UltraXel Battery Core Technologies

UltraXel focuses on the development of wide-temperature lithium battery technologies, aiming to deliver stable and reliable power solutions for extreme conditions such as high heat, freezing temperatures, high power demands, and stringent safety requirements. By optimizing electrode materials, upgrading electrolyte formulations, applying ceramic separator technology, and enhancing conductive additives, we have significantly improved the batteries’ temperature adaptability, cycle life, and output performance. Below are our solutions across four key technical areas.
Stable operation under high-temperature conditions requires enhanced thermal and chemical integrity. UltraXel improves high-temperature performance through advanced material optimization and electrolyte design.

Cathode Material Optimization

• Nanomaterial treatments and composites with other materials improve low-temperature performance.

Anode Material Modification

• Special surface-treated graphite enhances the stability of the anode reaction at high temperatures.

• Nanomaterial treatment of silicon-based anodes, in combination with graphite, prevents expansion and gas generation under high temperatures.

High-Temperature Electrolyte Formula

• High-boiling point solvents and stable lithium salts reduce electrolyte vaporization and decomposition at high temperatures.

• High-temperature film-forming additives create an SEI layer that remains stable under elevated temperatures.

Membrane Coating Technology

Ceramic coatings (such as alumina or zirconia) on the separator improve its heat resistance and mechanical strength.

Binder Technology

Using aging-resistant binders instead of conventional SBR to extend battery life under high-temperature conditions.
Low temperatures can cause sluggish ion kinetics and high internal resistance. UltraXel addresses these challenges through electrolyte innovations, conductive additives, and electrode engineering.

Cathode Material Optimization

• Surface coating and doping modifications improve the thermal stability of the material.

Anode Surface Structure Optimization

• Artificial or natural graphite, treated with surface modification and nanomaterial techniques, enhances lithium-ion insertion and extraction performance at low temperatures.

Electrolyte

• Using low-viscosity solvents and high-conductivity lithium salts reduces impedance at low temperatures. Low-temperature film-forming additives reduce SEI layer impedance on the electrode surface, improving performance in low-temperature charging and discharging.

Conductive Additive Upgrade

• Carbon nanotubes and graphene are used as conductive agents to reduce internal resistance and improve conductivity at low temperatures.

Separator Materials

• High-porosity separators enhance electrolyte permeability, aiding ion transport in low temperatures.

Battery longevity is crucial for reducing system maintenance and improving overall reliability. UltraXel employs thermal-protective materials and intelligent safety designs to maximize service life.

Ceramic-Coated Separator

• Ceramic coatings prevent separator shrinkage at high temperatures, avoiding short circuits.

Explosion-Proof Valve Design

• CID (Current Interrupt Device) quickly disconnects overload currents.

Membrane Micropore Control

• High-precision microporous separators close the pores to cut off ion channels when the temperature rises.

Flame Retardant Electrolyte

• Incorporating flame retardants reduces the risk of combustion during thermal runaway.

For applications requiring rapid discharge and high currents, UltraXel integrates multiple structural innovations to deliver consistent high-power performance.

Multi-Tab Design

• Using multiple or full tabs for uniform current distribution, reducing internal resistance.

Electrode Plate Design Optimization

• Optimizing electrode plate area density and compaction density to lower internal resistance.

Conductive Additive Enhancement

• Using high-conductivity carbon nanotube and graphene composite additives to improve high-rate performance.

Current Collector Pre-Coating

• Pre-coating current collectors with conductive carbon to reduce internal resistance.
