Eco Factor: High-capacity cost-effective lithium-ion battery for electric cars and renewable energy storage.
Panasonic has announced the development of a high-capacity lithium-ion battery module that is being claimed to be much safer and more cost-effective than other modules being used in electric cars and for storing solar energy. The 1.5KWh battery module is constructed from 140 individual lithium-ion battery cells that are connected together.
The module has a voltage of 25.2V and a capacity of 58Ah. The 18650-type lithium-ion cells are placed in seven serially-connected rows of 20 parallel-connected battery cells. The arrangement, according to Panasonic, prevents a serious loss of performance even if some individual cells fail. Additionally, the company’s cell safety technology also prevents overheating and short circuits by placing a layer of heat-resistant metal oxide insulation in between the positive and the negative electrodes.
