The challenge to incorporate Si into Li-ion battery anodes has attracted much attention. Binding agents are a critical component in a battery that may also be used to enhance electrode performance. Herein, we report the use of galactomannans—a low-cost, environmentally friendly, biorenewable polymer—as a novel binding agent for Si-containing electrodes. Silicon-containing electrodes with as low as 5 wt% binder show large reversible capacities with >90% charge retention after 100 cycles without…
