Development Status of Battery Energy Storage Technology

Driven by global new energy power generation, electric vehicles and emerging energy storage industries, many types of energy storage technologies have made great progress in recent years. In addition to the pumped water storage and cave-type compressed air energy storage technologies that have already been commercialized, battery energy storage technologies led by lithium-ion batteries have begun to have commercial application potential.

KIJO's lithium-ion battery energy storage technology is mainly used in data room, base station, solar power station, distributed power supply system, emergency energy storage, and microgrid energy storage.

Battery energy storage technology is expected to be dominated by lithium iron phosphate batteries, lead-carbon batteries and all-vanadium flow batteries in the short term. Lithium iron phosphate batteries are mainly used in power-side frequency modulation, grid-side energy storage, "wind power + energy storage" and other fields, and gradually expand to other application fields. With the reduction of energy storage costs and the continuous manifestation of multiple application values, lithium iron phosphate battery energy storage market space will be further expanded; lead-carbon batteries will peak cut in industrial and commercial field, and expand their applications in "photovoltaic + energy storage" and other fields, and will continue to increase service life and reduce the cost of electricity; all vanadium flow batteries energy storage demonstration project planning is intermittent. Affected by the price of raw materials, the construction of large-scale all-vanadium redox battery energy storage power station is very slow, and it is very likely that the key growth and development period will be missed; the lithium batteries for electric vehicles is expected to enter the outbreak period after 2020, the market positioning of cascading lithium batteries has been blurred. The scale of power stations, application scenarios, and operational safety all need to be studied urgently, and there is still a lot of work to be solved.

In the future, battery energy storage products will develop in the direction of large-capacity, large-scale, customized, safe, easy to recycle, adaptable, and digitalized.
