Lithium Polymer (commonly called Li-Poly) are one of the latest developments in rechargeable battery technology, these new cells are a great advancement in technology from the older Nickel cadmium cells (referred to as NiCd) and nickel metal hydride cells (NiMH).

Among the advantages of Li-poly cells one of it unique features is that there is no metal disks in the cells unlike others this enable the cell to be virtually any shape desired. This means that for the mobile phone and laptop market these cell are ideal. Due to this usage of the cell in such markets as the telecommunication, it has meant the mass production of cells and hence the price of the cells is constantly dropping.

Lithium Polymer Suppliers and manufactures:

Kokam

Kokam possesses its own unique, proprietary technology (the Superior Lithium Polymer Battery or SLPB), which has proven marketability over existing and perceived competition. Substantial opportunities exist to tap into the market of cellular phone manufacturers and distributors who seek better lithium-ion batteries than those readily available on the market. The challenge is to bring cost-efficiency to the major channel members and OEMs, and Kokam has met this challenge. As more and more of the world's population have gained an interest in these products (as well as notebook computers and similar portable devices), the demand for lithium-ion batteries has also increased and will continue to increase over the next five years. Kokam's particular patented design employing the next generation lithium-ion/polymer technology, will increasingly occupy more and more of the total rechargeable battery sales in this industry. Based on its advanced technology and price competitiveness, Kokam's market share will be extended as fast as it is able to increase production capacity. The cellular phone industry represents very strong demand for this next generation technology, which far exceeds the overall industry's production capacity. Additionally, the size of market for notebook pc and PDA is being increased fast will be a great opportunity for Kokam. Kokam makes high standard and reliable re-chargeable Lithium battery and its processing equipments and also develop new advanced technologies for future.
