What specific problem are you solving?
One of the key issues in sustainable energy is that while the world rapidly shifts to greener sources, it remains ironically reliant on non-green battery technologies. Conventional batteries rely on toxic metals like lithium, nickel, lead, and cobalt, which come with environmental and human health risks from hazardous mining and toxic waste. Safety hazards are also prevalent, as these materials can overheat or combust under certain conditions. Additionally, recycling processes are energy-intensive and inefficient, leading to further pollution and resource depletion. As global demand for cleaner power grows, relying on finite metals places a strain on supply chains, drives up costs, and increases geopolitical tensions. The overarching challenge is to develop an eco-friendly, safe, and reliable energy storage solution that minimizes environmental impact, reduces safety concerns, and ensures long-term sustainability.
What is your solution?
Our proposed solution is a next-generation, paper-based battery chemistry that eliminates the need for harmful metals like lithium, nickel, or cobalt. Engineered with renewable, non-toxic materials, it offers superior safety: the cells are leak-proof, fire-resistant, and explosion-proof, addressing critical hazards in conventional batteries. From a cost perspective, our input materials are up to ten times cheaper than lithium chemistries, enabling a potential price point of just $50 per kWh at scale, significantly lower than the $100–$130 range typical for lithium-based solutions. This affordability extends across manufacturing, distribution, and integration in applications spanning from IoT devices to building-scale energy storage. Beyond cost and safety, sustainability is at the forefront of our design. Thanks to responsibly sourced materials and a compostable end-of-life pathway, our product can achieve up to a 95% reduction in its carbon footprint. By combining safety, cost-effectiveness, and environmental stewardship, we aim to deliver a breakthrough energy storage system that truly aligns with global commitments to cleaner, greener power.
Who does your solution serve, and in what ways will the solution impact their lives?
Our paper battery solution offers transformative impacts on environmental, economic, and societal levels. By leveraging our proprietary hydrogel-reinforced cellulose paper (HRCP) as both the electrolyte and separator, we eliminate hazardous chemicals and ensure safer manufacturing, usage, and disposal. Unlike conventional batteries that often contribute to e-waste, our quasi-solid-state design enables easier recycling and degradation, reducing strain on waste management systems. Furthermore, the use of abundant materials and a simplified production process keeps costs low—potentially $50 per kWh at scale, compared to $100–$130 for lithium-based options.
This technology also cuts the carbon footprint by up to 95% through responsible sourcing and a compostable end-of-life pathway. Since the manufacturing process closely mirrors that of lithium-ion batteries, commercialization can proceed faster, at a lower cost, and without relying on the supply chains largely controlled by China and the United States. By producing these batteries locally in Singapore, we bolster energy security, create jobs, and foster regional autonomy in clean energy development. Overall, safer handling, reduced environmental impact, and affordability position our paper battery innovation as a critical driver for accelerating the global transition toward truly green and resilient energy storage.
