(a) the origin of the development journey: in 2012, its predecessor, the great wall autodynamic battery enterprise, was established to begin the study of power batteries. In 2016, the hive energy technology centre was inaugurated. In february 2018, hive energy technology ltd. Was formally established, completely stripped from the great wall's car and independently oriented to industry-wide development. Rapid expansion: in 2019, the tin-free r & d centre was established and in july of the same year, a global cell of cobalt-free materials was launched. In 2020, the national contractor was awarded a strategic share of 1 billion yuan; in november of the same year, saarland, germany, was selected to build a battery plant. In 2021, production bases were constructed in multiple locations, cobalt-free batteries were cut off and gabs were first installed on the top10 list. In 2022, the shanghai research and development centre was established to submit an ipo application. In 2023, the dragon armored battery was displayed at the shanghai car show, and in october of the same year was ordered by nearly 90 gwh batteries in the european region of the bmw group. Operation-wide power cell operations: material innovation, introduction of the world's first cobalt-free material batteries, development of high nickel triple batteries, etc.; process innovation, pioneering the application of the stacking process in the field of square hard-hull batteries, introduction of the third generation ultra-high-speed stack technology, "flying " ; power core innovation, introduction of short-stabbing batteries, covering multiple scenarios, complete chemical systems; structural innovation, introduction of lctp3. 0-lon caps. Storage operations: the provision of research and development, production, marketing, transportation and energy operations services for all-system energy-capable products and systems, and the issuance of all-system energy-capable cores and products, such as the l500 325ah power-storage dedicated cores, ultra-basic household-capacitation systems, etc., for three major scenarios: electricity, business and family. Technical strength research and development team: there are over 1,500 r & d teams, more than a third of them have master's degree, doctoral degree, and more than 60 top-level experts from europe and the united states, japan and india. R & d centres: the globalization of r & d centres, the establishment of china's paul, shanghai and tinless r & d centres, korea, india and the united states of america, europe and japan. The company has applied for over 2000 patents on various technologies, of which over 800 are patented for inventions and 48 are applications for international patents for pcts. The corporate cultural mission: making green energy accessible. Vision: be a leading global energy internet technology company. Entrepreneurship: moving forward with innovation. Core values: client-centred, hard-core, innovative and synergistic. In 2021, the award was awarded to the global new energy car front and innovation technology. In august 2022, he was selected as "2022 china's innovative enterprise 50 strong". In 2023, he was elected to the "global unicorn list 2023", ranked 71st; he was named as "ten good energy power battery providers in the china energy industry 2023" and was top of the 2023 power battery industry development index, published by the ministry of industry during the world congress on power batteries 2023。
