YOKU ENERGY TECHNOLOGY LIMITED

YOKU is dedicated to providing customers with the best portable power solution available therefore great emphasis is placed in strong R&D capabilities. YOKU's R&D teams are drawn from the most highly talented people in the lithium-ion polymer battery industry. To date we have developed more than 1000 types of battery products for small, medium and large scale projects, batteries with capacities ranging from 100mAh to 10,000mAh, standard battery products, high temperature series products, and high discharge rate products.We continue to develop new products to meet the varied customer requirements and changing application needs yet simultaneously the performance of safety, energy density, temperature characteristics, discharge platform, impedance and cycle life are part of a continuous improvement process. YOKU owns the intellectual property for and invented the manufacturing process of the lithium-ion polymer battery products. Our technology of lithium-ion polymer battery design is that of a stacking type. Multi-layers of electrode slices are connected in parallel after being pressed within the cell. This technology requires less equipment space and there are no acute electrode turning angles in the cell making it easy to manufacture. Consequently with this technology the final pass rate surpasses 95%. Patent applications have been made and are pending for this technology.Through YOKU's continuous investment in R&D the Company has been able to provide better lithium-ion polymer battery products in comparison to others in the industry when considering large capacity of a single cell, high discharge rate and high safety. Continuing developments are producing opportunities in new application areas, for example, YOKU has recently developed a new series of battery products that can be operated at temperatures in excess of 80°C making them suitable for military telecommunication applications. In summary the benefits of the depth and professional experience of YOKU's technical teams when partnering with customers is apparent when our customers see how rapidly they can realise their desired product solution - new product designs taking typically only 20 days from concept to sample! Our products are UL and CE approved,also have passed the SGS testing. They are widely used for various digital products and powerdriven products,such as portableDVDs, portable computers, mobile phones, bluetooth devices, MP3/MP4 players, PDAs, R/C plane, powerdriven tools and toys, batteryoperated bicycles or cars, etc. We own the international top class R&D team, advanced production equipments and many patents, our technology development is always on the leading position in the industry. We are able to provide rapid, overall and customized design and service based on either normal requirement from clients or various special physical structure and performance request. We have achieved a series of breakthrough firstly in lithium-ion polymer battery research and application in China. The performance indexes of our products are the first class level in the world, especially for the manufacturing processes and safety performance of single large capacity battery cell, we are even better than our competitors. We have a high start and big investment. We have introduced ISO quality management system since our company was founded. The management system of R&D, manufacturing and service has been established according to the GB/19001-ISO9001 standard within the company. This has strongly ensured every process of our production meet international standard, strongly ensured stable performance, dependable quality, reasonable cost of our products. We have been certificated under ISO9001 and ISO14001. Our sales network has covered the mainland of China, our products are also exported to north America, Europe, south and east of Asia and Taiwan.YOKU is developing a new generation technology of lithiumion polymer battery, With this technology, the battery will be absolutely environmentfriendly products (no heavy metal) and have the characters of simple manufacturing process, lower cost, high safety, high energy density, long cycle life, can discharge by large current excellently and be used in wide range of temperature, using the new layered cathode material which is developed and made by ourselves. We have also invested to produce the supercapacitors (physics battery), and the electric motor cars powered by the supercapacitors have entered the market. We are now trying to make electric motor car powered by both supercapacitors and lithiumion polymer battery.
