Battery Full-dimensional Safety Protection System
Full-dimensional Safety Protection System
Intrinsic Material Safety + Structural Armor + Intelligent BMS Hierarchical Protection
Safety is the bottom-line core competitiveness of new energy batteries. Zishine Energy builds a five-level full-link safety barrier for semi-solid batteries, completely solving flammability, leakage, short circuit, thermal runaway and extreme abuse risks of traditional liquid lithium batteries.
Traditional liquid lithium batteries rely solely on BMS passive protection, which cannot fundamentally avoid hidden dangers such as electrolyte leakage, lithium dendrite piercing, thermal shrinkage of diaphragm and chain thermal runaway. Our semi-solid battery abandons the single electronic protection logic, adopting intrinsic material safety as the core, supplemented by physical structural protection, intelligent algorithm monitoring, thermal runaway isolation and full-scenario abuse verification, realizing essential safety from cell to battery pack system.
All safety indicators are based on mass production verification data. The battery achieves non-flammable, non-explosive and non-leakage performance under extreme working conditions such as acupuncture, severe extrusion, high-temperature baking, overcharge and short circuit, reaching the highest vehicle-grade safety standard in the industry.

Intrinsic Material Safety · Root-level Risk Elimination
-
Low-dose Flame-retardant Electrolyte Locking
Different from traditional batteries with 25%+ free liquid electrolyte, our semi-solid system only retains 5%-10% controllable flame-retardant electrolyte. The solid ceramic matrix completely locks free liquid, eliminating electrolyte leakage and splashing risks. No combustible liquid diffusion means no continuous combustion conditions.
-
In-situ Solid Anti-dendrite Coating
The cathode high-temperature resistant solid isolation layer and modified LLZO ceramic electrolyte jointly suppress lithium dendrite growth. It effectively prevents diaphragm piercing and internal micro-short circuit, greatly improving cell structural stability during long-term cycling and low-temperature charging.
-
Ultra-high Thermal Stability Matrix
The thermal runaway initial temperature of the cell is increased to above 280°C. The solid composite material has excellent high-temperature resistance, avoiding thermal shrinkage and structural collapse of traditional diaphragms under high heat, and greatly extending the safety buffer time from heat generation to thermal runaway.
