Semi-Solid State Power Batteries
Introduction to Semi-Solid State Technology
AIMRSE's semi-solid state batteries replace most liquid electrolyte with a polymer/ceramic hybrid gel, dramatically enhancing safety by preventing leakage, thermal runaway and dendrite penetration. This innovative architecture delivers energy densities up to 350 Wh/kg with exceptional coulombic efficiency. Our proprietary electrode-electrolyte interface optimization, combined with high-nickel NMC cathodes and silicon‑graphite anodes, enables a wide electrochemical window (up to 4.4V) and reliable operation from -40°C to 65°C. Unlike pure solid-state designs, our cells leverage conventional manufacturing lines for cost-effective scalability. They pass all UN38.3, UL 2580 abuse tests (nail penetration, overcharge) with substantial margins, making them the preferred choice for automotive OEMs, aerospace and high-end industrial applications demanding maximum safety and energy density. Coupled with long cycle life (>3000 cycles) and 4C fast charging capability, AIMRSE semi-solid cells redefine performance standards.
Strategic Application Fields
The unique properties of AIMRSE semi-solid state power batteries open new possibilities across industries that demand uncompromised energy, power, and safety. Their ability to deliver high sustained discharge rates without thermal accumulation makes them particularly suited for the following domains:
High-Performance Electric Vehicles (EVs)
Automakers seeking extended range and rapid charging turn to AIMRSE semi-solid cells. With energy density exceeding 320 Wh/kg at the cell level, our batteries enable EV ranges beyond 800 km on a single charge. The low internal impedance and optimized electrode architecture support 4C fast charging, adding 300 km of range in under 10 minutes. Furthermore, the inherent thermal stability reduces cooling system complexity, contributing to overall vehicle lightweighting.
Aerospace & Unmanned Aerial Systems (UAS)
In the aerospace sector, mass and reliability are non-negotiable. AIMRSE offers customized semi-solid cells with energy densities up to 350 Wh/kg and the ability to operate in extreme temperature gradients. Whether for high-altitude pseudo-satellites (HAPS), electric vertical takeoff and landing (eVTOL) aircraft, or tactical UAVs, our cells provide the gravimetric efficiency and safety margins required for flight-critical applications. The low vapour pressure of the semi-solid electrolyte also ensures stable performance in reduced-pressure environments.
Defense & Tactical Equipment
Military operations demand power sources that are rugged, non-volatile, and capable of silent watch. AIMRSE semi-solid cells meet MIL‑STD‑810 standards for shock, vibration, and humidity. Their non-flammable nature and ability to withstand ballistic impact without thermal runaway provide a decisive safety advantage for soldier-worn electronics, unmanned ground vehicles, and naval systems. Enhanced pulse power capabilities support radar and communication suites in the most demanding theaters.
Industrial Robotics & Heavy-Duty Automation
For automated guided vehicles (AGVs), mobile manipulators, and port automation equipment, AIMRSE semi-solid cells deliver high cycle life ( >3000 cycles at 80% DOD) and the ability to sustain high C-rates without accelerated aging. The robust mechanical design and wide operating temperature range (-30°C to 65°C) ensure uninterrupted operation in warehouses, foundries, and outdoor logistic hubs. Customized prismatic formats simplify integration into existing battery compartments.
Tailored Cell & System Customization
AIMRSE recognizes that each mission profile or vehicle platform has unique power and packaging requirements. Our semi-solid state platform is highly adaptable, allowing us to co-engineer solutions that integrate seamlessly with your system architecture.
Performance Parameter Engineering
We fine-tune electrode loadings, electrolyte composition, and separator thickness to optimize for either maximum energy density, peak power output, or ultra-long cycle life. Whether you need a cell optimized for 5C continuous discharge or one that delivers 4000 deep cycles, our team can tailor the electrochemical design to meet your targets.
Mechanical Form Factor & Integration
Beyond standard pouch and prismatic formats, AIMRSE offers custom dimensions, tab locations, and compression-tolerant designs for battery pack integration. Our engineers work with your mechanical team to ensure drop‑in compatibility, simplifying thermal management and busbar connections. For high-volume programs, we can develop application-specific cell cans and venting mechanisms.
Advanced BMS & Safety Algorithms
To fully leverage the capabilities of semi-solid chemistry, we co-develop battery management system (BMS) firmware with state-of-charge (SOC) and state-of-health (SOH) models calibrated specifically for our cells. This includes adaptive algorithms for fast charging, cell balancing, and early detection of internal anomalies, ensuring maximum safe utilization of the available energy.
Joint Development & Technology Roadmapping
For strategic partners, AIMRSE offers collaborative programs to explore next-generation materials, such as lithium metal anodes or high-voltage cathodes integrated with our semi-solid matrix. Together, we can co-develop cells that push beyond 400 Wh/kg while maintaining the safety profile that defines our technology.
