IEEE 1725-2011 pdf free.IEEE Standard for Rechargeable Batteries for Cellular Telephones.
IEEE 1725 establishes criteria for design analysis for qualification, quality, and reliability of rechargeable lithium-ion (li-Ion) and lithium-ion polymer (li-Ion polymer) batteries for cellular telephone applications. Also included in the standard are: battery pack electrical and mechanical construction. packaging technologies, and pack and cell level charge and discharge controls and overall system considerations.
1.2 Purpose
The purpose of this standard is to ensure reliable user experience and operation of cell phone batteries. The battery and cellular telephone industries need standardized criteria for design and qualification of rechargeable battery systems and for verifying the quality and reliability of those batteries.
1.3 Introduction
This standard guides manufacturers/suppliers in planning and implementing the controls for the design and manufacture of Li-Ion and Li-Ion polymer rechargeable battery packs used for mobile phones.
The provisions of this standard work together to detine approaches to design, test, and evaluate a cell, battery pack, adapter, and host device to mitigate battery system failure. Additionally, this standard provides recommendations for user education and communication materials. This approach suggests the interfaces between subsystems (e.g., cell, battery pack, host device, and power adapter) and end users are as important to system reliability as is robust subsystem design and testing. This standard, therefore, includes subsystem interface design responsibilities for each subsystem manuficturer/supplier, and it provides messaging and communication provisions for end-user awareness. Therefore, the responsibility for total system reliability is shared between the designers/manufacturers/suppliers of the subsystems and the end user. Compliance to this standard requires adherence to all provisions of the standard.

3. Definitions
For the purposes of this document. the following terms and definitions apply. The IEEE Standards Dictionary: (Jlossarv of Terms & Definitions should be consulted for terms not defined in this clause.5
abuse: use of product in a way that is not intended by the manufacturer/supplier but that may result from unreasonable or malicious human behavior or unreasonably extreme conditions or environments.
actie authentication: A method of validation of a battery andor accessory where the system makes the compatibility decision independent from the user: for example, the use of a secure memory device within the battery pack that communicates to the host that the pack is suitable for use with a specific original equipment manufacturer’s (OEM’s) mobile phone.
actke charger: A charger that has a communication channel and interacts with the host device
adapter: A device that transforms the available power from an external source (e.g.. ac wall outlet, airline. or automobile outlets) to the power used by the host.
authentication: Any method of validation of a battery andor accessory designed to ensure compatibility with a specific host device.
bter,/batterv pack: An assembly of any number of Li-Ion or Li-Ion polymer cells, associated electronics, battery packaging, and connector(s).
burr: A sharp metallic projection at the edge of an electrode foil that may penetrate the separator and cause an internal short in a Li-Ion or Li-Ion polymer cell.
cause-and-effect (Fishbone) diagrani: A branching, skeletal diagram used to illustrate cause and effect. Main branches are typically labeled “manpower, methods, materials, and machinery.” This diagram is also known as an Ishikawa diagram.
cell: Rasic manufactured Li-Ion or Li-Ion polymer unit providing a source of electrical energy by direct conversion of chemical energy that consists of electrodes, separators. electrolyte, container, and terminals, and that is designed to be charged electrically.
cell core: Internal cell assembly consisting of positive and negative electrodes integrated with the separator. Electrodes and separator may be spirally wound (‘jelly roll”) or stacked (“cut and stack”) in a planar arrangement
cell leakage: The appearance of the cell electrolyte outside the contained components. L.eakage is evidenced by liquid or condensed electrolyte composition external to the cell on the cell surface.
charge control: A means of ensuring that a cell is charged in accordance with its manufacturer’s specifications.IEEE 1725 pdf download.
