There may be non-thermal cosmic rays during big-bang nucleosynthesis (BBN)
epoch (dubbed as BBNCRs). In this paper we investigated whether such BBNCRs can
be the origin of Lithium problem or not. It can be expected that BBNCRs flux
will be small in order to keep the success of standard BBN (SBBN). Our
numerical results showed that the extra contributions from BBNCRs can account
for the $^7$Li abundance successfully, while lift $^6$Li abundance an order of
magnitude.
