The battery cell production line also integrates a quality AI large model technology, utilizing energy vibration, optical imaging, and other AI quality inspection equipment. This precisely records and inputs data into AI models for deep analysis, achieving near "zero defects" in battery cell quality, and providing solid assurance for the "military-grade" safety of the Shendun Jinbrick battery cells.

Ultra-safe, ultra-fast charging, high-rate, and ultra-durable, verified by the industry’s first “vehicle + battery pack” six serial extreme tests with power-on.

As a family known for safety, "safety" has always been Geely's top priority in car manufacturing. For the Shendun Golden Brick Battery, industry standards are merely the pass line, and achieving ultimate safety in all scenarios is the goal. Building on the battery cells' successful challenge of the 8-pin simultaneous puncture and live ammunition penetration tests, the Shendun Golden Brick Battery further aims to challenge the industry's first "whole vehicle + whole pack" six serial extreme tests while charged.

The test was conducted by the China Automotive Technology and Research Center, simultaneously evaluating the safety performance of the Lynk & Co 10 EM-P vehicle and the Shendun Gold Brick battery pack. The battery was fully charged during testing, closely simulating real user scenarios. Using the same Shendun Gold Brick battery pack, six rigorous tests were carried out consecutively: “dynamic load corrosion immersion, high-temperature charging and discharging, continuous vehicle underbody scraping, vehicle water wading with underbody scraping, vehicle bumping and water wading, and load-bearing external fire exposure.” Throughout the testing, the battery remained in a discharge state, highly simulating various extreme conditions users might encounter. Ultimately, after completing all the challenging tests, the Shendun Gold Brick battery did not catch fire or explode, the Lynk & Co 10 EM-P vehicle remained in normal condition, and all tests were successfully passed.

Behind the military-grade safety of the Shendun Gold Brick Hybrid Battery lies a series of innovative safety technologies. It adopts a self-developed multi-particle size compounding technology, unlocking the synergistic mechanism between the kinetics, high-temperature performance, and safety performance of lithium iron phosphate batteries. This achieves breakthroughs in enhancing thermal stability, alleviating volumetric expansion stress, and improving lithium-ion diffusion kinetics, thereby improving material safety and cycle life. The self-developed ultra-thin, highly heat-resistant insulating film enables the Shendun Gold Brick cell to easily withstand external mechanical damage and internal stress changes, providing the confidence for the cell to smoothly pass the 8-needle simultaneous puncture test. Geely’s independently developed “Molecular Armor” high-safety electrolyte technology ensures that the battery remains rock-solid even under extreme conditions.

Beyond "super safety," the Shendun Gold Brick hybrid battery also features ultra-fast charging, high discharge rates, and exceptional durability. Thanks to the industry-leading intelligent overclocking terminal fast charging technology, the Shendun Gold Brick hybrid battery can achieve tightly ordered lithium ions and enhance charging efficiency with the help of a special voltage harmonizer. In the SOC 80%~100% range, the Shendun Gold Brick hybrid battery can be fully charged in just 11.5 minutes. While typical batteries have a terminal charging rate of only 0.8C, the terminal charging rate of the Shendun Gold Brick hybrid battery can reach up to 1.4C, which is a 75% improvement over the industry standard.

Empowered by self-developed multi-size particle compounding technology and high-penetration electrolyte technology, the Shendun Gold Brick Hybrid Battery not only ensures the high dynamic performance required by hybrid vehicles but also features an internal resistance at a state-of-charge (SOC) far lower than that of its peers, along with the capability for high-power charge and discharge, truly achieving "low SOC as full SOC," maintaining strong performance even at low charge levels. Tests indicate that under low charge conditions below 20% SOC, the single cell can reach an acceleration power of 2100W in 5 seconds, compared to only 1700W for similar products, representing a 23.5% increase in low charge output power over competing products. Across the entire SOC range, the Shendun Gold Brick Hybrid Battery exhibits very strong performance, with a maximum discharge rate of up to 21.02C.

The traditional industry perception that "safety, performance, and longevity cannot be achieved simultaneously" has been overturned by the Shendun Golden Brick Hybrid Battery. The application of S+ technology enables the active coating of the battery's main materials, significantly reducing battery impedance while effectively preventing side reactions between the electrolyte and electrodes, ensuring the stability of the main material structure. The unique SEI film self-repair technology allows for the self-repair of cracks that appear in the SEI film during the battery's cyclic use, accelerating interface self-healing. Empowered by industry-leading technology, the Shendun Golden Brick Hybrid Battery boasts a cycle life of up to 4500 cycles, equivalent to a vehicle driving around the Earth 32 times, ensuring battery performance for a million-kilometer mileage.

With the advantages of ultra-safety, ultra-fast charging, high rate capability, and ultra-durability, the Shendun Golden Brick battery has become a new benchmark for lithium iron phosphate batteries. It is now widely used in products of brands such as Zeekr, Lynk & Co, and Geely Galaxy.
