（1） Foreign situation

Panasonic electric vehicle energy Co., Ltd. and Toyota Motor Co., Ltd. have successfully developed a new type of square nickel zinc battery for oil electric hybrid vehicles, and have begun to provide industrial samples;

The secondary battery manufacturers in South Korea are mainly Samsung and LG. In 2000, Samsung SDI and LG Chemical, the heavyweight enterprises in the group, respectively, invested in the research and development of nickel zinc batteries and specialized in the production of nickel zinc batteries;

ERC of the United States has invested a lot of energy in the research and development of nickel zinc batteries for electric bicycles and motorcycles and has achieved certain results;

Powergenix mainly researches and develops nickel zinc cylindrical batteries for electric tools and electric vehicles. At present, the products have entered the practical test stage.

According to the research status of nickel zinc battery abroad, the research direction of the foreign market is mainly focused on the nickel zinc battery for electric tools and power supply, and great achievements have been achieved.

（2） Domestic situation

At present, Henan Xinxiang Huanyu Battery Co., Ltd. focuses on the research and development of nickel zinc batteries in the low capacity cylindrical market to replace its original nickel cadmium battery market. At present, Henan Xinxiang Huanyu Battery Co., Ltd. has made great progress in the research and development of nickel zinc batteries, but it does not have the conditions for industrialization.

BYD is also conducting research and development of nickel zinc batteries, which are mainly developed for BYD's automobile power supply. At present, it has a corresponding small-scale production line, and the batteries produced are mainly used for testing with automobiles, without large-scale mass production.

Shenzhen Waterma Battery Co., Ltd. researched and developed a cylindrical rechargeable nickel zinc battery for lawn lamps, but later withdrew from the market due to immature product development.

Hunan Liyuan new material, Jiangsu Chunlan power supply Co., Ltd. and Hunan Shenzhou Technology Co., Ltd. also focus on the research of high-power nickel zinc battery.

However, the nickel zinc battery technology in China is relatively backward, and the products can not meet the quality requirements.

Shenzhen BPI is one of the few nickel zinc battery manufacturers in China, with stable performance. It has passed the testing of many domestic and foreign testing institutions. Welcome to consult!
