The Singapore company introduced a new battery made from sustainable, safe materials with a production cost of only about 10% of lithium-ion batteries.
Flint, a Singaporean company specializing in developing sustainable energy solutions, is attracting attention in the field of battery technology with its advanced paper battery product. This type of battery promises to bring many impressive benefits compared to traditional energy storage solutions. Flint introduced this pioneering technology at the CES 2025 exhibition taking place in Las Vegas, USA, January 7 – 10.
Flint’s paper battery is a semi-solid battery, using a ring of hydrogel to serve as both the barrier and the electrolyte in a sheet of paper. This design is different from conventional lithium-ion batteries because it replaces toxic and geopolitically sensitive materials such as lithium, cobalt, nickel, with safe and sustainable options such as zinc and manganese.
According to company representatives, the new battery is light, flexible and adaptable in shape, which not only provides safety but also has a significantly lower cost than traditional lithium-ion batteries. The hydrogel-based design contributes to its complete decomposition within 6 weeks when buried underground, leaving no toxic waste. This makes paper batteries more sustainable than traditional batteries, which can take decades to decompose and pose major environmental risks.
Additionally, while lithium-ion batteries pose a risk of leakage, fire, and explosion, paper batteries have been rigorously tested to withstand fire, cuts, punctures, and bending. These tests confirm the safe operation of the battery.
In terms of energy efficiency, each paper battery provides a capacity of 600 mAh, enough for many consumer and industrial applications. Currently, its energy efficiency is still lower than lithium-ion batteries, but Flint is working on improvements. The company believes that paper batteries can be used in a variety of fields, from consumer electronics to industry.
The versatility of paper batteries combined with Flint’s focus on cost-effectiveness make the new batteries an attractive alternative to traditional batteries. The cost of producing paper batteries is currently equivalent to 10% of the cost of lithium-ion batteries, but the company is working to scale up production to further reduce costs and make batteries more affordable.
Flint plans to establish a pilot production facility in Singapore, and add a number of facilities in China, India, the US, and Vietnam in the future. The company aims to have the first commercial-scale paper batteries shipped by the end of the year.
