The Panasonic brand maker said it has boosted its production capacity of batteries insulated with heatproof layers to five million units per month, up from 100,000 in April.

Japanese rivals and battery market leaders Sony Corp. and Sanyo Electric Co. Ltd. have been hit by recalls of high-power batteries for PCs and cellphones, following much-publicized incidents in which batteries ignited.

Matsushita hopes to raise production of heat-resistant batteries for laptops first, and aims to raise production of insulated batteries to half of all lithium-ion batteries it makes in 2009, said spokesman Akira Kadota.
