Semi-solid state battery
A new technology for the e-bike industry
Lithium-ion batteries have long been the main choice for e-bike manufacturers, but there are significant limitations with the technology. Charging times tend to be long, and production costs of high-quality items, with robust battery management systems (BMS), are high.
As a result, sub-standard products are reaching end-users through online marketplaces, leading to safety and security risks.
T&D introduces a new semi-solid state NCM lithium battery, featuring high energy density and multiple built-in security layers. Technology that's tried and tested in electric motorcycles has now been adapted to meet the e-bike sector's needs.
Sunny He, T&D founder and General Manager, said, “This battery technology represents a true game-changer for the e-bike sector. Lightweight, fast-charging and with maximized safety measures, it promises to open up new avenues of exploration, both for e-bike brands and end-users alike.”
Advantages
Light and agile, providing 830Wh at only 3.2kg.
Can be adapted to a variety of e-bike frame designs, such as integrated or tube-mounted removable, built-in downtube or seat tube, or rear rack options.
Offers a cost-effective production process, with no changes to battery production equipment required, enabling the use of mature and reliable production processes.
