Lithium-ion batteries are facing scrutiny due to safety hazards, with recalls of nearly 1.9 million power banks and tens of thousands of e-bikes issued by the US Consumer Product Safety Commission in 2025. The long-awaited solution, solid-state batteries, has proven elusive, but a new type of battery called semi-solid-state has emerged. These batteries feature a gel-like electrolyte that mitigates the risks associated with traditional lithium-ion batteries, such as overheating and fire. Companies like Ride1Up and Giant are leading the way in adopting semi-solid-state technology for e-bikes, with Ride1Up announcing the Revv1 EVO, capable of enduring over 1,200 charging cycles, and Giant collaborating with T&D on several new models. This technology is also being explored for applications in drones, electric vehicles, and home power stations.
Why It Matters
The shift to semi-solid-state batteries represents a significant advancement in battery safety and efficiency. Traditional lithium-ion batteries are known for their volatility, leading to safety recalls and consumer concerns. By moving towards semi-solid-state technology, manufacturers can reduce the risk of battery failure and extend the lifespan of power storage solutions. This transition is critical as the demand for safe, reliable energy storage continues to grow across various sectors, including electric mobility and renewable energy systems. The market’s evolution towards these improved battery technologies reflects ongoing efforts to enhance safety and performance in energy storage.
