Note (1): Bipolar lead-acid batteries are being developed which have energy densities in the range from 55 to 60 Wh/kg (120–130 Wh/l) and power densities of up to 1100 W/kg (2000 W/l).
The term “bipolar battery” refers to the presence of bipolar electrodes inside a battery module. Theoretically, this technology may be applied to batteries with different chemistries. In reality, among all the various bipolar batteries, only lead-acid battery modules have reached the commercial production stage.
Today’s best lead acid batteries achieve about 38Wh/kg. To say it another way they are only 23% efficient (rounding up). This new bipolar technology can create batteries ranging from 50Wh/kg to 63wh/kg. That is a 30% to 65% increase when contrasted with comparable batteries on the market! Here are some of the potential benefits:
• However, bipolar electrode technology has a chance to seriously improve battery performance if successfully implemented with high-capacity battery chemistry, such as lithium-ion. • acceptable price and easy handling of substrate materials. It’s expected that setting up mass production and the commercialization process will take at least a decade.
The comparison demonstrates that with batteries of the same weight, bipolar lead-acid batteries are capable of providing more instant power (W), while lithium-ion single electrode modules store more electrical energy (Wh). Speaking of material handling equipment, the heavier the equipment, the more instant power is required.
Each battery is grid connected through a dedicated 630 kW inverter. The lead–acid batteries are both tubular types, one flooded with lead-plated expanded copper mesh negative grids and the other a VRLA battery with gelled electrolyte.
