Adaptive Management Of Expansion Force

Adaptive Management Of Expansion Force

Adopt flexible expansion force management technology to achieve adaptive management of battery expansion force, ensure that expansion force is always in the optimal environment, ultimately help to extend battery shelf life

Life Compensation Technology

Life Compensation Technology

Electrolyte enrichment and gas release at different stages of operation to slow down battery capacity decay, extend battery shelf life, and ultimately achieve greater value

Rapid Charge

Superconducting Electrolytes

Superconducting Electrolytes

With superconducting electrolytes technology, the transport speed of lithium ions through the liquid and interface is significantly increased, greatly improve the charge speed

Multi-stage Electrodes

Multi-stage Electrodes

Through adjusting the gradient distribution of the electrode porous structure, a high porosity structure is built in the upper layer of electrode and a dense structure is built in the lower layer, thus ensure high energy density and ultra-fast charge

Various Sides Common Graphite

Various Sides Common Graphite

Depend on adopting isotropic technology, lithium ions can be inserted into the graphite channel from any sides, thus greatly increase the charge speed

More Safety

Temperature-resistant Cathode

Temperature-resistant Cathode

High-throughput screening of the "material gene pool", lock the unique metal elements for mixing with "nickel-cobalt" and other variable-value elements to ensure energy density and increase the difficulty of oxygen release, significantly improve the thermal stability of ternary materials

Safety Coating

Safety Coating

The unique advanced Nano-coating technology forms a stable and dense solid electrolyte interface film on surface of the electrode, which greatly reduces reactivity of material and electrolyte and significantly improves  thermodynamic stability of core

Highly Safe Electrolyte

Highly Safe Electrolyte

We start to research the electrolyte which is one of the four main materials of battery, we have successfully developed a variety of functional additives to effectively reduce the reaction heat generation between solid-liquid interface by improving electrolyte genetics, which significantly improves the heat resistance temperature and the thermal safety of the battery

Self-Control Temperature

Core Self-control Temperature

Core Self-control Temperature

Self-heating technology can reach at the maximum uniform heating of core,  overcome the uniform heating of core caused by conventional heated film heating method, to preserve youth, anti-aging

Cold-resistant Cathode

Cold-resistant Cathode

The highly active cathode material makes the lithium ion fast migration and adapts to all-weather use scenarios, even when it's extremely cold

Cold-resistant Electrolyte

Cold-resistant Electrolyte

Low-viscosity electrolyte improves lithium ion conduction rate and keeps lithium ions flowing freely, especially under extreme conditions, even in ice condition, it still can enter and exit freely
