Technology & Quality / Semi-solid Battery Technology_Zishine Power Bank, Earbuds & Rechargeable Batteries

Company Technology Overview

Zishine Energy (Shenzhen) Co., Ltd. pioneers advanced semi-solid-state battery technology, balancing ultra-high safety, elevated energy density and scalable mass production. We deliver reliable, high-performance cell solutions for new energy vehicles, energy storage and special power supply scenarios, redefining the benchmark of lithium battery safety & cycle quality.

As a professional new energy enterprise rooted in Shenzhen, Zishine Energy has independently developed proprietary semi-solid-state battery core materials, composite gel electrolyte and integrated cell forming processes. Our semi-solid system drastically cuts flammable liquid electrolyte content while retaining high ionic conductivity, solving the safety bottleneck of conventional liquid lithium batteries and the high-impedance mass-production pain point of all-solid-state batteries. Supported by closed-loop R&D, intelligent manufacturing and full-link quality testing systems, our semi-solid batteries achieve stable batch consistency, outstanding cycle durability and extreme environmental adaptability, providing industrial-grade high-quality power storage solutions for global clients.

Core Technical Breakthroughs & Unique Barriers

Proprietary Composite Semi-Solid Electrolyte

We developed self-formulated gel polymer solid-liquid hybrid electrolyte, limiting free liquid electrolyte content to 5%-10% inside cells. Solid matrix encapsulates liquid components to suppress electrolyte leakage and liquid flow inside cells; Unique inorganic solid filler modification inhibits lithium dendrite growth during long-cycle charging, eliminating hidden short-circuit hazards; Maintains ionic conductivity comparable to liquid electrolyte, avoiding the high interface impedance defect of pure all-solid cells. Unlike generic semi-solid solutions in the market, our electrolyte formula passes 1000+ thermal abuse lab verifications, fundamentally slowing thermal runaway propagation speed.

Optimized Cell Internal Architecture & Electrode Matching

Adopt high-loading positive electrode + silicon-carbon composite anode matched with semi-solid electrolyte, lifting single-cell energy density to 320–360 Wh/kg, far exceeding 200–260 Wh/kg of traditional liquid lithium cells; In-situ solidification forming process: electrolyte uniformly cured inside electrodes during production, improving internal structural stability and reducing cell swelling rate under long cycles; Compatible with mainstream large cylindrical & prismatic cell specifications, supporting customized cell design for vehicle and energy storage packs.

Mass Production Compatibility & Industrialization Edge

Our semi-solid production process shares over 80% equipment compatibility with existing liquid lithium production lines, requiring only targeted upgrades of mixing, coating and solidification stations. We avoid the ultra-high investment threshold of all-solid-state pilot lines, enabling stable mass production at controllable cost while retaining consistent batch quality. Our Shenzhen production base runs GWh-level semi-solid cell production lines with full automatic closed workshops.

Five Core Performance & Quality Advantages

Intrinsic Ultra-High Safety

Low flammable liquid content drastically reduces fire/explosion risks. Cells pass full abuse tests: acupuncture, 150°C high-temperature baking, 10-ton extrusion, overcharge & short-circuit triggering no violent combustion. Multi-layer thermal barrier structure cuts heat transfer between adjacent cells for pack-level safety.

Superior Energy Density & Longer Endurance

Single cell energy density 320–360 Wh/kg; for EV power packs, same weight battery delivers 30% longer driving range than traditional liquid lithium systems, effectively resolving range anxiety.

Extended Cycle Life & Stable Long-Term Quality

Under standard charge-discharge conditions, cells sustain ≥3,000 full charge-discharge cycles with capacity retention above 80%. The solid electrolyte matrix restrains electrode material pulverization, ensuring consistent performance after years of real-world operation.

Wide-Temperature Environmental Adaptability

Stable discharge performance maintained within -30°C ~ 65°C temperature range. No sharp capacity attenuation in cold northern regions or high-temperature tropical environments, suitable for outdoor energy storage and off-road vehicles.

4C Fast Charging Without Shortening Service Life

Support 4C fast charging, reaching 10%–80% SOC within 15 minutes. Our electrolyte structure avoids rapid aging under high-rate charging, balancing charging efficiency and long-term battery quality.

Full-Link Strict Quality Control System

To translate lab technical advantages into consistent industrial product quality, Zishine Energy builds a full-process quality management system covering R&D raw material incoming inspection → production online monitoring → finished cell reliability testing → post-delivery tracking.

1

Raw Material Incoming Full Inspection

Every batch of solid electrolyte matrix, electrode active material, conductive agent and separator undergoes component purity, stability and compatibility testing; unqualified materials are fully rejected to eliminate upstream quality risks.

2

Intelligent Closed Production Online Monitoring

Automatic optical inspection, thickness monitoring and electrolyte solidification uniformity detection installed at each production station. Real-time data recording for every single cell, automatic sorting of defective products to guarantee batch consistency rate ≥99.2%.

3

Multi-Dimensional Finished Cell Reliability Laboratory

Independent third-party standard testing lab equipped with thermal abuse, cycle aging, vibration, extrusion, low/high temperature test benches. Each cell model completes 6-month accelerated aging verification before formal mass launch; all products comply with GB, IEC, UL safety certification standards.

4

Whole Lifecycle Quality Traceability Mechanism

Unique QR code trace label attached to each cell, recording raw material batch, production time, test data and shipment information. Real-time quality feedback system supports rapid positioning of abnormal products for continuous process optimization.

Industrial Application Scenarios

New Energy Vehicles

High energy density + high safety pack solutions for pure electric passenger cars, light commercial vehicles and logistics vehicles; lower pack weight, longer mileage and better collision safety performance.

Stationary Energy Storage

Grid-side energy storage, household distributed storage and industrial backup power; long cycle life and wide-temperature performance reduce post-operation replacement cost for energy storage stations.
