Project introduction:

Lithium slurry battery is a new type battery technology for energy storage with independent intellectual property rights. It is suitable for capacity-type energy storage applications with discharge duration of more than 4 hours, including photovoltaic + energy storage, wind power + energy storage and peak load shifting.All or part of the electrodes of the lithium slurry battery are composed of slurry-state lithium storage active material,  conductive agent and electrolyte. It has two significant technical characteristics which are ultra-thick slurry electrode and maintainable regeneration.The intrinsic safety of the battery is realized through the semi-open architecture and the safety agent injection technology, where the electrochemical energy storage safety accident is eliminated; The energy consumption cost of the full life cycle is reduced (50% lower than the existing lithium iron phosphate battery) through the short-range preparation technology of ultra-thick slurry electrode and on-line maintenance and regeneration technology;The residual value of battery recovery can be greatly improved while reducing the environmental load  through the development of the material system free of impurity element pollution in the life cycle and the repair and regeneration technology of key materials.Therefore, the lithium slurry battery has solved the three major pain points (cost, safety and recovery) faced by the application of electric energy storage battery at present, thus the application prospect of energy storage is broad.At the early stage of technology research and development, the project team insisted on taking market application as the guide, and planned the market application of lithium slurry battery technology according to the market demand of capacity type long-term energy storage, laying a good foundation for future market promotion.In addition, some downstream products of lithium slurry energy storage battery have also been tested by the third party and used by customers, with good results.
