freevirtualstrippoker| Heavy documents were released, the concept of lithium batteries broke out, and Tianli Lithium Energy, Jinyang shares, etc. rose daily limit

Special topic: the A-share concussion arrangement is expected to maintain the concussion and upward pattern.

Securities Times online newsFreevirtualstrippokerThe concept of lithium battery rose strongly in intraday trading on the 9th. As of press time, Tianli LiNeng, Jinyang shares, Blue Ocean Huateng, LinkedIn Technology (rights protection) "20cm" rose by the daily limit, Xiang Fenghua, Nebula shares, Dangsheng Technology, Zijian Electronics and so on rose by more than 10%. Fengyuan shares and Baichuan shares also rose by the limit.

On the news side, on May 8, the Ministry of Industry and Information Technology issued the Lithium Battery Industry Standard conditions (2024) (draft for soliciting opinions), which proposed to guide enterprises to reduce manufacturing projects that simply expand production capacity, strengthen technological innovation, improve product quality, and reduce production costs.

The draft for soliciting opinions requires that lithium battery enterprises should have independent production, sales and service capabilities of related products in the lithium battery industry.FreevirtualstrippokerThe annual expenditure on R & D and process improvement is not less than 3% of the main business income, encourage enterprises to obtain the qualifications of independent research and development institutions, engineering laboratories, technology centers or high-tech enterprises at or above the provincial level, encourage enterprises to establish green factories, encourage enterprises to build or participate in the joint construction of pilot platforms, major products have patents for technological inventions, and the actual output in the previous year is not less than 50% of the actual production capacity in the same year.

The draft also requires that the energy density of single battery using ternary material (lithium nickel cobalt manganate) is ≥ 230Wh/kg, the energy density of battery pack ≥ 165Whhand kg, the energy density of single battery using other materials such as lithium iron phosphate ≥ 165Wh/kg, the energy density of battery pack ≥ 120Wh/kg. The power density of single cell is ≥ 1500W/kg, and the power density of battery pack is ≥ 1200W/kg. The single battery cycle life ≥ 1500 times and the capacity retention rate ≥ 80%, the battery pack cycle life ≥ 1000 times and the capacity retention rate ≥ 80%.

The draft for soliciting opinions requires that the safety of lithium battery products should meet the requirements of relevant mandatory standards and be tested and qualified by testing institutions with corresponding qualifications. Mandatory standards include, but are not limited to: safety Technical Specification for Lithium Ion batteries for Electric bicycles (GB43854), Safety requirements for Lithium batteries and Battery packs for Electric Energy Storage Systems, etc.

Compared with the previous version, there is a significant increase in the number of mandatory standards mentioned in the draft. The draft also encourages enterprises to formulate and implement product technical standards or specifications that are higher than national or industry standards.
