British scientists have developed prototypes of all-solid-state thin-film batteries. At present, British scientists have successfully constructed prototypes of all-solid-state thin-film batteries, and achieved the expected results. The technology was jointly developed by Ilika and Toyota. Ilika is a British basic materials research and development company that is assisting Toyota in developing multiple technologies, including the development of solid electrolytes. The joint project development has created a new thin-film battery production technology that is suitable for large-scale production. Ilika's all-solid-state thin-film battery has a full range of performance improvements compared to traditional batteries and can meet the needs of important market segments: the thickness and weight of the battery are reduced by 30%; the range of electric vehicles is greatly increased, and only a few Charging in minutes; the grid can equip renewable energy projects with energy storage systems that can last for decades. More importantly, with the expansion of production scale, because the thin-film production technology and the photovoltaic and semiconductor industries have many common points, the production cost of all-solid-state thin-film batteries will also drop rapidly at the same rate. The battery has been developed for 150 years, but the structure of the battery has not changed significantly. No matter which electrochemical system is used (such as a lead-acid battery, a nickel-metal hydride battery, or a lithium-ion battery), the electrode needs to be wetted by the liquid electrolyte and react with it to generate current. This coexistence of solid state and liquid state inevitably leads to a larger battery and the risk of liquid leakage. Therefore, the all-solid battery structure is widely regarded as a more attractive solution.
