How MAHA reduced the self-discharge of NiMH Batteries.

Modern Ni-MH batteries consist of two metal stripes ( anode and cathode ), which are separated by a non-conductive porous plastic foil ( separator ). These three stripes are laid on top of each other and are winded to a coil. This coil is put in a metal can and immersed with a liquid ( electrolyte ). Then the metal can is closed with a cap. The self discharge of Ni-MH batteries is caused by three main reasons:

* the chemical decomposition of the cathode,
* the natural disaggregation of the anode,
* Impurities of the anode.

SANYO ENELOOP AA 2000 mAh Rechargeable Batteries

Purchase Sanyo eneloop batteries @ [thomasdistributing.com]

SANYO’s next-generation nickel metal hydride battery ‘eneloop’.

Batteries have a property to release the stored energy in small amounts (this phenomenon is called ‘self-discharge’). This property is particularly noticeable in rechargeable batteries such as Nickel Metal Hydride Batteries etc. as compared to dry cell batteries, hence disabling rechargeable batteries from becoming batteries that ‘customers can use immediately after purchase’. For this reason, rechargeable batteries couldn’t be used unless charged after purchase and so lagged behind dry cells in convenience. This new product’s main property is that it has introduced great improvements in self-discharge properties (residual ratio after one year of non use is 85%*4, in temperature conditions of 20 degree Celsius according to SANYO research). Through this breakthrough development, SANYO has realized a rechargeable battery that can challenge dry cell batteries in user-friendliness through features such as making possible use immediately after purchase or once charged, its ability to be used anytime.
