6月22日从中国绿发投资集团获悉，该集团旗下北京绿发中科锂电容科技有限公司（以下简称中国绿发锂电容公司）自主研发设计制造的5兆瓦级全碳型超级电容功率舱日前完成全套型式试验，顺利取得具备国际互认效力的中国合格评定国家认可委员会（CNAS）认证报告。这是国内首款、全球首台整舱通过CNAS认证型式试验的5兆瓦级全碳型超级电容功率储能设备。

On June 22nd, it was learned from China Green Investment Group that the 5-megawatt-level all-carbon supercapacitor power module independently developed and manufactured by Beijing Green Development Zhongke Supercapacitor Technology Co., Ltd. (hereinafter referred to as China Green Development Supercapacitor Company) has recently completed all types of tests and successfully obtained the certification report of the China National Accreditation Service for Conformity Assessment (CNAS), which has international mutual recognition effect. This is the first in China and the first in the world for an entire module to pass the CNAS certification type test of 5-megawatt-level all-carbon supercapacitor power energy storage equipment.

当前新型电力系统建设加速推进，储能设备在电网调频领域扮演着日益重要的角色。传统锂电储能设备储存的总电量较高，但循环寿命仅数千次，无法适配高频充放电。相比之下，超级电容储存的总电量虽不及锂电储能设备，但其功率密度极高，可对电网的调频指令进行毫秒级响应，且循环寿命超长，适配频繁、高强度的调频场景。因此，超级电容适合与传统锂电储能设备组合使用。

At present, the construction of the new power system is accelerating, and energy storage equipment is playing an increasingly important role in the frequency regulation of the power grid. Traditional lithium-ion energy storage devices have a relatively high total storage capacity, but their cycle life is only several thousand times, which is not suitable for high-frequency charging and discharging. In contrast, supercapacitors have a total storage capacity lower than that of lithium-ion energy storage devices, but their power density is extremely high. They can respond to the frequency regulation instructions of the power grid within milliseconds and have an extremely long cycle life, which is suitable for frequent and high-intensity frequency regulation scenarios. Therefore, supercapacitors are suitable for being combined with traditional lithium-ion energy storage devices.

“相较市场上常见的混合型超级电容和双电层电容，全碳型锂离子超级电容具备循环寿命更长、安全性更高、低温衰减更小、无锂枝晶燃烧风险等优势。”中国绿发锂电容公司董事长厉明表示。

"Compared with the common hybrid supercapacitors and double-layer capacitors on the market, the all-carbon lithium-ion supercapacitor has advantages such as longer cycle life, higher safety, smaller temperature-dependent degradation, and no risk of lithium dendrite combustion." said Li Ming, the chairman of China Green Energy Lithium Capacitor Company.

厉明介绍，这款超级电容功率舱内置中国绿发锂电容公司自产4500法拉大容量全碳型锂离子超级电容单体。超级电容单体采用预嵌锂技术，多孔电极结构设计，能量密度达到16瓦时每千克（Wh/kg），功率密度达到18千瓦每千克（KW/kg）。功率舱采用主动均衡策略，可实时调度22400支超级电容单体，簇级动态压差仅64毫伏，转换效率超95%，瞬时功率响应速度在10毫秒内，整舱循环使用寿命超百万次级别，适配每日数百次高频充放电工况。

Li Ming introduced that this super capacitor power module is equipped with 4500 Farad large-capacity all-carbon lithium-ion supercapacitor cells produced by China Green Energy Lithium Battery Company. The supercapacitor cells adopt pre-lithium embedding technology and porous electrode structure design, with an energy density of 16 watt-hours per kilogram (Wh/kg) and a power density of 18 kilowatts per kilogram (KW/kg). The power module adopts an active balancing strategy, capable of real-time scheduling of 22,400 supercapacitor cells, with a cluster-level dynamic pressure difference of only 64 millivolts, a conversion efficiency of over 95%, a instantaneous power response speed within 10 milliseconds, and an overall module cycle life of over a million times, suitable for daily hundreds of high-frequency charging and discharging conditions.

“不仅如此，该设备在海拔5000米极限工况下，可持续稳定输出5兆瓦功率，是国内少数可覆盖青藏高原全域风光储能项目的兆瓦级超级电容装备。”厉明说。

"Moreover, this equipment can continuously and stably output 5 megawatts of power even at the extreme altitude of 5,000 meters. It is one of the few megawatt-level super capacitor equipment in China that can cover the entire area of the Qinghai-Xizang Plateau for photovoltaic energy storage projects." Li Ming said.

本次通过型式试验的5兆瓦全碳型锂离子超级电容功率舱，将在青海东岳独立储能项目中落地应用。其将为储能电站带来毫秒级快速响应，实现百万次超长循环，全生命周期无需更换电芯，同时适配高原极寒环境，无需额外配套温控、增压设备，可大幅降低场站配套投资，提升电站调频收益。

The 5-megawatt all-carbon lithium-ion supercapacitor power module that passed the type test will be put into practical application in the Dongyue Independent Energy Storage Project in Qinghai. It will bring millisecond-level rapid response to the energy storage station, achieve ultra-long cycles of over a million times, and require no replacement of battery cells throughout its entire life cycle. At the same time, it is suitable for the extremely cold and high-altitude environment of the plateau, and does not require additional temperature control or pressurization equipment. This will significantly reduce the investment for on-site facilities and enhance the frequency regulation income of the power station.
