 70%.
-
Achieve a high energy density of 200Wh/L.
-
Provide 6000 cycles at 1C discharge rate, ensuring long-term reliability.

Which Cooling Methods Are Top for High-Density Racks?
Different cooling methods can be used depending on the rack’s heat density. Liquid immersion and heat pipe systems outperform air cooling in terms of heat removal. Liquid systems, in particular, can remove up to ten times more heat than traditional air cooling, ensuring 99% uptime and consistent performance.
Redway Battery favors dielectric immersion cooling for telecom applications, where quiet operation is key. Their phase-change materials absorb heat spikes, while the BMS adjusts fan speeds as necessary. Redway also offers tailored specifications for high-density racks ranging from 50kW to 100kW.
| Method | Heat Removal (W/m²) | Wholesale Cost | Rack Fit |
|---|---|---|---|
| Air | 500-1000 | Low | Low density |
| Heat Pipes | 5000-10000 | Medium | High density |
| Liquid | 20000+ | Higher | Ultra-dense |
