Advanced Hybrid Batteries(AHB)R
Introduction to Advanced Hybrid Battery Technology
Because of its high electrode energy density, the traditional Li-ion batteries have the strong advantage in battery performance (including the energy density and high rates). The simple manufacturing process, excellent integrity in product quality and reliability, and low manufacturing cost make the Li-ion batteries more competitive toward the traditional Li-ion Polymer batteries. However, due to its limitation of the metal outer cases, the new product development of Li-ion batteries is less flexible and the manufacturing process is rigid and most suitable for mass volume production. This also limits its scope of the applications. Traditional Li-ion Polymer batteries (the first generation Li-ion Polymer batteries, or the Bellcore Li-ion Plastic batteries) emphasize on the excellent adhesion between the electrode and the home made separator. The excellent flexibility of its exterior design makes Li-ion Polymer batteries more suitable for the market with fast changes in product models. Nevertheless, the disadvantages for keeping the excellent adhesion are:
  • The large percentage in electrodes and separator makes the decrease in the electrode energy density as well as the drastic reduction in the puncture strength of the separator. This will greatly diminish the product performance, reliability and manufacturability.
  • The electrode and separator have to be hot pressed to form the bicell. This will increase the production complexity and cost.
  • To avoid the crushing of the voids during hot pressing and to generate the voids in electrodes and separators, the plasticizer has to be added before hot pressing and to be extracted to generate the spaces for later injected electrolytes. This redundant processes cause the inferior cost and performance compared to the traditional Li-ion batteries.
SYNergy ScienTech Corp. had developed both traditional Li-ion battery and Li-ion Polymer battery before. The advantage and disadvantage of those two traditional battery technologies are well known. Supported by the government funds, SYNergy had completed the development of the Advanced Hybrid Battery (Trade Mark: AHB) and installed the mass production line at the end of 2002. In the middle of 2003, the mass production of Advanced Hybrid Batteries was formally kicked off. The full production capacity can be 300K~600K/month. The AHB technology combines the merits of the electrode technology of the traditional Li-ion batteries as well as the assembly technology of the traditional Li-ion Polymer batteries, and avoids the weakness of those two batteries in production and performance. Besides, the proprietary know-how sin the electrolytes, interface adhesion technology, the formation and process technologies make the Advanced Hybrid Battery outstanding and unique in the world.
The Advantages of Advanced Hybrid Batteries
  • No Electrolyte Leakage Problem
    Traditional battery electrolytes are liquid solutions such as aqueous solutions or organic solvents. Any tiny crevices would cause electrolyte leakage problem. If the electrolyte is a strong acid or strong base, it would further cause product failure. The proprietary electrolyte in Advanced Hybrid Batteries is thoroughly absorbed and the advanced sealing technology developed by SYNergy avoids the electrolyte leakage problem.
  • Development Toward Thinner Batteries
    The thickness of the AHBP4 battery can be as thin as 0.6mm. Because it contains no free liquid electrolyte, there is no need for metal outer cans. It only takes 0.1mm thick Al laminate film to pack the battery. As to the increase in capacities of the batteries, it can be accomplished by stacking multiple layers of electrodes or enlarging the electrode areas.
  • Better Battery Design Flexibility
    The size of developed AHB can be as small as stamps, name cards, or as large as paper size A4 or A5. They can be of curve, triangle or donut shapes, regardless of the costs. Product designers do not have much flexibility in adopting traditional Li-ion batteries because of the limitations on the choice of battery dimensions. However, the presence of AHB unique feature in size flexibility provides the designers more space for creativity.
  • Light-weight and Low Cost
    AHB not only possesses the flexibility in size changes, but also saves the heavy metal container and complicated cap, naturally lowering a lot of weights. This promotes the specific energy density and reduces the battery materials cost a great deal. Also the excellent manufacturability of the AHB can expectedly lower the manufacturing cost as well.

The Applications of Advanced Hybrid Batteries
  • Advanced Hybrid Batteries possess a rather wide scope of applications. Especially, the trend on nowaday IT products is moving toward the direction of having light-weight, short, and small products. The feature of the AHB is coincident with this trend.
  • Associated application products include MD players, handy recorders, PDAs (personal digital assistants), NBPCs (notebook personal computers), cellular phones, DSCs (digital still cameras), WEs (wireless earphones), and MGPs (mobile game players).
  • Because the thickness of the Advanced Hybrid Batteries can be very thin that the conventional Li-ion batteries can not accomplish, a lot of applications are developed totake advantaces of the Advanced Hybrid Batteries. Those applications include pen computers, pen digital cameras, new style walkman, credit cards, smart cards, other electronic applications and commercial products.
