Shulou(Shulou.com)11/24 Report--

CTOnews.com, December 15, 2008, at the third Battery Day of Honeycomb Energy, Honeycomb Energy released a new generation of systematic solution for high safety power battery-Dragon scale Armor Battery, which uses thermoelectric separation and space function integrated design to improve individual safety and system safety; at the same time, it also has the advantage of long range, and its lithium iron phosphate version can enable electric vehicles to have a range of more than 800km.

In addition, Honeycomb Energy announced the name of ultra-high-speed lamination technology 3.0, "Feidui", released high-manganese iron-nickel battery and nano-mesh silicon negative electrode, and announced the company's layout in the field of energy storage, opening the "power battery + energy storage battery" two-wheel drive strategy.

The technical efficiency of the first generation lamination of honeycomb energy is 0.6 seconds per chip, and the second generation is 0.45 seconds per chip. The third generation of "flying stack" technical efficiency has been trying to catch up with and surpass the winding process, reaching an efficiency of 0.125 seconds per piece. Compared with the previous generation of Honeycomb Energy stacking machine, the third generation of "Flying stacking" technology occupies an area reduction of 45%, and the efficiency increases by more than 200%. The third generation of "flying stack" technology also integrates pole unwinding, cutting, hot pressing functions, laminated CCD on-line monitoring, HI-POT on-line monitoring, to achieve full inspection of single-chip defects. In terms of consistency, an innovative pressing tool structure is adopted to improve the accuracy of laminated alignment.

In terms of products, Honeycomb Energy has also released technologies related to high manganese iron and nickel and nano-mesh silicon negative electrodes.

High mn-Fe-Ni battery is a new product scheme put forward by Honeycomb Energy for the energy density of lithium iron phosphate battery exists in the ceiling. Because it does not contain cobalt, the cost of high manganese iron nickel battery is controllable, and its energy density is higher than that of lithium iron phosphate. Compared with the lithium iron phosphate battery pack, the honeycomb energy high manganese iron nickel battery pack can improve the range by 100 kilometers, improve the low temperature performance by two times, and reduce the cost of the whole package by 9.5% compared with the ternary battery pack with the same volume density. Honeycomb Energy estimates that the weight energy density of high mn-Fe-Ni battery package is 220WH / kg, the volume energy density is 503Wh / L, and the mass production time is estimated to be 2024.

Nano-mesh silicon negative electrode is a negative electrode technology scheme put forward by Honeycomb Energy for high energy density battery. For this purpose, Honeycomb Energy independently developed and built network bundle silicon technology, silicon-carbon fusion technology, double-layer coating technology, and the cycle life increased by 10% compared with similar imported products. This anode material is characterized by high capacity, high first effect, low expansion, low gas production, long life and support for 4C fast charging. Honeycomb Energy predicts that nano-mesh silicon negative electrode with high nickel cathode will be the first to be used in large cylindrical cells to achieve energy density ≥ 300Wh/kg. In 2025, the high energy density cell production capacity of honeycomb energy with nano-mesh silicon negative electrode will reach 5GWh.

Honeycomb Energy also announced the business planning of energy storage at the brand conference for the first time, and named the initially formed ecological chain as Honeycomb Ecology.

CTOnews.com learned that honeycomb energy application board IPO prospectus shows that from 2019 to 2021, honeycomb energy R & D expenses accounted for 20.71% of business income, with a cumulative R & D investment of nearly 1.5 billion yuan.
