Lithium-ion batteries (LIB) are widely used in consumer electronic devices. They have high energy densities and are rechargeable, resulting in sustained performance across many charging cycles. LIBs consist of an anode, electrolyte, separator, and a cathode, see Figure 1 below. LIBs use a separator, which is a permeable membrane placed between the battery’s anode and cathode. The separator prevents the electrodes from contacting each other. This prevents electrical short-circuits while allowing transport of the ionic charge carriers, completing the circuit and allowing current to flow in the electrochemical cell.
The market for LIBs is expected to grow at a rate of 30% from now until 2030. Apart from consumer electronics, like laptops and cell phones, electric vehicle manufacturers are becoming one of the most significant drivers for growth in LIBs.
The battery separator is a critical component of the LIB. It typically consists of a polymeric membrane forming a porous layer. Apart from chemical and electrochemical stability, the separator should be mechanically strong to withstand the high-tension during battery construction.
The separator has a strong impact on cell performance, battery life, safety, and reliability. Further LIBs for high power applications are increasingly gaining widespread interest; hence it is imperative that industry develops new separators to meet performance, safety, and cost targets.
