A high-power and large-capacity lithium battery for electric bus is provided. The battery stack comprises a thermal protection device with dual terminals and is made from certain materials in a manner such that it avoids a mutual contact between upper and lower pole pieces to cause a short circuit, resulting from bounce of pole pieces caused by bus vibration or external mechanical shock etc.; the stress of external terminal is evenly dispersed, thus the battery is safe, steady, electrolyte resistant, anti-aging and advantageous to heat dissipation with reduced failure rate and high efficiency during movement of bus, so as to solve the connection problem resulted from series-parallel connection of single cells to constitute the battery. The batteries have small size, large capacity and high power, each having a safety protection unit, simple to make and convenient.
