As lithium-ion laptop batteries have become more and more popular in the market, vgp-ac19v10 has updated itself rapidly in standby time, conductivity, electrolyte and even protection circuit. How come does it achieve such improvements so effectively in a short period? Let’s have a look at its manufacturing process.


Normally, in the factory, lithium-ion Sony Vaio laptop battery has designed with several complex primary working procedures which are strictly operated and examined seriously by technicians. To prevent from any accidents later, any details of these four steps are critical to us.

Slurrying: Before assembling, battery cells for vgp-ac19v10 are completed by a more complicated process which is the most important trade secret to Sony. Therefore, now it turns to combine the active substance of fine powder with specialized solvent in anode and cathode. After stirred by high rate, the powders have been crank out into useful electrode materials.

Coatings: These made-up slurries should cover the surface of metal foil equably and then dried. Therefore, the pole piece of positive and negative electrodes has completed successfully. As we have talked about the updated materials polysilicon, the actual secrets of Sony Vaio laptop battery are not only this simple step, which have higher requirements on technologies.

Assembling: Up till now, it has just started to combine and install the electrode pieces with each other revolving around poleshank of Sony laptop battery cells. After pouring into electrolyte, vgp-ac19v10 has been completed basically with sealing and some other steps.

Testing: The step has been ignored by many nonregular manufacturers to save more money. Such a process can only be operated on the original Sony Vaio laptop computer. With specialized battery testing devices, vgp-ac19v11 can be separated from vgp-ac19v10 in compatibility and security. Then we are waiting for leaving and going to the market.
