Where Innovation
Meets Reliability.
Our R&D team is focused on developing customised lithium-ion battery pack solutions designed around the specific requirements of each application. We work across the complete battery development cycle, starting with understanding the application, operating conditions, power and energy requirements, space constraints, and customer-specific performance targets. Our expertise covers cell and application engineering, smart BMS development, thermal and safety design, electrical and mechanical integration, and custom pack engineering. We evaluate and select suitable cell chemistries, capacities, configurations, and electrical architectures to achieve the required voltage, energy, power, cycle life, weight, and form factor. Our team also develops and integrates intelligent BMS solutions for cell monitoring, balancing, protection, communication, and battery performance management. Thermal and safety considerations are incorporated into the design to ensure reliable operation under varying load and environmental conditions. Through prototyping, testing, validation, and design optimisation, we continuously improve battery performance, reliability, safety, and manufacturability. This application-driven R&D approach enables us to transform customer requirements into high-performance, reliable, and production-ready customised battery packs for applications including electric mobility, drones, energy storage, industrial systems, and other specialised power solutions.

We build batteries that heal the planet
Every Voltherm product is designed with circular economy principles from day one. Our manufacturing facilities utilize highly optimized resource cycles to significantly reduce net manufacturing waste while maintaining carbon neutrality targets. We don’t just minimize harm — we actively design for regeneration at every stage of the battery lifecycle.
100% Renewable Operations
Our facilities operate on dedicated solar and wind captive power, eliminating Scope 2 emissions. Excess clean energy is fed back into the local grid, turning our plants into net-positive contributors rather than consumers.
Closed-Loop Cell Recovery
Proprietary hydrometallurgical processing recovers up to 96% of active lithium and nickel from end-of-life packs. Recovered materials re-enter our production lines within weeks, closing the loop and dramatically reducing the need for virgin mining.
Ethical Mineral Sourcing
Strict blockchain-backed traceability ensures zero conflict minerals enter our supply chain. Every kilogram of cobalt, lithium, and nickel is audited from mine to cell, with full public visibility available through our supplier portal.
Design for Disassembly
Voltherm cells and packs are engineered with modular, tool-free separation of components. This approach cuts recycling energy demand by more than 40% compared to conventional battery architectures and enables rapid second-life deployment.
Water Stewardship
Our closed-loop water systems recycle over 92% of process water. Advanced filtration and zero-liquid-discharge technology ensure that not a single drop of contaminated water leaves our facilities.
