(Yicai) Nov. 13 -- Shares of Senior Technology Material jumped after the leading Chinese producer of lithium-ion battery separators announced a collaboration with Japan's Daiso Chemical to develop materials for semi-solid batteries, an emerging type of technology for electric cars and laptops.

Senior [SHE: 300568] surged as much as 9.3 percent intraday and closed 8.7 percent elevated at CNY13.03 (USD1.80) in Shenzhen today.

The Chinese company signed a cooperation agreement with Daiso Chemical and its subsidiary in Shanghai to industrialize semi-solid battery separator products, the Shenzhen-based company announced yesterday.

Semi-solid batteries offer greater energy density and enhanced safety compared to traditional liquid-state batteries, while being more cost-effective to produce than solid-state alternatives.

Under the agreement, Daiso Chemical will appoint Senior as its exclusive partner for the semi-solid battery separator project. Senior will process polymer raw materials provided by Daiso Chemical into separators and sell them to battery manufacturers.

The partnership is poised to accelerate the commercialization of semi-solid battery technology, which is based on intellectual property developed and patented by Daiso Chemical's parent company, Osaka Soda, a renowned Japanese chemical giant specializing in high-value-added functional chemicals.
